eth_sendRawTransaction - Somnia

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 pre-signed transaction to the Somnia network for execution. This is the primary method for broadcasting transactions. With Somnia's sub-second finality and sub-cent fees, transactions are confirmed rapidly and economically.
