Syntax

public static class OpcodesDataExtensions

Methods

GetContractOpcodesByTransactionHashAsync(MirrorRestClient, EvmHash, params IMirrorProjection[])

Retrieves the opcode-level execution trace of a historical transaction, identified by its EVM transaction hash. The mirror node re-executes the transaction on the EVM to produce the trace — for busy transactions this can take several seconds, especially when memory or stack projections are requested.

Declaration

public static Task<OpcodesData?> GetContractOpcodesByTransactionHashAsync(this MirrorRestClient client, EvmHash evmTransactionHash, params IMirrorProjection[] filters)

Parameters

Type	Name	Description
MirrorRestClient	client	Mirror Rest Client to use for the request.
EvmHash	evmTransactionHash	The EVM transaction hash (not to be confused with the raw HAPI transaction hash).
IMirrorProjection[]	filters	Optional projection toggles recognized by this endpoint — OpcodeStackProjectionFilter, OpcodeMemoryProjectionFilter, and OpcodeStorageProjectionFilter. Server defaults are include-stack and exclude-memory / exclude-storage.

Returns

Type	Description
Task<OpcodesData>	The opcode trace, or null if the transaction was not found.

GetContractOpcodesByTransactionIdAsync(MirrorRestClient, TransactionId, params IMirrorProjection[])

Retrieves the opcode-level execution trace of a historical transaction, identified by its HAPI transaction id. The mirror node re-executes the transaction on the EVM to produce the trace — for busy transactions this can take several seconds, especially when memory or stack projections are requested.

Declaration

public static Task<OpcodesData?> GetContractOpcodesByTransactionIdAsync(this MirrorRestClient client, TransactionId transactionId, params IMirrorProjection[] filters)

Parameters

Type	Name	Description
MirrorRestClient	client	Mirror Rest Client to use for the request.
TransactionId	transactionId	The HAPI transaction id, not the EVM transaction hash.
IMirrorProjection[]	filters	Optional projection toggles recognized by this endpoint — OpcodeStackProjectionFilter, OpcodeMemoryProjectionFilter, and OpcodeStorageProjectionFilter. Server defaults are include-stack and exclude-memory / exclude-storage.

Returns

Type	Description
Task<OpcodesData>	The opcode trace, or null if the transaction was not found.
