Stealf Card
Stealf · ND
Stealf is a self-custody crypto payment card in beta, built on Solana's settlement layer. The model is non-custodial ('you hold the keys') with a strong privacy focus: it uses encrypted MPC compute via Arcium and private transfers via Umbra, with no on-chain link between accounts. As of 2026-06-22 the product is a virtual card distributed in beta (iOS TestFlight, Android Google Play, APK), with an official launch announced for Q1 2026 and stated availability in the USA, UK, EU and 'global'. WARNING: the card's economic parameters are undocumented. Network (Visa/Mastercard), issuance fee, annual fee, FX markup, cashback, ATM fee and limits are all listed as 'TBA' by the sources; in this entry those numeric fields are set to 0 because they are undocumented, not because they are genuinely free. The KYC level and the issuing entity are also not publicly disclosed.

- Solana settlement with stated multi-region availability (USA, UK, EU)
- Self-custody: funds stay in your wallet — the platform cannot touch them.

Verdict
Weak and unverifiable consumer protection. Stealf claims 'fully regulated' infrastructure but does not publicly disclose licenses, issuer or card network, and as of 2026-06-22 it is still in beta. With no verifiable licensing and all economic parameters 'TBA', it offers the consumer no documented guarantees.
Strong on sovereignty. The model is self-custody (the user holds the keys) with privacy by design: MPC compute via Arcium and private transfers via Umbra, with no on-chain link between accounts. This is the product's strongest aspect, though still in beta.
