KAST
The most complete stablecoin-spending account on the market: US/EU virtual bank accounts from anywhere, Visa Platinum cards with real 1.5% USD cashback on the free tier, instant cashback and no spending caps. Full KYC and a young operator are the trade-offs; the paid tiers only make sense for heavy spenders.
Nuri
The old Nuri bank is dead (2022 insolvency, customers moved to Vivid) - but the brand relaunched at nuri.com as an Estonian self-custody wallet with a free Visa card, IBAN and 130-country reach. Verify listing: card issuance, fees and the provider stack behind the banking rails are unverified; no community track record exists yet.
