📋 Summary

The latest version of [email protected], introduces a significant architectural overhaul compared to its previous releases, enhancing its compatibility and integration with zkSync environments. Here's a summary of the key changes:

• Compilation: Utilizes solc and zksolc for bytecode generation, managed under DualCompiledContract via an Executor and CheatcodeTracer for improved debugging.
• EVM Interactions: Maintains standard EVM calls with adaptations for address.balance and block.timestamp/block.number to source data from zkSync's storage, ensuring consistency.
• Transaction Handling: Transforms CALL and CREATE operations into zkSync transactions, including bytecode retrieval, nonce management, and EOA marking to align with zkSync protocols.
• Execution and State Management: Processes transactions through the zkSync VM, applying state changes to journaled_state, with results communicated back for verification.
• Integration and Usage: Enables zkSync features in forge with the --zksync flag and in tests via vm.zkVm(true), phasing out zkforge and zkcast for a unified toolset.

This update streamlines zkSync environment development, offering simplified command usage and enhanced compatibility.
