eth_sendRawTransaction - GIWA

Example code for the eth_sendRawTransaction JSON-RPC method. Complete guide on how to use eth_sendRawTransaction JSON-RPC in GetBlock Web3 documentation.

This method submits a signed, serialized transaction to the network for inclusion. It is the only write method on a public endpoint: the transaction must be signed client-side before submission.

Parameters

Parameter	Type	Required	Description
signedTransactionData	string	Yes	0x-prefixed RLP-encoded signed transaction

Response

{
    "jsonrpc": "2.0",
    "id": "getblock.io",
    "result": "0x3c8a1f5b2d9e4076c1a8b3d5e7f9021436587a9cbdef012345678abcdef901234"
}

Response Parameters

Parameter	Type	Description
jsonrpc	string	JSON-RPC protocol version ("2.0")
id	string	Request identifier matching the request
result	string	32-byte transaction hash of the submitted transaction

Use Cases

• Value Transfers: Broadcast a signed native ETH transfer

• Contract Calls: Submit signed state-changing contract interactions

• Contract Deployment: Broadcast signed deployment bytecode

• Batch Submission: Push a queue of pre-signed transactions in nonce order

Error Handling

Error Code	Message	Description
-32602	Invalid params	Malformed or non-hex signed transaction data
-32000	Nonce too low	The transaction nonce is below the account's current nonce
-32010	Transaction rejected	The transaction failed mempool validation
3	Execution reverted	The transaction reverts on execution
