Submit Snipe Transactions

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

This endpoint receives a pair of transactions and sends one to the Jito engine and the second to swQoS or white-listed leaders (the same set used for fastBestEffort)

• Call this endpoint with an array of two transactions

• In case you don’t want two snipping transactions to be landed successfully at once, you are responsible for reverting one of these transactions when the other lands first.

• The first transaction will be sent to Jito and has the same requirements as described above. Since it will be sent just to Jito, there is no need for a Priority Fee. Both Jito and bloXroute tips are required

• The second transaction will be sent to bloXroute routing infra either using swQOS or fastBestEffort. A priority fee and bloXroute tip are required. The useStakedRPCs parameter is optional and can be used when submitting the 2nd transaction. If not provided or if False, fastBestEffort is used.
