polyswap

This project creates ERC-20 tokens from Polymarket ERC-1155 positions and deploys them to Uniswap. This converts polymarket into a permisionless, funglible and self-custodying protocol.

The implementation includes tools for extracting positions from Gnosis Safe custody to EOA wallets, wrapping them as ERC-20s, and managing liquidity in the V4 hook. The frontend offers a position dashboard and swap interface supporting YES, NO, and POL tokens, tested with the 'Will Google have the best AI model by September 2025?' market."

Smart Contract Development:

• Uniswap V4 Hooks - Started with Saucepoint's constant-sum AMM implementation and fixed a critical bug in the beforeSwap return delta calculation that would have allowed contract draining. Reverted to univ3 due to difficulty with hook permissions on polygon, to be completed later.
• ERC-1155 to ERC-20 Wrapper - Adapted Gnosis's audited wrapper contracts for Polygon deployment, modifying gas optimizations and network-specific parameters
• Development Tools - Foundry for testing and deployment, Remix for rapid prototyping of V4 hook interactions
• AI Assistance - Nora for smart contract architecture and optimization

Frontend & Integration:

• Web Framework - React. TailwindCSS

• Web3 Stack - RainbowKit for wallet connections, Wagmi/Viem for blockchain interactions, MetaMask as primary wallet

• AI Development - Claude Code for GUI components, Web3 connectors, and Gnosis Safe integration scripts

• Deployment - Vercel for automated CI/CD and hosting

Infrastructure & Testing:

• Network - Polygon mainnet for lower transaction costs and faster confirmations
• Test Market - "Will Google have the best AI model by September 2025?" from Polymarket as proof-of-concept

Key Technical Achievements:

• Fixed critical vulnerability in a specific V4 hook's swap delta calculations
• Implemented MEV-resistant constant-sum AMM (X+Y=K) replacing traditional constant-product curves
• Built complete pipeline from Gnosis Safe custody through ERC-20 wrapping to V4 liquidity pools
• Created unified interface for position tracking and swapping YES/NO/POL tokens
