Overview

@cryptoforge/routing-engine is a high-performance, off-chain routing engine that finds the optimal trade path across multiple DEX pools. It uses graph algorithms (Dijkstra, split-route optimization) to compute the best route for any token pair, accounting for fees, price impact, liquidity depth, and gas costs.

Key Features

• Multi-DEX support — Uniswap V2, Uniswap V3, SushiSwap, Curve, Balancer
• Split-route optimization — Automatically splits large trades across multiple paths to minimize price impact
• Graph-based pathfinding — Dijkstra shortest-path with liquidity-aware edge weights
• Constant product simulation — Full swap simulation with fee deduction and price impact calculation
• Gas-aware quoting — Estimates gas per route and factors it into net output
• Batched RPC calls — Multicall3 for efficient pool data fetching
• Python bindings — Use from Python via subprocess or HTTP API
• Configurable — Max hops, max splits, slippage tolerance, protocol filters, pool exclusions
