Tips for trace methods
Trace Options
You may give trace API function a secondary optional argument, which specifies the options for this specific call. The possible options are:
- disableStorage:
BOOLEAN- Setting this to true will disable storage capture (default = false). - disableMemory:
BOOLEAN- Setting this to true will disable memory capture (default = false). - disableStack:
BOOLEAN- Setting this to true will disable stack capture (default = false). - enableReturnData:
BOOLEAN- Setting this to true will disable stack capture (default = false). - tracer:
STRING- Setting this option enables transaction tracing using Go or JavaScript-based tracers. For more details, please refer to https://geth.ethereum.org/docs/developers/evm-tracing/built-in-tracers. When this option is enabled, all four preceding parameters will be ignored. You can also use pre-defined tracing tools as listed below:
| Tracer Name | Description |
|---|---|
| 4byteTracer | The 4byteTracer collects 4-byte identifiers for post-processing. It collects method identifiers along with the size of the provided data, enabling a reverse lookup of signatures corresponding to the data size. |
| callTracer | The callTracer is a transaction tracing tool equipped with the capability to extract and report all internal calls and other useful information generated within a transaction. |
| fastCallTracer | fallCallTracer is the Go-native version of callTracer. It offers a 10x performance improvement compared to callTracer since it does not execute in the JavaScript VM. If performance is a top priority, please consider using fastCallTracer instead of callTracer. |
| evmdisTracer | The evmdisTracer provides sufficient information to execute the disassembly in evmdis format. |
| noopTracer | The noopTracer is a basic boilerplate code in JavaScript used for transaction tracing within a JavaScript object. |
| opcountTracer | The opcountTracer is a sample tracing tool that counts the number of operations executed by the KLVM (K Framework LLVM) before the transaction is completed. |
| prestateTracer | The prestateTracer outputs sufficient information to generate transaction local execution from a custom-assembled genesis block. |
| revertTracer | The revertTracer outputs the error string of the REVERT opcode. If execution does not revert, it will output an empty string. |
| unigramTracer | The unigramTracer returns the frequency of each opcode occurrence. |
| bigramTracer | The bigramTracer returns the frequency of occurrences of consecutive pairs of opcodes. |
| trigramTracer | The trigramTracer returns the frequency of occurrences of consecutive triplets of opcodes. |
