Most crypto wallets ask you to choose between two bad options: hand your keys to a company you have to trust, or hold your keys yourself and have nowhere to spend. B28 refuses that trade. You keep your own keys, and we are building the bridge that turns what you hold into money you can use.
What we are building
B28 is a non-custodial crypto wallet. Your keys are generated and stored on your own device, inside the phone's secure hardware behind your fingerprint or face. We never hold, control, or access your funds. You can export your recovery phrase at any time, and because it lives only with you, if you lose it we cannot recover it for you.
The wallet is live today. You can hold, send, and receive across 16 networks, talk to B28 in plain language, and let the Sentinel scam-shield check a transaction before you sign it. The part that is still coming is the instant-convert Visa card: the piece that lets you spend your crypto anywhere, converted at the moment you tap. We will never describe the card as live until it is.
Safety is the brand
We think the most valuable thing a wallet can do is stop you from losing money. That is why the Sentinel speaks before you confirm a transfer: it screens the recipient address and the token against known scams, drainer approvals, look-alike "address poisoning", and honeypot tokens, and warns you first. The assistant you can talk to prepares actions for you to approve with your fingerprint. It will not give buy or sell advice, it will not hold your keys, and it never moves money on its own.
Honest by design
We would rather tell you what is not finished than dress it up. Holding and receiving are free. Sending is free from us, you pay only the network's own fee. In-app convert carries a small, clearly shown fee. You can read the full breakdown on our fees page, and how self-custody works on self-custody. We collect only what we need, which on this site is the email you give us for early access. See our privacy page for the details.
B28 is not a bank. We do not take deposits, we are not a regulated deposit institution, and crypto is volatile and uninsured. We do not pretend otherwise.
Who operates B28
B28 is operated by B28 OÜ, a company based in Tallinn, Estonia. One company, one team, building one product carefully. If you want to reach us, write to hello@joinb28.app, or for anything security related, security@joinb28.app.
An independent security review of the wallet will be published before the card launches.
