DeFi Security App combines a standards-based two-factor authentication app with a read-only monitor for the blockchain addresses you care about. TWO-FACTOR AUTHENTICATION Generate time-based one-time passwords (TOTP, RFC 6238) that work with any service supporting 2FA. - Add accounts by scanning a QR code or entering a setup key manually - Rotating 6-digit codes generated locally on your device - Works offline — no connection needed to produce a code - 2FA secrets are stored encrypted on your device and never sent to our servers WALLET & ADDRESS ACTIVITY MONITORING Subscribe to any public blockchain address and follow its on-chain activity. - Build a personal watchlist of addresses - View transactions, token transfers and DeFi interactions - Push notifications when a subscribed address is active - Your watchlist syncs across your devices Activity data is aggregated from established on-chain analytics platforms and block explorers through their public APIs. Only public blockchain data is retrieved. NON-CUSTODIAL AND READ-ONLY DeFi Security App is not a wallet and not an exchange. - It never stores private keys or seed phrases - It never holds or moves funds - It cannot sign, send, swap or trade anything - It does not provide investment or financial advice The app displays public on-chain information and generates local 2FA codes. Nothing more. GETTING STARTED The authenticator works right away — no account, no sign-in, no setup. Just add your 2FA accounts and start generating codes. The monitoring feature uses a free account, which keeps your selected addresses and notification settings synced across your devices. SUPPORT iOS: ios@defisecurity.app
