Description
Blocks wallet drainers, crypto phishing, clipboard address swaps and seed phrase theft. Passive Web3 protection. Manifest V3. SafeAgent by Holder.io is a passive Web3 security extension that protects you from the four most common crypto attacks — quietly, locally, with zero setup. WHAT IT BLOCKS • Wallet drainers — intercepts dangerous signature requests (approve, setApprovalForAll, permit) and stops unlimited approvals to unknown contracts before they reach MetaMask, Rabby, Coinbase Wallet or any EIP-1193 wallet. • Crypto phishing — blocks known scam domains and typosquatted look-alikes of popular exchanges, wallets and DeFi apps. • Clipboard hijacking — detects when the wallet address you copied is silently replaced by a clipper and restores the original in one click. • Seed phrase theft — warns when a web page asks for your 12/24-word recovery phrase. Legitimate apps never do that on a website. PRIVATE BY DESIGN Everything runs 100% locally in your browser: no accounts, no analytics, no tracking. Your browsing history, clipboard and keys never leave your device. MANIFEST V3 COMPLIANT Built on Chrome's newest, most secure extension platform: strict Content Security Policy, no remote code, no unsafe-eval. MULTI-CHAIN Ethereum, BNB Chain, Polygon, Arbitrum and other EVM networks; recognizes ETH, BTC, TRX and SOL addresses in the clipboard. Free. 12 languages. Made by Holder — support: me@holder.io
