This repository reproduces the panic issue described in foundry-zksync Issue #1082.

When running tests that use ZkSyncChainChecker and attempt to deploy contracts in the setUp() function, foundry-zksync should panic with a "failed finding contract" error during the zkSync deployment path.

1. Clone this repository
2. Install dependencies:

   forge install

1. Run regular tests (should work fine):

   forge test

2. Run zkSync tests (should trigger the panic):

   forge test --zksync

• Regular tests should pass without issues
• zkSync tests should panic during contract deployment in setUp()

• Solidity: ^0.8.24
• Foundry: foundry-zksync

• XiaoLongBaoToken: Simple ERC20 token with mint functionality
• MerkleAirdrop: Merkle proof-based airdrop contract
• MerkleAirdropTest: Test contract that inherits from ZkSyncChainChecker

The problematic code is in test/MerkleAirdropTest.t.sol in the setUp() function:

if (!isZkSyncChain()) {
    DeployMerkleAirdrop deployer = new DeployMerkleAirdrop();
    (airdrop, token) = deployer.deployMerkleAirdrop();
} else {
    // This should cause the panic
    token = new XiaoLongBaoToken();
    airdrop = new MerkleAirdrop(ROOT, IERC20(address(token)));
    token.mint(address(this), AMOUNT_TO_SEND);
    token.transfer(address(airdrop), AMOUNT_TO_SEND);
}
