01Own
Your keys never
leave your phone.
B28 is non-custodial. We do not hold your crypto, so we cannot touch it, freeze it, or lose it for you. This is not a promise to behave. We simply have no way in.
No B28 vault
There is nowhere on our side that holds your crypto. Nothing to hack, nothing to freeze, nothing for us to lose.
Locked to your device
Your keys sit in your phone's secure hardware, behind your biometrics. Only you can unlock a transaction.
Yours to take
Export your recovery phrase any time and walk away. No permission, no lock-in. Self-custody, in full.
02Spend
Spend what you own.
Anywhere Visa works.
At the till, your crypto converts to the local currency in one tap. Mid-market rate, with the fee shown before you confirm. The card turns your balance from crypto into spendable money, exactly like the real thing.
Card coming soon. The wallet is live today.
03Protect
Meet the Sentinel.
It speaks first.
Most wallets hand you a blank confirm screen and hope for the best. The Sentinel steps in front of you, reading the address, the token and the transaction, and stops you before a scam can take your money. Safety is not a setting here. It is the whole point.
Every address, screened
Before you sign, B28 checks the recipient against known scams, drainers and look-alike "poisoned" addresses.
Honeypots caught
Tokens engineered so you can buy but never sell are flagged before they can trap your money.
It warns first
The Sentinel speaks before you tap confirm, not in an apology email after your money is gone.
The B28 passport
Other banks freeze you
at the border.
B28 stamps your passport.
Most banks treat crossing a border like a crime. A frozen card, an "unusual activity" email, a decline at the worst moment. B28 does the opposite. The first time your money lands in a new country, it stamps your passport. Your keys cross every border with you.
04Nomad
Money that travels
as well as you do.
Made for people who live across borders. Book flights, trains, cars and stays at good rates, paid with the crypto you already hold. And the first time your money lands somewhere new, B28 stamps your passport instead of freezing your card.
Flights
Compare carriers and book with the crypto you hold.
