Class TransactionHashFilter

Predicate filter on the transaction.hash query parameter of the cross-contract logs endpoint (/api/v1/contracts/results/logs). Scopes the returned log events to a single transaction without needing to know which contract emitted them.

Syntax

public sealed class TransactionHashFilter : IMirrorFilter, IMirrorQueryParameter

Remarks

The wire format accepts either a 32-byte Ethereum transaction hash (64 hex chars) or a 48-byte Hedera SHA-384 transaction hash (96 hex chars). Use Is(EvmHash) when you already have an EvmHash; use Is(ReadOnlyMemory<byte>) for raw bytes (EVM 32-byte or Hedera 48-byte). Construct via the static factories; the ctor is private.

Methods

Is(EvmHash)

Records whose transaction.hash equals the given 32-byte EVM transaction hash.

Declaration

public static TransactionHashFilter Is(EvmHash evmHash)

Parameters

Type	Name	Description
EvmHash	evmHash	The EVM transaction hash (32 bytes, keccak-256).

Returns

Type	Description
TransactionHashFilter

Is(ReadOnlyMemory<byte>)

Records whose transaction.hash equals the given raw hash bytes. Accepts 32-byte EVM hashes and 48-byte Hedera SHA-384 hashes; any other length throws.

Declaration

public static TransactionHashFilter Is(ReadOnlyMemory<byte> hash)

Parameters

Type	Name	Description
ReadOnlyMemory<byte>	hash	The transaction hash bytes — must be 32 or 48 bytes.

Returns

Type	Description
TransactionHashFilter

Exceptions

Type	Condition
ArgumentOutOfRangeException	Thrown when hash is neither 32 nor 48 bytes long.
