Submit Paladin Transaction

This endpoint is used to submit a transaction ONLY to Paladin validators.

As of 01/15/2025,

This endpoint is used to send transactions ONLY via the Paladin Port. At the first stage, it will work only for transactions with a minimal priority fee of 0.1 SOL & a bloXroute tip of 0.1 SOL and above. This allows users to create separate transactions for P3 that focus more on priority fees.

Trader API will do a 20ms priority fee auction and submit the leading transactions to the Paladin validator. Transactions that are not winning the auctions are sent after 50ms. Auction is performed based on priority fee as primary key and transactions with similar priority fee range are sorted by tip transactions with priority fee below 10 Lamports/CU are not sent to Paladin port. This auction applies to Trader API swQoS, fastBestEffort and the new Paladin-only submissions.
