Manages and decodes Ethereum smart contract custom errors and reverts within .NET applications using the Nethereum library.

The Nethereum Error Handling skill provides developers with the tools and patterns needed to effectively manage Ethereum smart contract failures in C#. It enables the mapping of Solidity custom errors to C# DTOs, decoding of revert reasons from failed transactions, and the use of typed exceptions for robust error handling. This skill is essential for building resilient decentralized applications (dApps) and enterprise blockchain integrations that require precise troubleshooting and user-friendly error reporting when on-chain transactions fail.

Key Features

01Map Solidity custom errors to C# DTOs using attributes
02Retrieve error reasons from mined failed transactions via hash
03Auto-decode errors using code-generated ContractServiceBase
04Catch and decode SmartContractCustomErrorRevertException instances
05Convert raw hex-encoded error data into typed C# objects
