AirdropGuard

AirdropGuard is a browser-based wallet safety companion that simulates what a transaction or signature will actually do before you approve it. Users paste a dApp URL or open it through the extension, and AirdropGuard runs a preflight check: contract reputation, bytecode similarity to known drainers, suspicious approval patterns (infinite allowances, delegatecalls), and expected token movements. It then shows a plain-English risk summary and a “what changes in your wallet” diff (allowances, NFTs, tokens). This is not a magic shield—new scams will slip through—but it meaningfully reduces the most common losses caused by blind signing and malicious approvals. The MVP focuses on EVM chains (Ethereum, Base, Arbitrum, Polygon) and supports MetaMask-compatible wallets via standard provider injection. Monetization is freemium: free basic risk checks, paid “pro” for continuous allowance monitoring, alerts, and team features for DAOs.
