ENTERPRISE-GRADE FOUNDATION
Core Architecture of Our Relay Network
Our encrypted mempool relay is built on a purpose-designed architecture that prioritizes security, speed, and reliability for high-value cross-chain transactions.
01
Zero-Knowledge Proof Encryption
Transaction payloads are encrypted using zk-SNARKs before entering the relay, ensuring complete privacy from front-running bots and malicious actors. Only the intended destination chain can decrypt and execute.
256-bit
Encryption
zk-SNARKs
Proof System
02
Decentralized Validator Network
A globally distributed network of independent, permissioned validators operates the relay nodes. This eliminates single points of failure and ensures censorship resistance for transaction propagation.

03
Multi-Chain State Verification
Our relay nodes maintain real-time, cryptographically verified state proofs for connected chains (Ethereum, Solana, Polygon, etc.), guaranteeing the validity of cross-chain intents before commitment.

Frequently Asked Questions
Get clear answers on how our encrypted relay network integrates with your protocol, from deployment to ongoing operations.
Our network operates as a secure, decentralized layer that intercepts pending transactions from public mempools before they are mined. Transactions are encrypted using threshold cryptography, routed through our global relay nodes, and only decrypted and submitted to the destination chain's mempool at the optimal moment for execution. This prevents frontrunning and MEV extraction while ensuring transaction privacy and finality.
