ARCHITECTURE
Core Components of Our MEV-Protected Messaging
Our system is engineered from the ground up to secure cross-chain value transfers against front-running, sandwich attacks, and other MEV exploits. Each component is designed for enterprise-grade reliability and seamless integration.
01
Decentralized Relayer Network
A globally distributed network of permissioned relayers ensures message delivery without a single point of failure. Messages are signed and forwarded with cryptographic proofs, guaranteeing censorship resistance and high availability for your dApp's cross-chain operations.
99.9%
Uptime SLA
< 2 sec
Relay Latency
02
Threshold Signature Scheme (TSS)
We implement a multi-party computation (MPC) based TSS for signing cross-chain messages. Private keys are never assembled in one location, eliminating the risk of a single relayer compromise and providing institutional-grade security for transaction authorization.

Single Point of Failure
NIST-Compliant
Cryptography
03
Intent-Based Order Flow
User transactions are expressed as signed intents, not raw transactions. Our system matches and fulfills these intents off-chain via a secure solver network, preventing public mempool exposure and the MEV attacks that target it.

Universal Message Format
A standardized, protocol-agnostic message envelope that works across EVM, Solana, Cosmos, and other major chains. This simplifies integration, reduces development time, and ensures consistent security and verification logic for all supported networks.
