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 have not yet been announced by the sources, and nothing indicates they are genuinely free. The official site now states banking and card-issuance infrastructure via Rain and wallet security via Turnkey; the KYC level and the legal issuing entity remain undisclosed.

Strengths
- Self-custody model: the user holds the keys to the private wallet
- Privacy by design: MPC via Arcium and private transfers via Umbra, no on-chain link between accounts
- Solana settlement with stated multi-region availability (USA, UK, EU)
- Self-custody: funds stay in your wallet — the platform cannot touch them.
- Light KYC: minimal identity verification.
Weaknesses
- Undocumented economics: network, fees, cashback and limits not yet announced
- Still in beta with undisclosed issuer and licensing
- 'Fully regulated' claim not backed by verifiable public licenses
- No notable sovereignty drawback documented.
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 economic parameters not yet announced, 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.
