Viem Transaction Tracer

Viem-tracer is a utility library designed to enhance debugging of Ethereum transactions when using Viem by providing automatic decoding of transaction traces. It integrates with clients configured for `anvil` or `hardhat` modes, leveraging `debug_traceCall` to display detailed call flows and revert reasons. The library automatically appends formatted traces to error messages for failed `eth_estimateGas` and `eth_sendTransaction` RPC requests. It is currently at version 1.8.0, with frequent minor releases as seen by the November 2025 and May 2025 activity. A key differentiator is its automatic integration with `viem` transports and its ability to decode transaction details using services like openchain.xyz, providing human-readable output for debugging.
