# eth\_sendRawTransaction - Tempo

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.

{% hint style="warning" %}
**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.
{% endhint %}
