Pay-with-crypto travel

Coming

Flights, stays, trains and cars, paid with what you hold.

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.

Hold on, this looks like a scam

This address matches one you have used, but five characters are different. It may be a look-alike trying to catch your funds.

0x71C…a93f…4e2B

Cancel I understand the risk

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.
