Important to note, that it works only for swaps on and from Ethereum, BNB Smart Chain & Polygon.

This is how it works:

1. Private Transaction Submission:

  • Users submit private transactions on Rubic.

2. bloXroute Processing in BDN:

  • bloXroute, within its Blockchain Distribution Network (BDN), processes private transactions.

3. Direct Routing:

  • Private transactions are routed directly to specific destinations:

  • Ethereum: Sent to the partner block builder.

  • BSC: Sent to bloXroute’s block builder.

  • Polygon: A just-in-time delivery mechanism is used to reduce the chance of frontrunning.

4. Avoiding Public Mempool (For Ethereum and BNB Chain):

  • Private transactions are not propagated to the public mempool.

  • This mitigates the risk of frontrunning and sandwich attacks.

In essence, bloXroute processes private transactions, routes them to designated destinations, labels them as private, and ensures they are not exposed to the public mempool, enhancing security against frontrunning and sandwich attacks.
