Step 3 — Broadcast the Transaction

Broadcast the transaction payload returned in Step 2 using chain-native signing tooling.

Endpoint guidance

There is no single REST endpoint for standard swap broadcast. Use returned msgs with your chain stack:

• EVM: sign and send transactions with your EVM provider/wallet.
• Cosmos: sign and broadcast messages with Cosmos SDK tooling.

If you use Euclid meta transactions, see:

• Meta Transactions — Sign
• Meta Transactions — Broadcast

Minimal execution flow

• EVM: sign/send each item in msgs (to, data, value).
• Cosmos: broadcast the returned contract messages with your signer.

Required data to persist

• Source-chain transaction hash(es).
• Sender address and source chain UID.
• Execution timestamp for timeout/retry policy.

Next step: Track Execution.
