PolygonETH Calldata Decoder makes debugging smart contracts faster by turning transaction calldata into a clear, human-readable form.
It decodes calldata by automatically fetching the contract's ABI or, if needed, by guessing the invoked function, even when the contract isn't verified.
By presenting the function name, inputs, and their interpreted values, it helps you quickly understand how a transaction interacts with a contract, diagnose issues, and verify expected behavior across supported networks such as Ethereum, Arbitrum, Polygon, Avalanche, BNB Chain, and OP Mainnet.
