foundry-devops

A repo to get the most recent deployment from a given environment in foundry. This way, you can do scripting off previous deployments in solidity.

It will look through your broadcast folder at your most recent deployment.

Features

• Get the most recent deployment of a contract in foundry
• Checking if you're on a zkSync based chain

Getting Started

Installation

forge install Cyfrin/foundry-devops --no-commit

• Update forge-std to use newer FS cheatcodes

git rm -rf lib/forge-std

 rm -rf lib/forge-std

 forge install foundry-rs/[email protected] --no-commit

Usage - Getting the most recent deployment

1. Update your foundry.toml to have read permissions on the broadcast folder.

fs_permissions = [
    { access = "read", path = "./broadcast" },
    { access = "read", path = "./reports" },
]

2. Import the package, and call DevOpsTools.get_most_recent_deployment("MyContract", chainid);

ie:

import {DevOpsTools} from "lib/foundry-devops/src/DevOpsTools.sol";
import {MyContract} from "my-contract/MyContract.sol";
.
.
.
function interactWithPreviouslyDeployedContracts() public {
    address contractAddress = DevOpsTools.get_most_recent_deployment("MyContract", block.chainid);
    MyContract myContract = MyContract(contractAddress);
    myContract.doSomething();
}

Usage - zkSync Checker

Prerequisites

• foundry-zksync
  • You'll know you did it right if you can run foundryup-zksync --help and you see a response like:

The installer for Foundry-zksync.

Update or revert to a specific Foundry-zksync version with ease.

Usage - ZkSyncChainChecker

In your contract, you can import and inherit the abstract contract ZkSyncChainChecker to check if you are on a zkSync based chain. And add the skipZkSync modifier to any function you want to skip if you are on a zkSync based chain.

It will check both the precompiles or the chainid to determine if you are on a zkSync based chain.

import {ZkSyncChainChecker} from "lib/foundry-devops/src/ZkSyncChainChecker.sol";

contract MyContract is ZkSyncChainChecker {

  function doStuff() skipZkSync {

ZkSyncChainChecker modifiers:

• skipZkSync: Skips the function if you are on a zkSync based chain.
• onlyZkSync: Only allows the function if you are on a zkSync based chain.

ZkSyncChainChecker Functions:

• isZkSyncChain(): Returns true if you are on a zkSync based chain.
• isOnZkSyncPrecompiles(): Returns true if you are on a zkSync based chain using the precompiles.
• isOnZkSyncChainId(): Returns true if you are on a zkSync based chain using the chainid.

Usage - FoundryZkSyncChecker

In your contract, you can import and inherit the abstract contract FoundryZkSyncChecker to check if you are on the foundry-zksync fork of foundry.

!Important: Functions and modifiers in FoundryZkSyncChecker are only available if you run foundry-zksync with the --zksync flag.

import {FoundryZkSyncChecker} from "lib/foundry-devops/src/FoundryZkSyncChecker.sol";

contract MyContract is FoundryZkSyncChecker {

  function doStuff() onlyFoundryZkSync {

You must also add ffi = true to your foundry.toml to use this feature.

FoundryZkSync modifiers:

• onlyFoundryZkSync: Only allows the function if you are on foundry-zksync
• onlyVanillaFoundry: Only allows the function if you are on foundry

FoundryZkSync Functions:

• is_foundry_zksync: Returns true if you are on foundry-zksync

Testing

For testing on vanilla foundry, run:

make test

For testing with foundry-zksync, run:

make test-zksync

Limitations

• You cannot deploy a contract with FoundryZkSyncChainChecker or ZkSyncChainChecker because foundry-zksync gets confused by a lot of cheatcodes, and doesn't recognize cheatcodes after compiling to the EraVM.
