Lattice: An Intent-Based DeFi Coordination Layer

Lattice is a cutting-edge, intent-based DeFi coordination layer built on js-libp2p. It enables users to sign their desired transactions, which are then processed by a private mesh of solvers competing to fulfill them. The system prioritizes privacy and efficiency, ensuring that intents are settled on-chain without exposure to the mempool or risk of MEV leaks, and without the need for a trusted relayer.

• Core Functionality: Facilitates private intent propagation through an encrypted solver mesh, with auctions resolving in under 100ms, and only the winning solution being submitted to the blockchain.
• Key Features:
  • Privacy-Preserving Transactions: Intents are encrypted and settled privately, preventing front-running and MEV.
  • Decentralized Coordination: Operates entirely peer-to-peer, moving coordination off-chain and reducing reliance on centralized APIs.
  • High Performance: Achieves sub-100ms transaction settlement through optimized P2P networking and efficient auction mechanisms.
  • Robust Architecture: Utilizes js-libp2p for networking (including Noise encryption, yamux multiplexing, Kademlia DHT, and GossipSub), and the EVM for trust and settlement.
  • Developer Friendly: Built with modern technologies like Node.js (ESM), Solidity, and ethers.js, with comprehensive documentation and troubleshooting guides.
• Technology Stack: Leverages js-libp2p for P2P networking, GossipSub for intent propagation, ethers.js for EVM interactions (EIP-712 signing), and Solidity for smart contracts. The runtime environment is Node.js.
• Roadmap: The project outlines a clear development roadmap covering foundational P2P networking, intent validation, auction engines, EVM settlement, and hardening for launch.

Lattice aims to redefine DeFi coordination by providing a secure, private, and highly efficient solution for transaction settlement.
