AppChain Transaction Relays
Frequently Asked Questions
Get clear answers on how our dedicated transaction relay networks accelerate your AppChain's performance and reliability.
Public mempools are shared, congested, and vulnerable to MEV attacks. Our dedicated relay network is a private, permissioned infrastructure layer built specifically for your AppChain. It provides direct, prioritized transaction submission to validators, eliminating public mempool exposure. This reduces front-running risk, decreases latency from minutes to sub-seconds, and ensures transaction ordering aligns with your application's logic, not the highest bidder.
