+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but

+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally

+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+# zkSync Era: A ZK Rollup For Scaling Ethereum
+
+[![Logo](eraLogo.svg)](https://zksync.io/)
+
+zkSync Era is a layer 2 rollup that uses zero-knowledge proofs to scale Ethereum without compromising on security or
+decentralization. Since it's EVM compatible (Solidity/Vyper), 99% of Ethereum projects can redeploy without refactoring
+or re-auditing a single line of code. zkSync Era also uses an LLVM-based compiler that will eventually let developers
+write smart contracts in C++, Rust and other popular languages.

+//! Seal criteria is a module system for checking whether a currently open block must be sealed.
+//!
+//! Criteria for sealing may vary, for example:
+//!
+//! - No transactions slots left.
+//! - We've reached timeout for sealing block.
+//! - We've reached timeout for sealing *aggregated* block.
+//! - We won't fit into the acceptable gas limit with any more transactions.
+//!
+//! Maintaining all the criteria in one place has proven itself to be very error-prone,

+/// `WitnessGenerator` component is responsible for generating prover jobs
+/// and saving artifacts needed for the next round of proof aggregation.
+///
+/// That is, every aggregation round needs two sets of input:
+///  * computed proofs from the previous round
+///  * some artifacts that the witness generator of previous round(s) returns.
+///
+/// There are four rounds of proofs for every block,
+/// each of them starts with an invocation of `WitnessGenerator` with a corresponding `WitnessGeneratorJobType`:
+///  * `WitnessGeneratorJobType::BasicCircuits`:
+///         generates basic circuits (circuits like `Main VM` - up to 50 * 48 = 2400 circuits):
+///         input table: `basic_circuit_witness_jobs`
+///         artifact/output table: `leaf_aggregation_jobs` (also creates job stubs in `node_aggregation_jobs` and `scheduler_aggregation_jobs`)
+///         value in `aggregation_round` field of `prover_jobs` table: 0
+///  * `WitnessGeneratorJobType::LeafAggregation`:
+///         generates leaf aggregation circuits (up to 48 circuits of type `LeafAggregation`)
+///         input table: `leaf_aggregation_jobs`
+///         artifact/output table: `node_aggregation_jobs`
+///         value in `aggregation_round` field of `prover_jobs` table: 1
+///  * `WitnessGeneratorJobType::NodeAggregation`
+///         generates one circuit of type `NodeAggregation`
+///         input table: `leaf_aggregation_jobs`
+///         value in `aggregation_round` field of `prover_jobs` table: 2
+///  * scheduler circuit
+///         generates one circuit of type `Scheduler`
+///         input table: `scheduler_witness_jobs`
+///         value in `aggregation_round` field of `prover_jobs` table: 3
+///
+/// One round of prover generation consists of:
+///  * `WitnessGenerator` picks up the next `queued` job in its input table and processes it
+///         (invoking the corresponding helper function in `zkevm_test_harness` repo)
+///  * it saves the generated circuis to `prover_jobs` table and the other artifacts to its output table
+///  * the individual proofs are picked up by the provers, processed, and marked as complete.
+///  * when the last proof for this round is computed, the prover updates the row in the output table
+///    setting its status to `queued`
+///  * `WitnessGenerator` picks up such job and proceeds to the next round
+///
+/// Note that the very first input table (`basic_circuit_witness_jobs`)
+/// is populated by the tree (as the input artifact for the `WitnessGeneratorJobType::BasicCircuits` is the merkle proofs)

+
+/// Implementation of the test/fake connection pool to be used in tests.
+/// This implementation works over an established transaction in order to reject
+/// any changes made to the database, even if the tested component initiates and commits
+/// its own transactions.
+///
+/// ## How does it work
+///
+/// Test pool uses an established transaction to be created. This transaction, in its turn,
+/// is used to establish a *subtransaction*. Reference to this subtransaction will be used
+/// as a connection to create `StorageProcessor` objects in test.
+///
+/// Having a subtransaction is necessary: even if some component will (mistakenly) will not
+/// initiate a transaction and will call `commit` on `StorageProcessor`, changes won't be
+/// persisted, since top-level transaction will be dropped.
+///
+/// At the same time, using *reference* to the subtransaction in created `StorageProcessor`
+/// objects is also necessary: upon `drop`, transaction gets discarded. It means that if we
+/// use transaction and somewhere in test `StorageProcessor` is created, used without
+/// transaction and then dropped (which is a normal use case for e.g. test setup) -- such
+/// changes would be discarded and test will not execute correctly.
+///
+/// ## Safety
+///
+/// Test pool relies on unsafe code to work, so it comes with several invariants to be
+/// upheld by its user. They are *not* enforced by compiler and breaking *any* of them
+/// will result in undefined behavior.
+///
+/// Usage invariants:
+/// - This object should never outlive the transaction used to create it. If, for example,
+///   test pool is created and passed to another thread and the thread with the original
+///   connection panics (or connection is simply dropped), the behavior is undefined.
+/// - Concurrent access to the pool is forbidden. `TestPool` has to be `Sync` in order to
+///   not break the interface of the `ConnectionPool`, but since it operates over a single
+///   established transaction, it can't be safely accessed from multiple threads.
+///   Moving the object to another thread is safe though.
+/// - Since we use mutable reference to the subtransaction to create `StorageProcessor`, you
+///   should not create and use multiple `StorageProcessor` objects in the same scope.
+///
+/// This object is meant to be used in unit tests only, any attempt to use it with the real
+/// database is on the conscience of the user. I have warned you.

+//! This file is a copy-paste from https://github.com/tomusdrw/rust-web3/blob/master/src/api/accounts.rs#L39
+//! We want to use our own Signer, which is independent of Transaction Sender.
+//! Unfortunately, it is impossible to use public interfaces from web3 library.
+//! The only thing which has been changed is optional parameters, which are necessary for signing transactions.
+//! In the library, they are filling using eth_node.
+//!
+//! I see no big difference between transaction and transaction parameters.
+//! We can refactor this code and adapt it for our needs better, but I prefer to reuse as much code as we can.
+//! In the case where it will be possible to use only the web3 library without copy-paste, the changes will be small and simple

+//! Utilities to efficiently pack pubdata (aka storage access slots).
+//!
+//! Overall the idea is following:
+//! If we have a type with at most X bytes, and *most likely* some leading bytes will be
+//! zeroes, we can implement a simple variadic length encoding, compressing the type
+//! as <length><data>. In case of `uint32` it will allow us to represent number
+//! `0x00000022` as `0x0122`. First byte represents the length: 1 byte. Second byte represents
+//! the value itself. Knowledge about the type of encoded value is implied: without such a knowledge,
+//! we wouldn't be able to parse pubdata at all.
+//!
+//! Drawbacks of such an approach are the following:
+//!
+//! - In case of no leading zeroes, we spend one more byte per value. This one is a minor, because as long
+//!   as there are more values which *have* leading zeroes, we don't lose anything.
+//! - We use complex access keys which may have two components: 32-bit writer ID + 256-bit key, and encoding this
+//!   pair may be actually longer than just using the hash (which represents the actual key in the tree).
+//!   To overcome this drawback, we will make the value `0xFF` of the length byte special: this value means that instead
+//!   of packed key fields we have just an unpacked final hash. At the time of packing we will generate both forms
+//!   and choose the shorter one.

+# Loadnext: the next generation loadtest for zkSync
+
+Loadnext is an utility for random stress-testing the zkSync server. It is capable of simulating the behavior of many
+independent users of zkSync network, who are sending quasi-random requests to the server.
+
+It:
+
+- doesn't care whether the server is alive or not. At worst, it will just consider the test failed. No panics, no
+  mindless unwraps, yay.
+- does a unique set of operations for each participating account.
+- sends transactions and priority operations.
+- sends incorrect transactions as well as correct ones and compares the outcome to the expected one.
+- has an easy-to-extend command system that allows adding new types of actions to the flow.
+- has an easy-to-extend report analysis system.
+
+Flaws:
+
+- It does not send API requests other than required to execute transactions.
+- So far it has pretty primitive report system.
+
+## Launch
+
+In order to launch the test in the development scenario, you must first run server and prover (it is recommended to use
+dummy prover), and then launch the test itself.
+
+```sh
+# First terminal
+zk server
+# Second terminal
+RUST_BACKTRACE=1 RUST_LOG=info,jsonrpsee_ws_client=error cargo run --bin loadnext
+```
+
+Without any configuration supplied, the test will fallback to the dev defaults:
+
+- Use one of the "rich" accounts in the private local Ethereum chain.
+- Use a random ERC-20 token from `etc/tokens/localhost.json`.
+- Connect to the localhost zkSync node and use localhost web3 API.
+
+**Note:** when running the loadtest in the localhost scenario, you **must** adjust the supported block chunks sizes.
+Edit the `etc/env/dev/chain.toml` and set `block_chunk_sizes` to `[10,32,72,156,322,654]` and `aggregated_proof_sizes`
+to `[1,4,8,18]`. Do not forget to re-compile configs after that.
+
+This is required because the loadtest relies on batches, which will not fit into smaller block sizes.
+
+## Configuration
+
+For cases when loadtest is launched outside of the localhost environment, configuration is provided via environment
+variables.
+
+The following variables are required:
+
+```sh
+# Address of the Ethereum web3 API.
+L1_RPC_ADDRESS
+# Ethereum private key of the wallet that has funds to perform a test (without `0x` prefix).
+MASTER_WALLET_PK
+# Amount of accounts to be used in test.
+# This option configures the "width" of the test:
+# how many concurrent operation flows will be executed.
+ACCOUNTS_AMOUNT
+# All of test accounts get split into groups that share the
+# deployed contract address. This helps to emulate the behavior of
+# sending `Execute` to the same contract and reading its events by
+# single a group. This value should be less than or equal to `ACCOUNTS_AMOUNT`.
+ACCOUNTS_GROUP_SIZE
+# Amount of operations per account.
+# This option configures the "length" of the test:
+# how many individual operations each account of the test will execute.
+OPERATIONS_PER_ACCOUNT
+# Address of the ERC-20 token to be used in test.
+#
+# Token must satisfy two criteria:
+# - Be supported by zkSync.
+# - Have `mint` operation.
+#
+# Note that we use ERC-20 token since we can't easily mint a lot of ETH on
+# Rinkeby or Ropsten without caring about collecting it back.
+MAIN_TOKEN
+# Path to test contracts bytecode and ABI required for sending
+# deploy and execute L2 transactions. Each folder in the path is expected
+# to have the following structure:
+# .
+# ├── bytecode
+# └── abi.json
+# Contract folder names names are not restricted.
+# An example:
+# .
+# ├── erc-20
+# │   ├── bytecode
+# │   └── abi.json
+# └── simple-contract
+#     ├── bytecode
+#     └── abi.json
+TEST_CONTRACTS_PATH
+# Limits the number of simultaneous API requests being performed at any moment of time.
+#
+# Setting it to:
+# - 0 turns off API requests.
+# - `ACCOUNTS_AMOUNT` relieves the limit.
+SYNC_API_REQUESTS_LIMIT
+# zkSync Chain ID.
+L2_CHAIN_ID
+# Address of the zkSync web3 API.
+L2_RPC_ADDRESS
+```
+
+Optional parameters:
+
+```sh
+# Optional seed to be used in the test: normally you don't need to set the seed,
+# but you can re-use seed from previous run to reproduce the sequence of operations locally.
+# Seed must be represented as a hexadecimal string.
+SEED
+```
+
+## Infrastructure relationship
+
+This crate is meant to be independent of the existing zkSync infrastructure. It is not integrated in `zk` and does not
+rely on `zksync_config` crate, and is not meant to be.
+
+The reason is that this application is meant to be used in CI, where any kind of configuration pre-requisites makes the
+tool harder to use:
+
+- Additional tools (e.g. `zk`) must be shipped together with the application, or included into the docker container.
+- Configuration that lies in files is harder to use in CI, due some sensitive data being stored in GITHUB_SECRETS.

+///
+/// Report collector by its nature only receives reports and uses different collectors in order to analyze them.
+/// Currently, only the following collectors are used:
+///
+/// - MetricsCollector, which builds time distribution histograms for each kind of performed action.
+/// - OperationResultsCollector, a primitive collector that counts the amount of failures and decides whether
+///   test is passed.
+///
+/// Other possible collectors that can be implemented:
+///
+/// - ScriptCollector, which records all the actions (including wallet private keys and signatures), which makes it
+///   possible to reproduce test once again.
+/// - RetryCollector, which analyzes the average amount of retries that have to be made in order to make operation
+///   succeed.
+/// - PrometheusCollector, which exposes the ongoing loadtest results to grafana via prometheus.
+///
+/// Note that if you'll decide to implement a new collector, be sure that adding an entry in it is cheap: if you want
+/// to do some IO (file or web), it's better to divide collector in two parts: an actor which receives commands through

+//! Gas price test is used to calculate costs of user transactions in terms of gas price.

+//! as a sanity check after contract refactoring.
+//!
+//! It is important for several reasons:
+//! * Transfer cost determines maximum possible TPS of our network in larger block size limit.
+//! * Cost of operations in the verify functions could stop block verification because of the block gas limit.
+//! * It is useful to calculate cost of the "griefing" attack.

+# NFTF -- New Fancy Test Framework
+
+This folder contains a framework for writing integration tests for zkSync Era, as well as set of integration test
+suites.
+
+This framework is built atop of [jest](https://jestjs.io/). It is _highly recommended_ to familiarize yourself with its
+documentation to be able to write tests.
+
+## Features
+
+- Separated framework/tests logic.
+- Parallel test suite execution.
+- Ability to run tests concurrently within one suite.
+- Custom matchers & helpers.
+- Automated used funds recollection.
+
+### Test run lifecycle
+
+Before starting any test, framework would analyze `tests` folder to pick up all the test suites we have, and then will
+prepare the context for tests. Context initialization consists of:
+
+- Waiting for server to start.
+- Creating personal accounts for each test suite.
+- Providing funds to these accounts.
+
+Basically, during initialization, everything is prepared for writing tests that interact with zkSync.
+
+After that, each test suite is ran _in parallel_. Each test suite can claim its own account and be sure that this
+account has funds on it and is not used by any other suite.
+
+After all the test suites are completed, funds from all the used accounts are recollected and sent back to the main
+account used to setup the test.
+
+### Sample test suite
+
+To create a new test suite, you just need to create a file named `<whatever>.test.ts` in the `tests` directory.
+
+Sample test suite would look like this:
+
+```typescript
+/**
+ * This suite contains tests checking our handling of Ether (such as depositing, checking `msg.value`, etc).
+ */
+
+import { TestMaster } from '../src/index';
+import { shouldChangeETHBalances } from '../src/matchers/transaction-modifiers';
+
+import * as zksync from 'zksync-web3';
+import { BigNumber } from 'ethers';
+
+describe('ETH token checks', () => {
+  let testMaster: TestMaster;
+  let alice: zksync.Wallet;
+  let bob: zksync.Wallet;
+
+  beforeAll(() => {
+    // Test master is an interface to access prefunded account.
+    testMaster = TestMaster.getInstance(__filename);
+    // ...through it you can obtain a personal funded account.
+    alice = testMaster.mainAccount();
+    // ...and an unlimited amount of empty ones.
+    bob = testMaster.newEmptyAccount();
+  });
+
+  test('Can perform a transfer', async () => {
+    const value = BigNumber.from(200);
+
+    // Declare modifier to check that ETH balances would change in the following way.
+    const ethBalanceChange = await shouldChangeETHBalances([
+      { wallet: alice, change: -value },
+      { wallet: bob, change: value }
+    ]);
+
+    // Send transfer, it should succeed. Apply a modifier we declared above.
+    await expect(alice.sendTransaction({ to: bob.address, value })).toBeAccepted([ethBalanceChange]);
+  });
+
+  afterAll(async () => {
+    // It will collect all the funds from temporary accounts back.
+    await testMaster.deinitialize();
+  });
+});
+```
+
+### Custom matchers
+
+One of the big features of this framework is the ability to create custom matchers to not duplicate the checking logic
+that is used in multiple tests.
+
+To see documentation on the matchers available by default, see the [jest documentation](https://jestjs.io/docs/expect).
+To see documentation on the custom matchers of this framework, see [the type definitions file](./typings/jest.d.ts).
+
+To declare your own matcher, look at [existing matchers](./src/matchers/) and use them as an example. Once matchers are
+implemented, register them at [setup file](./src/jest-setup/add-matchers.ts) and add type declarations to the
+[typings file](./typings/jest.d.ts). Don't forget to add documentation for the matcher!
+
+### Matcher modifiers
+
+`toBeAccepted` and `toBeRejected` matchers accept modifiers. You can see one (`shouldChangeETHBalances`) above. There
+are others (like `shouldChangeTokenBalances` or `shouldOnlyTakeFee`), and if needed you can create your onw ones.
+
+These modifiers would be applied to the transaction receipt, and you can implement any kind of custom logic there. To do
+so, you just need to declare a class that inherits `MatcherModifier` class and implements the `check` method.
+
+For more details on the interface, see the
+[transaction-modifiers.ts](./src/transaction-matcher-modifiers/transaction-modifiers.ts).
+
+Note: you don't have to always declare modifiers there. If your modifier is specific to one suite only, you can declare
+it right there and use in your tests.
+
+## Helpers
+
+For common actions like deploying a contract or transferring funds, a set of helpers is provided. These helpers can be
+found in the [corresponding file](./src/helpers.ts).
+
+Feel free to add new functionality there if it'll be used by multiple test suites. If the logic is exclusive for just
+one test suite, you may declare your own helper functions right in the suite file.
+
+## Debug logging
+
+During context initialization and teardown you can enable showing the debug logs to troubleshoot issues. To do so, run
+tests with the `ZKSYNC_DEBUG_LOGS` environment variable set.
+
+To add more logs to the context initialization, use `reporter` object in the `ContextOwner` class. Example:
+
+```typescript
+this.reporter.debug(`Some useful info`);
+```
+
+## Fast and long modes
+
+Some integration tests may be very long to run in real environment (e.g. stage). Namely, tests that wait for the block
+finalization: it make take several hours to generate a proof and send it onchain.
+
+Because of that, framework supports "fast" and "long" modes. `TestMaster` objects have `isFastMode` method to determine
+which mode is currently being used.
+
+If you're going to write a test that can make test run duration longer, it is adviced to guard the "long" part with the
+corresponding check.
+
+By default, "long" mode is assumed, and to enable the "fast" mode one must set the `ZK_INTEGRATION_TESTS_FAST_MODE`
+environment variable to `true`.
+
+## Helpful patterns
+
+### Checking promise and then using it
+
+Sometimes you need to check promise in a matcher, but then you need to actually use the resolved result. Solution: in
+JS/TS it's OK to await the promise twice.
+
+You can do it as follows:
+
+```typescript
+// Create promise
+const withdrawalPromise = alice.withdraw({ token: zksync.utils.ETH_ADDRESS, amount });
+// Here you use promise in the matcher.
+await expect(withdrawalPromise).toBeAccepted([l2ethBalanceChange]);
+// And here you retrieve its value. It's OK to await same promise twice.
+const withdrawalTx = await withdrawalPromise;
+await withdrawalTx.waitFinalize();
+```
+
+### Focus on what you're checking
+
+Don't try to put all the checks in the world to your test.
+
+For example: If you need to do a transfer, and we already have a test for transfers, you don't need to check if it
+succeeds. Every failed transaction would throw an error and fail the tests, and the exact test for transfers would show
+the cause in this case.
+
+Focus on what you need to check. Assume that all the prerequisites for that work as expected. Keep the tests short and
+simple.
+
+## Big DONTs
+
+To avoid the test suite becoming a mess, please DON'T:
+
+- Test more than one thing in one `test` block. Tests should be short and check the thing that is written in its
+  description.
+- Duplicate test logic in multiple tests. If you need to check the same thing twice, try to implement a matcher instead.
+- Add tests that don't match suite logic. If your test (or tests) check something that is nor strictly related to the
+  topic of suite, create a new suite instead. Suites are being run in parallel, and we should use this fact.
+- Perform L1 operations if not strictly required. Depositing and waiting for finalization are operations that take a lot
+  of time, especially on stage. It should be avoided, and if it can't be avoided, try to optimize tests so that less
+  time is spent waiting without any actions.
+- Create accounts yourself. Framework recollects used funds back after the execution, so the only right way to create a
+  new wallet is through `TestMaster`.
+- Rely on things that you don't control. For example, balance of the fee account: multiple transactions may affect it in
+  parallel, so don't expect it to have the exact value.

+/**
+ * This class is responsible for preparing the test environment for all the other test suites.
+ *
+ * ## Context initialization
+ *
+ * To enable test suites to do their checks, this class:
+ * - Waits for server to launch (required for running tests on stage right after deployment).
+ * - Ensures that "master" wallet has enough balances to perform the tests.
+ * - Prepares wallets for each test suite and adds funds to them.
+ * - Deploys the test contracts.
+ *
+ * ## Performed checks
+ *
+ * Given the fact that all the test suites would be run in parallel, while context initialization
+ * is performed sequentially, during initialization this class also performs several basic "sanity"
+ * checks (e.g. "ether transfers works" and "fees are being collected").
+ * Checks performed by this class should belong to one of the following categories:
+ * 1) It's a "building block" for other tests (e.g., if contract deployments don't work, other test suites won't work as well).
+ * 2) It must be run sequentially (e.g. it's hard to ensure that fee account received exact amount of fee if multiple processes
+ *    send transactions).
+ *
+ * Important!
+ * Only add the essential checks to this class, as it should be kept minimal. Whenever possible, prefer creating a new test suite
+ * or extending an existing one.

+# zkSync v2 Project Architecture
+
+This document will help you answer the question: _where can I find the logic for x?_ by giving a directory-tree style
+structure of the physical architecture of the zkSync Era project.
+
+## High-Level Overview
+
+The zksync-2-dev repository has the following main units:
+
+<ins>**Smart Contracts:**</ins> All the smart contracts in charge of the protocols on the L1 & L2. Some main contracts:
+
+- L1 & L2 bridge contracts.
+- The zkSync rollup contract on Ethereum.
+- The L1 proof verifier contract.
+
+**<ins>Core App:**</ins> The execution layer. A node running the zkSync network in charge of the following components:
+
+- Monitoring the L1 smart contract for deposits or priority operations.
+- Maintaining a mempool that receives transactions.
+- Picking up transactions from the mempool, executing them in a VM, and changing the state accordingly.
+- Generating zkSync chain blocks.
+- Preparing circuits for executed blocks to be proved.
+- Submitting blocks and proofs to the L1 smart contract.
+- Exposing the Ethereum-compatible web3 API.
+
+**<ins>Prover App:**</ins> The prover app takes blocks and metadata generated by the server and constructs a validity zk
+proof for them.
+
+**<ins>Storage Layer:**</ins> The different components and subcomponents don't communicate with each other directly via
+APIs, rather via the single source of truth -- the db storage layer.

+# Development guide
+
+This document covers development-related actions in zkSync.
+
+## Initializing the project
+
+To setup the main toolkit, `zk`, simply run:
+
+```
+zk
+```
+
+You may also configure autocompletion for your shell via:
+
+```
+zk completion install
+```
+
+Once all the dependencies were installed, project can be initialized:
+
+```
+zk init
+```
+
+This command will do the following:
+
+- Generate `$ZKSYNC_HOME/etc/env/dev.env` file with settings for the applications.
+- Initialize docker containers with `geth` Ethereum node for local development.
+- Download and unpack files for cryptographical backend.
+- Generate required smart contracts.
+- Compile all the smart contracts.
+- Deploy smart contracts to the local Ethereum network.
+- Create “genesis block” for server.
+
+Initializing may take pretty long, but many steps (such as downloading & unpacking keys and initializing containers) are
+required to be done only once.
+
+Usually, it is a good idea to do `zk init` once after each merge to the `main` branch (as application setup may change).
+
+Additionally, there is a subcommand `zk clean` to remove previously generated data. Examples:
+
+```
+zk clean --all # Remove generated configs, database and backups.
+zl clean --config # Remove configs only.
+zk clean --database # Remove database.
+zk clean --backups # Remove backups.
+zk clean --database --backups # Remove database *and* backups, but not configs.
+```
+
+**When do you need it?**
+
+1. If you have an initialized database and want to run `zk init`, you have to remove the database first.
+2. If after getting new functionality from the `main` branch your code stopped working and `zk init` doesn't help, you
+   may try removing `$ZKSYNC_HOME/etc/env/dev.env` and running `zk init` once again. This may help if the application
+   configuration has changed.
+
+If you don’t need all of the `zk init` functionality, but just need to start/stop containers, use the following
+commands:
+
+```
+zk up   # Set up `geth` container
+zk down # Shut down `geth` container
+```
+
+## Reinitializing
+
+When actively changing something that affects infrastructure (for example, contracts code), you normally don't need the
+whole `init` functionality, as it contains many external steps (e.g. deploying ERC20 tokens) which don't have to be
+redone.
+
+For this case, there is an additional command:
+
+```
+zk reinit
+```
+
+This command does the minimal subset of `zk init` actions required to "reinitialize" the network. It assumes that
+`zk init` was called in the current environment before. If `zk reinit` doesn't work for you, you may want to run
+`zk init` instead.
+
+## Committing changes
+
+`zksync` uses pre-commit and pre-push git hooks for basic code integrity checks. Hooks are set up automatically within
+the workspace initialization process. These hooks will not allow to commit the code which does not pass several checks.
+
+Currently the following criteria are checked:
+
+- Rust code should always be formatted via `cargo fmt`.
+- Other code should always be formatted via `zk fmt`.
+- Dummy Prover should not be staged for commit (see below for the explanation).
+
+## Using Dummy Prover
+
+By default, the chosen prover is a "dummy" one, meaning that it doesn't actually compute proofs but rather uses mocks to
+avoid expensive computations in the development environment.
+
+To switch dummy prover to real prover, one must change `dummy_verifier` to `false` in `contracts.toml` for your env
+(most likely, `etc/env/dev/contracts.toml`) and run `zk init` to redeploy smart contracts.
+
+## Testing
+
+- Running the `rust` unit-tests:
+
+  ```
+  zk test rust
+  ```
+
+- Running a specific `rust` unit-test:
+
+  ```
+  zk test rust --package <package_name> --lib <mod>::tests::<test_fn_name> -- --exact
+  # e.g. zk test rust --package zksync_core --lib eth_sender::tests::resend_each_block -- --exact
+  ```
+
+- Running the integration test:
+
+  ```
+  zk server           # Has to be run in the 1st terminal
+  zk test i server    # Has to be run in the 2nd terminal
+  ```
+
+- Running the benchmarks:
+
+  ```
+  zk f cargo bench
+  ```
+
+- Running the loadtest:
+
+  ```
+  zk server # Has to be run in the 1st terminal
+  zk prover # Has to be run in the 2nd terminal if you want to use real prover, otherwise it's not required.
+  zk run loadtest # Has to be run in the 3rd terminal
+  ```
+
+## Contracts
+
+### Re-build contracts
+
+```
+zk contract build
+```
+
+### Publish source code on etherscan
+
+```
+zk contract publish
+```

+# Running the application
+
+This document covers common scenarios of launching zkSync applications set locally.
+
+## Prerequisites
+
+Prepare dev environment prerequisites: see
+
+[Installing dependencies](./setup-dev.md)
+
+## Setup local dev environment
+
+Setup:
+
+```
+zk # installs and builds zk itself
+zk init
+```
+
+During the first initialization you have to download around 8 GB of setup files, this should be done once. If you have a
+problem on this step of the initialization, see help for the `zk run plonk-setup` command.
+
+If you face any other problems with the `zk init` command, go to the [Troubleshooting](##Troubleshooting) section at the
+end of this file. There are solutions for some common error cases.
+
+To completely reset the dev environment:
+
+- Stop services:
+
+  ```
+  zk down
+  ```
+
+- Repeat the setup procedure above
+
+If `zk init` has already been executed, and now you only need to start docker containers (e.g. after reboot), simply
+launch:
+
+```
+zk up
+```
+
+## (Re)deploy db and contracts
+
+```
+zk contract redeploy
+```
+
+## Environment configurations
+
+Env config files are held in `etc/env/`
+
+List configurations:
+
+```
+zk env
+```
+
+Switch between configurations:
+
+```
+zk env <ENV_NAME>
+```
+
+Default configuration is `dev.env`, which is generated automatically from `dev.env.example` during `zk init` command
+execution.
+
+## Build and run server
+
+Run server:
+
+```
+zk server
+```
+
+Server is configured using env files in `./etc/env` directory. After the first initialization, file
+`./etc/env/dev.env`will be created. By default, this file is copied from the `./etc/env/dev.env.example` template.
+
+Make sure you have environment variables set right, you can check it by running: `zk env`. You should see `* dev` in
+output.

+# Installing dependencies
+
+## Supported operating systems
+
+zkSync is currently can be launched on any \*nix operating system (e.g. any linux distribution or MacOS).
+
+If you're using Windows, then make sure to use WSL 2, since WSL 1 is known to cause troubles.
+
+Additionally, if you are going to use WSL 2, make sure that your project is located in the _linux filesystem_, since
+accessing NTFS partitions from inside of WSL is very slow.
+
+## `Docker`
+
+Install `docker`. It is recommended to follow the instructions from the
+[official site](https://docs.docker.com/install/).
+
+Note: currently official site proposes using Docker Desktop for linux, which is a GUI tool with plenty of quirks. If you
+want to only have CLI tool, you need the `docker-ce` package and you can follow
+[this guide](https://www.digitalocean.com/community/tutorials/how-to-install-and-use-docker-on-ubuntu-20-04) for Ubuntu.
+
+Installing `docker` via `snap` or from the default repository can cause troubles.
+
+You need to install both `docker` and `docker-compose`.
+
+**Note:** `docker-compose` is installed automatically with `Docker Desktop`.
+
+**Note:** On linux you may encounter the following error when you’ll try to work with `zksync`:
+
+```
+ERROR: Couldn't connect to Docker daemon - you might need to run `docker-machine start default`.
+```
+
+If so, you **do not need** to install `docker-machine`. Most probably, it means that your user is not added to
+the`docker` group. You can check it as follows:
+
+```bash
+docker-compose up # Should raise the same error.
+sudo docker-compose up # Should start doing things.
+```
+
+If the first command fails, but the second succeeds, then you need to add your user to the `docker` group:
+
+```bash
+sudo usermod -a -G docker your_user_name
+```
+
+After that, you should logout and login again (user groups are refreshed after the login). The problem should be solved
+at this step.
+
+If logging out does not help, restarting the computer should.
+
+## `Node` & `Yarn`
+
+1. Install `Node` (requires version 14.14.0). Since our team attempts to always use the latest LTS version of`Node.js`,
+   we suggest you to install [nvm](https://github.com/nvm-sh/nvm). It will allow you to update `Node.js`version easily
+   in the future.
+2. Install `yarn`. Instructions can be found on the [official site](https://classic.yarnpkg.com/en/docs/install/). Check
+   if `yarn` is installed by running `yarn -v`. If you face any problems when installing `yarn`, it might be the case
+   that your package manager installed the wrong package.Make sure to thoroughly follow the instructions above on the
+   official website. It contains a lot of troubleshooting guides in it.
+
+## `Axel`
+
+Install `axel` for downloading keys:
+
+On mac:
+
+```bash
+brew install axel
+```
+
+On debian-based linux:
+
+```bash
+sudo apt-get install axel
+```
+
+Check the version of `axel` with the following command:
+
+```
+axel --version
+```
+
+Make sure the version is higher than `2.17.10`.
+
+## `clang`
+
+In order to compile RocksDB, you must have LLVM available. On debian-based linux it can be installed as follows:
+
+On linux:
+
+```bash
+sudo apt-get install build-essential pkg-config cmake clang lldb lld
+```
+
+On mac:
+
+You need to have an up-to-date `Xcode`. You can install it directly from `App Store`. With Xcode command line tools, you
+get the Clang compiler installed by default. Thus, having XCode you don't need to install `clang`.
+
+## `OpenSSL`
+
+Install OpenSSL:
+
+On mac:
+
+```bash
+brew install openssl
+```
+
+On linux:
+
+```bash
+sudo apt-get install libssl-dev
+```
+
+## `Rust`
+
+Install the latest `rust` version.
+
+Instructions can be found on the [official site](https://www.rust-lang.org/tools/install).
+
+Verify the `rust` installation:
+
+```bash
+rustc --version
+rustc 1.xx.y (xxxxxx 20xx-yy-zz) # Output may vary depending on actual version of rust
+```
+
+### Postgres
+
+Install the latest postgres.
+
+```bash
+brew install postgresql
+```
+
+### SQLx CLI
+
+SQLx is a Rust library we use to interact with Postgres, and its CLI is used to manage DB migrations and support several
+features of the library.
+
+```bash
+cargo install sqlx-cli --version 0.5.13
+```
+
+## Environment
+
+Edit the lines below and add them to your shell profile file (e.g. `~/.bash_profile`, `~/.zshrc`):
+
+```bash
+# Add path here:
+export ZKSYNC_HOME=/path/to/zksync
+
+export PATH=$ZKSYNC_HOME/bin:$PATH
+
+# If you're like me, uncomment:
+# cd $ZKSYNC_HOME
+```
+
+### Tip: `mold`
+
+Optionally, you may want to optimize the build time with the modern linker, [`mold`](https://github.com/rui314/mold).
+
+This linker will speed up the build times, which can be pretty big for Rust binaries.
+
+Follow the instructions in the repo in order to install it and enable for Rust.
+
+## Tip: Speeding up building `RocksDB`
+
+By default, each time you compile `rocksdb` crate, it will compile required C++ sources from scratch. It can be avoided
+by using precompiled versions of library, and it will significantly improve your build times.
+
+In order to do so, you can put compiled libraries to some persistent location, and add the following to your shell
+configuration file (e.g. `.zshrc` or `.bashrc`):
+
+```
+export ROCKSDB_LIB_DIR=<library location>
+export SNAPPY_LIB_DIR=<library location>
+```
+
+Make sure that compiled libraries match the current version of RocksDB. One way to obtain them, is to compile the
+project in the usual way once, and then take built libraries from
+`target/{debug,release}/build/librocksdb-sys-{some random value}/out`.

+# Base configuration for zkSync stack
+
+This folder contains the template for generating the configuration for zkSync applications. Configs in this folder are
+assigned default values suitable for the development.
+
+Since all the applications expect configuration to be set via the environment variables, these configs are compiled into
+one `*.env` file, which will be loaded prior to the application launch.
+
+Configuration files can be compiled with the `zk` subcommand:
+
+```sh
+zk config compile
+```
+
+Without any additional arguments specified, this subcommand will do the following:
+
+1. Check whether `etc/env/current` file exists. If so, it is read and the name of the current environment is taken from
+   there. Otherwise, the environment is assumed to be called `dev`.
+2. Check whether the folder with the name same as current environment exists. If so, configs are read from there.
+   Otherwise behavior depends on the environment name: for `dev` environment, `dev` folder will be created as a copy of
+   the `base` folder. For any other environment, an error will be reported.
+3. `zk` will iterate through all the `toml` files and load specified values. Once all the data is loaded, a new file
+   named `<environment>.dev` is created and all the values are placed there.
+
+It is possible to specify the config you want to compile:
+
+```sh
+zk config compile testnet # Will compile configs for the `testnet` environment.
+```

+- `constant`: Data that remains the same between various runs, filled manually and committed to the repository. For
+  example, private / public keys of test accounts.
+- `volatile`: Data that may change, filled by scripts and is **not** committed to the repository. For example, deployed
+  contracts addresses.
+- `sdk`: Data used to test SDK implementations.

+# `zk`
+
+### Scope
+
+This document describes how to extend the `zk` tool. For usage tips please use `--help` flag available on all
+subcommands.
+
+### Adding a top-level subcommand
+
+To add a top-level subcommand `cmd` follow these steps:
+
+- create a file `src/cmd.ts`
+- implement all needed functionality (preferably export it, too)
+- create an `export const command` via [`commander.js`](https://github.com/tj/commander.js) API, possibly extending
+  itself with subcommands
+- declare `import { command as cmd } from './cmd';` in `src/index.ts`
+- add `cmd` as a subcommand via `.addCommand(cmd)`
+- notify the team to rebuild `zk` upon merge
+
+If `cmd` will have deeply nested subcommands, consider creating a directory `cmd/` instead of a file. See `db/`
+structure as an example.
+
+### Extending an existing subcommand
+
+Simply add the needed functionality to the corresponding `.ts` file and add your subcommand to the existing
+`const command` via `.command(...)` API. Don't forget to notify the team to rebuild `zk` upon merge.
+
+### Building changes
+
+Simply run `zk` which will `yarn build` the changes for you!
