Strengths
- Spend directly from the self-custody on-chain Sui balance without selling assets first.
- Visa network with stated acceptance in 150+ countries and 130M+ merchants; virtual and physical card.
- Backed by Mysten Labs (the Sui team) with issuance via RedotPay.
- Self-custody: funds stay in your wallet — the platform cannot touch them.
Weaknesses
- Not yet live: waitlist only, initially for the US.
- Fees (issuance, annual, FX, cashback) not yet announced or published.
- Requires full KYC, so no anonymous use.
- Full KYC required: verified identity, zero pseudonymity.
Verdict
Protection cannot be conclusively assessed: the product is not yet live and its terms (fees, conditions, insurance coverage) are unpublished. The card is self-custody (the balance stays on-chain on Sui under user control), issued through RedotPay's programme on the Visa network. RedotPay operates under a Hong Kong licence and is registered in the US as a Money Services Business (MSB) with FinCEN. Full KYC required.
Medium sovereignty profile for a card: the balance is self-custody on-chain on Sui (the user keeps the keys and need not hand funds to a custodian before spending), a real advantage over custodial cards. However mandatory full KYC and reliance on the RedotPay/Visa issuer for settlement reduce anonymity and introduce censorship/blocking points.

Exact count from JSON-LD structured data (ratingValue 3.784 — ratingCount 2,804), which may differ from the visible label. Again, this is the wallet app, not the card.

Exact figure from Apple's primary endpoint (id 6476572140, US storefront). It covers the Slush wallet app — developer Mysten Labs Inc., bundle com.mystenlabs.suiwallet — not the Slush Card, which as of 9 Aug 2026 has not launched and has no reviews of its own.
Weighted average across 2 public review platforms (2,946 reviews in total), weighted by volume. This is not our rating: it is those platforms’ average.
