ZKsync Era is a layer 2 rollup that uses zero-knowledge proofs to scale Ethereum without compromising on security or decentralization. As it's EVM-compatible (with Solidity/Vyper), 99% of Ethereum projects can redeploy without needing to refactor or re-audit any code. ZKsync Era also uses an LLVM-based compiler that will eventually enable developers to write smart contracts in popular languages such as C++ and Rust.
The era-evm-tester test framework runs tests for EVM implementation on top of EraVM.
1. Install Rust.
-
Follow the latest official instructions:
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh . ${HOME}/.cargo/env
Currently we are not pinned to any specific version of Rust, so just install the latest stable build for your platform.
2. Install ZKsync Foundry.
- Follow the latest instructions from ZKsync Foundry Book
3. Checkout or clone the repository.
-
If you have not cloned this repository yet:
git clone https://github.com/matter-labs/era-evm-tester.git --recursive
-
If you have already cloned this repository:
git submodule update --init --recursive --remote
4. Build system contracts.
-
Install Node.js
-
Enter system contracts directory:
cd era-contracts -
Install dependencies:
yarn
-
Build contracts:
yarn build
When the build succeeds, you can run the tests using the usage section.
- EVM emulator on top of EraVM
Each command assumes you are at the root of the evm-tester repository.
cargo run --release --bin evm-tester -- [-v] \
[--path="${PATH}"]*There are more rarely used options, which you may check out with ./target/release/evm-tester --help.

ZKsync Era has been through extensive testing and audits, and although it is live, it is still in alpha state and will undergo further audits and bug bounty programs. We would love to hear our community's thoughts and suggestions about it! It's important to note that forking it now could potentially lead to missing important security updates, critical features, and performance improvements.
