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.
| メソッド呼び出し | HTTP! | WS! |
|---|---|---|
| trace_block 指定されたブロックで作成されたトレースを返します | ||
| trace_call コールを実行し、実行中に作成されたトレースを返します | ||
| trace_replayBlockTransactions ブロック内のすべてのトランザクションをリプレイし、そのトレースを返します | ||
| trace_replayTransaction トランザクションをリプレイし、そのトレースを返します | ||
| trace_transaction 指定されたトランザクションのすべてのトレースを返します | ||
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.
