Ethereum Trace Methods
This section documents Ethereum's trace API methods that provide detailed execution traces for transactions and blocks. These methods are instrumental for developers needing in-depth visibility into transaction execution, contract interactions, and state changes.
Trace Methods Overview
Trace methods allow developers to obtain comprehensive execution traces for transactions and blocks, providing visibility into the complete call hierarchy, state changes, and execution flow. These powerful tools enable advanced debugging, analytics, and monitoring capabilities essential for sophisticated Ethereum applications.
| Llamadas a Métodos | HTTP! | WS! |
|---|---|---|
| trace_block Devuelve trazas creadas en un bloque dado | ||
| trace_call Ejecuta una llamada y devuelve las trazas creadas durante la ejecución | ||
| trace_replayBlockTransactions Reproduce todas las transacciones en un bloque y devuelve sus trazas | ||
| trace_replayTransaction Reproduce una transacción y devuelve su traza | ||
| trace_transaction Devuelve todas las trazas de una transacción dada | ||
The trace namespace provides methods for:
- Obtaining detailed traces for individual transactions
- Tracing all transactions within a block
- Replaying transactions with different parameters
- Filtering traces based on specific criteria
- Executing trace calls without modifying state
- Analyzing internal transactions and contract calls
These methods are particularly valuable for:
- Smart contract debugging and validation
- Transaction analysis tools
- Monitoring contract interactions
- Forensic blockchain analysis
- Gas optimization research
Each trace method provides structured output detailing call hierarchies, executed opcodes, gas consumption, and state modifications at each step of execution.
