Simple Card
Simple · Mastercard
Simple Card is the Mastercard from the Simple stablecoin wallet app, operated by Simple Europe UAB (Lithuania, self-custody services) and Stored Assets Ltd (Bulgaria, custody services). Although the Simple app is self-custody, the funds backing the card are held by Unlimit (an e-money institution licensed in Cyprus), so the card itself is custodial. It supports top-up with 24 cryptocurrencies (BTC, ETH, USDC, USDT, SOL, XRP and others), includes a EUR account with SEPA IBAN, a virtual card (physical coming soon), Apple Pay and Google Pay. No issuance or annual fee, FX markup up to 2.5%, no cashback. On-chain settlement details are not documented by official sources (reported as 0).

Verdict
Custodial card: funds are held by Unlimit, an e-money institution licensed in Cyprus, while the Simple app is self-custody. Protection depends on the e-money issuer, not the user.
Limited sovereignty: although the Simple app is self-custody, card funds are held in custody by Unlimit and require full KYC, so you are not the sole controller of the keys on card balances.
