eth_sendRawTransaction - Tempo

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

Broadcasts a signed transaction. Accepts both standard EVM transaction types (0x0 legacy, 0x1 EIP-2930, 0x2 EIP-1559, 0x7702 EIP-7702) and Tempo Transactions (type 0x54) — a Tempo-specific transaction type used for payment flows with structured memo fields, fee-payer sponsorship, and direct routing to subblock proposers. Transactions targeting a specific subblock proposer are routed to the consensus layer when submitted to the matching validator node; other nodes reject them. The transaction value field is effectively ignored — fees and transfers are TIP-20-denominated, not native-token-denominated.

MODIFIED FROM STANDARD EVM. Tempo has no native gas token — this method's behavior differs from standard Ethereum nodes. See the description below for the Tempo-specific semantics.
