Crypto wallet unlocked by your fingerprint. No seed phrase. Swap ETH & tokens.
Your fingerprint is your key. BioVault is a self-custody wallet for ETH and ERC-20 tokens on Base. There is no seed phrase to write down and no password to forget: your wallet key is created inside your phone's secure hardware and every transaction is approved with your fingerprint. WHY BIOVAULT • No seed phrase. Your key is generated in Android's hardware-backed Keystore (StrongBox where available) and never leaves your phone. • Fingerprint for every transaction. Nothing is sent without a strong biometric match; your device PIN cannot approve transfers. • See exactly what you sign. Every operation is decoded on your phone and shown in plain words, the same text you confirm in the fingerprint prompt. • Lose your phone, not your crypto. Choose 3 trusted guardians. If your phone is lost, any 2 of them can move your wallet to a new phone after a 72-hour safety delay, during which you can cancel. Guardians can never move your funds. • Emergency pause. Stop all outgoing transfers instantly if something looks wrong. EVERYTHING IN ONE WALLET • Send and receive ETH, USDC, EURC, WETH, LINK, cbBTC, cbETH, wstETH, DAI and AERO on Base. • Add any other ERC-20 token by its contract address. • Swap ETH, USDC, EURC and LINK through Uniswap, right inside the app. • Live prices, charts and market data for your assets. • A clear activity history of everything your wallet has signed. BUILT ON SAFE AND ERC-4337 BioVault wallets are Safe smart accounts with an ERC-4337 module and Safe's passkey signer. BioVault's own policy contract adds the guardian recovery, the emergency pause and strict rules on what the wallet can do. SELF-CUSTODY BioVault never holds your keys or your funds and cannot move them. Only you can approve transactions. Biometric data never leaves your phone and is never seen by BioVault. FEES Network fees are paid in ETH from your wallet. Swaps include a 5% BioVault fee, taken from the swap output and shown before you approve. Sending and receiving have no BioVault fee. IMPORTANT BioVault is new software. Its smart contracts have not yet been independently audited, so please keep only amounts you can afford to lose. If you lose your phone and have not set up guardians, your wallet cannot be recovered. Questions? Visit https://biovault.infisecurity.com/support
