TraceFast

TraceFast live Ethereum data: the failed call frames of a reverted transaction — for each, its position in the call tree, caller and target, the kind of failure (revert, panic, custom error, out of gas, …), the revert payload with its selector, and the error name when the selector is known. Path hash: Transaction hash, `0x`-prefixed, 64 hex characters, any case. Docs: https://docs.tracefast.xyz/api/transaction-failures.md
