Overview

CryptoForgeRouter is a production-ready multi-DEX swap router that monetizes trade routing via a configurable protocol fee (0.05%-1%) sent to a fee recipient address. Built on OpenZeppelin v5 with defense-in-depth security patterns.

Key Features

• Multi-DEX routing -- Adapter pattern supports Uniswap V2/V3, SushiSwap, Curve, Balancer, and any custom DEX
• Fee-recipient monetization -- Configurable protocol fee (5-100 bps) collected on every swap
• Multi-hop swaps -- Route through intermediate tokens (A -> B -> C) with mixed adapters per hop
• Permit2 support -- Gasless token approvals via Uniswap's Permit2 signatures
• 24-hour timelock -- Fee rate changes are delayed, giving users predictability
• Emergency controls -- Pause all swaps + sweep stuck tokens
• Ownable2Step -- Two-step ownership transfer prevents accidental loss of admin control
• ReentrancyGuard + CEI -- All swap functions are reentrant-safe
• Deadline enforcement -- All swaps revert if deadline has passed
