Ethereum RPC
Overview
Theeth_sendRawTransaction RPC method is used to facilitate the transmission of a signed and serialized Ethereum transaction onto the network. This approach proves invaluable when seeking complete oversight of the signing procedure, especially when employing hardware wallets, cold storage solutions, or custom signing libraries. Its versatility shines through in multiple scenarios, including Ether transfers, smart contract interactions, and contract deployments.
Parameters
Transaction data: This is a required parameter. It is a hex string that represents the signed transaction data. This data must be prepared and signed offline or through a wallet before being sent to the network.
Returns
The response from the eth_sendRawTransaction method is a JSON object containing the following fields:
| Name | Description |
|---|---|
| jsonrpc | A string indicating the version of the JSON-RPC protocol. It should be "2.0". |
| id | A number that identifies the request. This should match the id value in the request. |
| result | The transaction hash of the sent transaction. If the transaction is not yet available, this will be the zero hash. |
