Does it support proxy contracts?

Yes, it includes specific workflows for verifying both the implementation and proxy contracts for patterns like ERC1967 and UUPS.

What are the prerequisites for using this skill?

You need Foundry version 1.3.6 or higher installed, the contract address, the chain ID, an explorer API key, and the matching source code.

How does it handle constructor arguments?

The skill can extract arguments from deployment broadcasts or use 'cast abi-encode' to manually generate the required ABI-encoded data.

What happens if my bytecode doesn't match?

The skill provides troubleshooting steps, such as checking out the specific deployment commit and reinstalling dependencies to eliminate compilation drift.

Can I verify contracts on chains not natively supported by Foundry?

Yes, this skill provides a method to use the Etherscan V2 API via the --verifier-url flag to support a wider range of networks.

Verifies smart contracts on Etherscan-compatible block explorers using Foundry integration.

Acerca de

This skill automates the process of verifying smart contract source code on blockchain explorers, ensuring transparency and trust for decentralized applications. It leverages Foundry’s forge verify-contract command to handle complex scenarios, including the Etherscan V2 API for newer chains, proxy patterns such as ERC1967 and UUPS, and factory-created contracts via CREATE2. By automatically extracting constructor arguments and managing multi-chain configurations, it streamlines the essential final step of the blockchain deployment pipeline within the Claude Code environment.
