説明

ShieldSwap is a privacy-preserving DEX built on Mantle Network. It enables users to swap tokens without exposing their wallet address on-chain, solving the critical privacy gap in DeFi.

Using zero-knowledge proofs (Noir + UltraHonk), users deposit tokens into a shielded pool, swap privately via Merchant Moe DEX integration, and withdraw to any address breaking the on-chain link between their identity and trading activity.

Key innovation: Our relayer-based meta-transaction system lets users sign EIP-712 messages instead of transactions, ensuring their wallet address never appears on-chain during swaps.

ShieldSwap also implements the Privacy Pools compliance model, allowing users to prove their funds come from clean sources without

revealing their identity — privacy with compliance.

ハッカソンの進行状況

- Built 5 ZK circuits in Noir (deposit, withdraw, transfer, swap, compliance) - Deployed smart contracts to Mantle Mainnet (ShieldedPool, RelayAdapt, ASPRegistry) - Integrated Merchant Moe Liquidity Book for atomic shielded swaps - Implemented relayer service for meta-transactions (gasless, private swaps) - Built SDK with browser-based proof generation using bb.js Web Workers - Created Next.js frontend with full deposit/swap/withdraw flows - Deployed frontend to Vercel, relayer to Railway - End-to-end tested on mainnet with real tokens
