# eth\_sendRawTransaction - Celo

The `eth_sendRawTransaction` method submits a pre-signed transaction to the Celo network for execution. This is the primary method for broadcasting transactions. With Celo's one-block finality and sub-cent fees, transactions are confirmed rapidly and economically. Celo also supports fee abstraction, allowing gas to be paid in stablecoins.
