À propos de l'application

KeyOne — spend crypto like cash.

KeyOne pairs a self-custodial crypto wallet with a payment card you can use anywhere cards are accepted — in shops, online and in your phone wallet.

SELF-CUSTODY
Your keys stay on your device. Nobody, not even KeyOne, can move your funds without you. Every transaction is signed on your phone.

CARD
Top up the card from crypto in seconds and pay wherever you like. Freeze it, reveal details or manage limits right from the app. 3-D Secure confirmations arrive as push notifications.

INSTANT SWAPS
Swap between supported cryptocurrencies and EUR/USD balances at transparent rates, without leaving the app.

SEND TO FRIENDS
Transfer to other KeyOne users instantly and free — just pick a recipient.

ACTIVITY & SPENDING
See every payment, swap and transfer in one feed, with merchant logos, categories and monthly spending breakdowns.

SECURITY
PIN and biometric lock, on-device key storage, identity verification and real-time notifications for every card payment.

Card and EUR/USD accounts are issued and operated by a licensed e-money institution partner. Availability of the card depends on your country of residence; identity verification (KYC) is required for card and fiat services. Cryptocurrency values can fluctuate; KeyOne does not provide investment advice.
