# submitBatch

> Non-atomic batch submission of multiple signed transactions. Each transaction is processed independently, and failure of one does not affect others.

<Note>
  **Non-atomicity:** Each transaction in the batch is confirmed and executed independently. If one transaction fails, it does not affect the processing of other transactions in the batch.
</Note>

<Note>
  Append `?anti_mev=1` to the endpoint to enable sandwich-attack protection. See [Anti-MEV](/en/solana/overview/anti_mev) for details.
