# Submit Batch Transaction

This endpoint is used to submit multiple signed transactions in a single batch. The batch order defines an execution order as well. In case of failure of a single transaction a whole batch is skipped.

{% hint style="info" %}
Transactions submitted to this endpoint must include a bloXroute tip instruction in order to be processed. Here use a tip address provided by `Get Tip Wallet` method.
