DEX VM (D-Chain)

The DEX VM (D-Chain) is a purpose-built virtual machine for decentralized exchange operations. It provides a Central Limit Order Book (CLOB), Automated Market Maker (AMM) liquidity pools, perpetual futures contracts, and cross-chain atomic swaps via Warp messaging. The VM uses a pure functional architecture where all state transitions happen deterministically within block processing.

Architecture

• CLOB Trading: Full order book with limit and market orders, sub-millisecond matching
• AMM Liquidity Pools: Configurable fee tiers, concentrated liquidity
• Perpetual Futures: Margin accounts, funding rates, liquidation engine, auto-deleveraging (ADL)
• MEV Protection: Commit-reveal scheme prevents front-running
• Cross-Chain Swaps: Atomic swaps via Lux Warp messaging
• 1ms Block Times: Ultra-low latency for HFT workloads
