BB84 Wallet

BB84 Wallet is a self-custodial crypto wallet for the BB84 network, a Layer-2 rollup on Ethereum mainnet. FEATURES • Self-custodial: your keys are generated and stored only on your device; we never have access to them. • Bridge: move ETH, USDC and EURC between Ethereum (L1) and the BB84 network (L2). • Privacy: hash-based one-time addresses (OTAs) instead of reused addresses. • Payments: usernames instead of long addresses, QR codes, recurring payments, merchant payments. • Post-quantum design: transactions are authorized with hash commitments instead of ECDSA signatures. IMPORTANT Balances in this app have real monetary value. Crypto transactions are irreversible. Without a backup your funds are permanently lost if you lose your device. Withdrawals back to Ethereum take 7 days for security reasons. BB84 is new technology; only use amounts you can afford to lose.
