Drainer Guard

Blocks crypto drainer sites, malicious wallet approvals, and seed-phrase phishing. Universal detection with live threat feeds.

Drainer Guard blocks crypto-drainer sites before they can steal your wallet. WHAT IT DOES: blocks known drainer domains via live threat feeds (ScamSniffer + MetaMask eth-phishing-detect, refreshed every 12h) plus a bundled seed blocklist enforced at the network layer; detects brand-new drainers with universal heuristics (seed-phrase harvesting inputs, setApprovalForAll / Permit2 / eth_signTypedData markers, obfuscation, airdrop-claim lures); guards wallet calls by blocking malicious signatures and approvals to unknown spenders on flagged pages; allowlists legit DeFi (Uniswap, Aave) for zero false positives. PRIVACY-FIRST: fully offline by default, no account, no analytics, nothing leaves your device.
