My 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.

Finally completed 20 transactions with my Virtual Solana @KASTcard 👀
Beyond bullish on purchasing everyday items with stablecoins 🔥

Can 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.

Congrats 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.

Just used my stablecoins with the KAST card from @KASTcard in Argentina 🇦🇷
No banks. No swaps. Just tap & go.
This is the future of payments.

@KASTcard super underrated still
one of the most useful crypto products imo—you send it stables and then can spend wherever, no need to offramp and it's instant
