eth_getTransactionReceipt

Returns the receipt for a transaction. Flashblocks endpoints can return preconfirmed receipt data from cache before the block seals.

Returns the receipt for a transaction by its hash. On Standard RPC endpoints, receipts are available after a transaction is included in a sealed block. On Flashblocks RPC endpoints, this method can return preconfirmed receipt data from the Flashblocks cache before the block seals.

Preconfirmed receipts are reorg-able until the full L2 block seals. This method does not accept a pending parameter; Flashblocks behavior is selected by using a Flashblocks RPC endpoint. See the RPC Overview for the canonical method matrix.

Parameters

transactionHash · string · required

The 32-byte transaction hash.

Returns

result · object | null

The transaction receipt object, or null if the transaction was not found. On Flashblocks endpoints, the result can be a preconfirmed receipt from the Flashblocks cache.

Flashblock-Specific Response Fields

Before Azul, the Flashblocks infrastructure stream included pre-confirmed receipt data inside the metadata.receipts object of each Flashblock payload before the block sealed. Azul removes receipts from the raw WebSocket payload. Applications should use Flashblocks RPC by-hash lookups or subscriptions instead of depending on raw stream receipt payloads.

Field	Flashblock metadata.receipts[hash]
type	Transaction type (0x0, 0x1, 0x2, 0x7e)
status	"0x1" success / "0x0" failure
cumulativeGasUsed	Cumulative gas in block to this transaction
logs	Emitted log objects
logsBloom	Bloom filter
transactionIndex	Index in block
