submit-snipe

This endpoint is designed to maximize your landing speed for a pair of transactions that compete with each other (mainly token sniping use case).

This endpoint accepts a pair of competing transactions and submits the first to the Jito block engine while sending the second through bloXroute staked connections. Both transactions must include a minimum bloXroute tip of 0.001 SOL, and the first transaction must also include a valid tip to one of Jito’s tipping wallets.

Since the first transaction is submitted through Jito-protected flow, a priority fee is generally not required, while the second transaction sent through staked connections should include a competitive priority fee.

If you do not want both sniping transactions to land successfully, you are responsible for making them mutually exclusive, such as by using the same durable nonce so that the first landing transaction invalidates the other.
