Ethereum ABI Retrieval & Verification
Retrieves Ethereum smart contract ABIs and verifies contract metadata across Sourcify, Etherscan, and 4Byte Directory for .NET developers.
This skill enables developers to programmatically fetch Application Binary Interfaces (ABIs) and verify smart contracts using Nethereum's composite lookup pattern. It provides a robust fallback mechanism that chains multiple data sources—Sourcify, Etherscan, and the 4Byte Directory—ensuring high availability of contract metadata even if one service is unavailable. It is particularly useful for building block explorers, wallet integrations, or any C# application requiring dynamic contract interaction, decoding calldata, or resolving proxy implementation addresses.
Características Principales

03Automated proxy contract resolution to fetch underlying implementation ABIs
04Function, event, and error signature lookup by selector or topic hash
05Batch retrieval of multiple ABIs and signatures in a single request
