ABI Ninja provides an intuitive frontend for contracts from the most popular EVM networks, currently supporting:

• Verified contracts: Pulls the ABI from AnyABI or Etherscan API (fallback)
• Unverified contracts: Two different options are available:
  1. Provide the ABI and the contract address.
  2. Decompile using heimdall-rs (PR in progress).
• Proxy contracts: Currently using evm-proxy-detection to detect proxy contracts and provide the implementation address.

It includes some nice features like:

• (mainnet!) ENS resolution on address inputs.
• Shareable URLs.
• Show TX results.
• Friendly UI even for complex data structures

ABI Ninja has previously received grant money from ENS, which has helped us to make a lot of progress. Since last grant:

• Migration to Scaffold-ETH 2
• Add AnyABI as the first source to fetch verified contracts ABI
• Add Base, Scroll, and ZkSync support
• Improve structs UI
• Allow to iframe into any app as Safe app
• Enable proxy contracts
• Add a decompile option for unverified contracts and improve UI (in progress)
