🛡️ Safe Approval Guard

Smart token approval management for EOA and Safe Wallets

Problem

• Users approve unlimited spending to unknown contracts
• Safe Wallets (multi-sig) have no easy way to audit/revoke approvals
• Rug pulls exploit unlimited approvals (e.g., $600M Ronin hack)
• No tool unifies EOA + Safe approval management

Solution

A security dashboard that:

1. Scans all ERC20/ERC721 approvals for any wallet
2. Risk scores each approval (trusted/unknown/scam)
3. Batch revokes risky approvals
4. Safe-native — creates multi-sig tx proposals for Safe wallets

Features

Phase 1 (MVP - Current)

• ✅ Connect MetaMask / Safe Wallet
• ✅ Fetch ERC20 token approvals
• ✅ Risk levels: 🟢 Safe / 🟡 Unknown / 🔴 Risky
• ✅ Revoke approval (single)

Phase 2 (Safe Integration)

• Safe Wallet SDK integration
• Create batch revoke as Safe transaction
• Multi-chain support (ETH, Arbitrum, Base, Polygon)
