Tempo API method that sends a signed transaction to the network. Tempo supports standard Ethereum transaction types plus type 0x76 (TempoTransaction) with features like passkey authentication, call batching, and fee sponsorship.
Get your own node endpoint todayStart for free and get your app to production levels immediately. No credit card required.You can sign up with your GitHub, X, Google, or Microsoft account.
Stablecoin gas fees: On Tempo, transaction fees are paid in TIP-20 stablecoins like pathUSD, not a native token. The fee is automatically converted using the Fee AMM.

​
Parameters

  • signedTransaction — the signed transaction data as a hex string

​
Response

  • result — the transaction hash of the submitted transaction
