In RPC mode, you submit a fully user-signed transaction to a dedicated nexroute endpoint. nexroute acknowledges synchronously and routes the transaction through private partnerships for fast, private inclusion. Where on-chain opportunities exist, a backrun is appended atomically behind the user’s transaction. This is one of two integration modes for Capture. Pick RPC mode when you already produce a fully signed user transaction and want privacy, delivery, and backrun in one move. For an alternative where the backrun lands inside the user’s own transaction, see Embedded mode.

​
What you get

  • Private execution: submitted transactions never enter the public mempool
  • Guaranteed delivery: every acknowledged transaction is forwarded. Internal failures fall back to direct routing, never a silent drop
  • Backrun monetization: where on-chain opportunities exist, nexroute appends a backrun behind the user’s transaction; otherwise the transaction is delivered alone
  • Low-latency routing: super-fast inclusion through private partnerships

​
How it works

  1. You sign a user transaction in your normal flow
  2. You POST it to your dedicated Capture endpoint as a JSON-RPC request: eth_sendPrivateRawTransaction for a single transaction, or eth_sendBundle to atomically pack a swap with its ERC-20 approval
  3. nexroute responds immediately with the transaction hash
  4. nexroute evaluates the transaction for backrun opportunity and forwards through private partnerships
  5. The transaction lands on-chain; if a backrun was found, it lands atomically behind it

Reporting

A per-transaction explorer and aggregated reporting dashboard for inclusion status and partner activity is in active development. Contact nexroute for the current status.
