New @KASTcard update lets you deposit & swap SOL, ETH or BTC directly to USDC to spend IRL
good to see the effort to reduce friction here!
MalikonchainMy bank in Dubai called today just to check if I was okay because I haven’t used any of my cards in 3 months. I didn’t know what to say so I just said yeah but honestly it’s just because I’ve been using @KASTcard nonstop since I got it.
KΞVFinally completed 20 transactions with my Virtual Solana @KASTcard 👀
Beyond bullish on purchasing everyday items with stablecoins 🔥
KristelCan say after the last 6 weeks of using Kast in: Toronto, Panama, Asunción, Fog de Iguazú, and Argentina, it's officially replacing my regular CC.
It was battled tested and survived.
LalocriptoCongrats to the @KASTcard team.
Im always looking at projects that are solving real problems and I’ve been able to use the virtual card to pay without any issues
Crypto to payment, no fiat needed.
LockJust used my stablecoins with the KAST card from @KASTcard in Argentina 🇦🇷
No banks. No swaps. Just tap & go.
This is the future of payments.
Abbas KhanNothing is more satisfying than good customer support.
