View Source Signet.DebugTrace (Signet v1.3.8)

Represents an Ethereum transaction debug trace, which contains information about the call graph of an executed transaction. Note: this is different from trace_call and instead has deep struct logs for execution.

See Signet.RPC.debug_trace_call for getting traces from an Ethereum JSON-RPC host.

Summary

Types

t()

Functions

deserialize(params)
