Submit Signed Transaction

This endpoint is used to submit signed singular transaction.

Transactions submitted to this endpoint must include a bloXroute memo instruction in order to be processed. If you are using the Trader API endpoints or SDKs the instruction will be added automatically. If you want to construct your own transaction and use our submit endpoint, please read more about Transaction Submission. Elite & Ultra tier customers will be exempted if the transaction submitted includes a tipping instruction, to save an instruction in the transaction.
