BB84 Wallet

BB84 Wallet is a self-custodial cryptocurrency wallet. It connects to the BB84 network, a Layer-2 rollup that currently settles to Ethereum Sepolia, a public Ethereum test network. IMPORTANT — NO REAL-WORLD VALUE Because BB84 currently runs on Ethereum Sepolia, all balances, tokens, and transactions in this app are test values with no real-world monetary worth. Nothing you send, receive, or hold in this app can be exchanged for real money. This disclosure is about the network the app connects to, not the app itself — every feature below is fully implemented and functional. FEATURES • Self-custodial — your private keys are generated and stored only on your device; we never have access to them. • Bridge — move ETH between Ethereum Sepolia (L1) and the BB84 network (L2) and back. • Privacy-preserving transactions — BB84 uses hash-based one-time addresses (OTAs) instead of classical public-key cryptography, so recipient addresses aren't reused. • Human-readable usernames — register a name instead of sharing a raw address. BB84 Wallet is a fully functional wallet application, built for anyone who wants to try a hash-based Layer-2 rollup design firsthand.
