A web app for guessing ABIs from an address via 4-byte JUMPI instructions.
Created by Google and Infura alumni Andrey Petrov, WhatsABI figures out the ABI of a Solidity smart contract, regardless of it being unregistered. Developers can query events, interfaces, selectors, and database loaders from just the Ethereum smart contract address.
Library of strict TypeScript types applicable to ABIs & EIP712 typed data.
Decodes events and data params from Ethereum transactions.
Parses smart contracts and generates table definitions and queries for ETL.
UI to easily decode Ethereum calldata with contract address, custom ABI or no ABI.
Ethereum ABI tools for Python, in particular, encoding and decoding.
DeFi protocol analyzer for Ethereum ABIs, addresses, and Solidity interfaces.
