Getting started with ZKsync

Installation

To get started with ZKsync on moccasin, you’ll need the following:

  • era_test_node

    • You’ll know you did it right if you can run era_test_node --version and you see a response like era_test_node 0.1.0 (a178051e8 2024-09-07)

  • era-compiler-vyper

    • You’ll know you did it right if you can run zkvyper --version and you see a response like Vyper compiler for ZKync v1.5.4 (LLVM build f9f732c8ebdb88fb8cd4528482a00e4f65bcb8b7)

Testing

To test on a local ZKsync network, run the following:

mox test --network eravm

And you’ll spin up a local ZKsync network and run your tests on it! You can then deploy, test, and verify contracts as you would any other network.

Note

As of today, moccasin does not support “system contracts” or “simulations”; therefore, testing things like native account abstraction is not yet supported. You can “do” them, but they will require custom scaffolding.

Deployment

To deploy to a ZKsync network, you have to do a lot of work.

1. Setup your network

[networks.sepolia-zksync]
url = "$SEPOLIA_ZKSYNC_RPC_URL"
is_zksync = true

  1. Run your script

mox run deploy.py --network sepolia-zksync

That’s it! moccasin can handle ZKsync networks like any other.
