Wavecard
Wave Space Exploration UAB · Visa
Wavecard (wavecard®) is the Visa debit card from Wave Space Exploration UAB, a Lithuanian company with offices in Berlin and Vilnius, launched in February 2025 as Europe's first self-custodial bitcoin card. It keeps bitcoin in the user's own Lightning wallet until the last possible moment, converting at the point of sale; it supports on-chain and Lightning via Nostr Wallet Connect (NWC). It is available only to EEA residents aged 18+. The virtual card has a one-time 2.99 EUR opening fee (29.99 EUR for the physical card) and no annual fee. The provider charges a 1% conversion fee plus a roughly 0.5% liquidity spread baked into the BTC price. The provider states a 0% FX markup between fiat currencies, but the actual overall currency cost — conversion fee plus spread — is closer to an estimated 1.5%, to be verified case by case. There is no standard cashback (only temporary referral promotions).
Worth it if you pay in bitcoin from a Lightning wallet that stays yours and want a card with no annual fee.
Avoid it if you withdraw cash (3% plus €2) or want cashback: there is none beyond temporary referral promos.

Verdict
Card issued via EEA e-money/VASP infrastructure under a Lithuanian licence (Bank of Lithuania); full KYC. Self-custodial model: bitcoin funds stay in the user's own Lightning wallet and are not held by the issuer, reducing counterparty risk on the crypto balance but shifting custody responsibility onto the user.
Among the most sovereign cards on the market: bitcoin stays in the user's own Lightning wallet via Nostr Wallet Connect and is converted only at the point of sale, without entrusting the crypto balance to a third-party custodian. Full mandatory KYC and reliance on the Visa network remain.
