eth_getTransactionByHash on X Layer

Supported on SwiftNodes

Everything below was measured on 2026-10-13 by calling eth_getTransactionByHash on X Layer through the same endpoint customers use, and is re-measured weekly.

What eth_getTransactionByHash does

Returns a transaction by its hash: sender, recipient, value, input data, gas fields and signature, plus the block it was included in. It returns null for a hash the node does not know, and a transaction still in the mempool has a null blockNumber.

Transaction types on X Layer

Types of the 62 transactions in five consecutive blocks when we measured. Decoders that reject unknown types will fail on X Layer if any of these is missing from their list.

0x2 EIP-155953 (85%)
0x7e L1-to-L2 deposit (OP Stack)5 (8%)
0x0 legacy4 (6%)

Fields beyond Ethereum's

Type 0x7e (L1-to-L2 deposit (OP Stack)) transactions carry extra fields. depositReceiptVersion: the version of the deposit receipt format; mint: the amount of ETH minted on L2 by a deposit; sourceHash: the unique ID of an L1-to-L2 deposit, derived from its L1 origin.

A real X Layer transaction

A type 0x2 transaction from one of the latest blocks, as our endpoint returned it (long hex values shortened).

Frequently asked questions

Does X Layer support eth_getTransactionByHash?

Yes. eth_getTransactionByHash answered on the SwiftNodes X Layer endpoint when our weekly probe called it through the customer path (2026-10-13).

Which transaction types does X Layer use?

In five recent blocks: 5 × 0x7e (L1-to-L2 deposit (OP Stack)), 53 × 0x2 (EIP-1559), 4 × 0x0 (legacy).

Why does eth_getTransactionByHash return null on X Layer?

The node does not know the hash: it was never broadcast, it was dropped from the mempool, or it was sent to another chain. Check the hash and the chain ID before retrying.

X Layer endpoints, live block height and WebSocket status are on the X Layer RPC page.

One key covers every chain we serve, and SwiftNodes has a free tier.
