DEX Integration
Use Fairseq to prove fair ordering in a matching engine.
DEX users are directly harmed by reordering (front-running and sandwiching). Fairseq provides a proof artifact that the matching engine respected an ordering rule.
Where to integrate
- Before matching: capture the arrival order of intents/orders.
- After matching: prove that the processed order matches the arrival-time constraints.
What you can prove
- FIFO processing of orders
- Consistent ordering under defined tie-break rules
