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

• Verified contracts: Pulls the ABI with getsourcecode endpoint from Etherscan.
• Unverified contracts: Two different options are available:
  1. Provide the ABI and the contract address.
  2. Decompile using heimdall-rs.
• Proxy contracts: Also using getsourcecode endpoint to detect proxy contracts and provide the implementation address.

It includes some nice features like:

• (mainnet!) ENS resolution on address inputs.
• Shareable URLs with cool dynamic unfurl.
• Show TX results.
• Works also on localhost! Useful to test your contracts while developing them.
• Friendly UI even for complex data structures, now with dark mode!
