- CrossChainRouter with BFS path discovery across chain graph - 4 bridge venues: Warp (AWM), Teleport, CCTP, LuxBridge - Triangular + cross-chain arbitrage scanner - HTTP handlers: cross-chain quote, bridges list, arb scan - Gateway: venue router, order management, LP, multihop, Uniswap compat - V4 LXRouter calldata builder with encode/decode - All test tokens use generic LUSD (no white-label refs) - 72 trading tests + gateway tests passing
