TraceFast live Ethereum data
TraceFast live Ethereum data: every call frame a transaction executed, the order it ran — the caller and target of each, the kind of call, the value and gas it moved, its own outcome, and why it reverted where it did. Path hash: Transaction hash, `0x`-prefixed, 64 hex characters, any case. Query: includeCalldata, limit (see docs). Docs: https://docs.tracefast.xyz/api/trace.md
