What the Sana Card is
Sana is a self-custody onchain money app built on Solana, and the Sana Card is a Visa Signature card that turns an onchain balance into everyday spending. The distinguishing feature is the collateral structure: each card has its own onchain collateral address, you deposit USDC or USDT from your Sana wallet, the merchant is paid in fiat at the swipe, and you repay Sana.
Accepted at 150 million-plus Visa merchants, usable online and in stores through Apple Pay or Google Pay, with the virtual card live today and a physical card announced for later. The whole application runs in the app - download Sana, verify identity through Sumsub, activate the card.
The costs, split between marketing and terms
The card page leads with 0% FX markup on USDC, and there is no annual fee and 0% interest on purchases. The binding card terms are more specific, and worth reading together:
- Foreign exchange fee on non-USD transactions: up to 3%
- Cross-border fee: up to 3%
- Late payment: up to $40; returned payment: up to $29
- Interest: currently 0%, with the issuer and Sana reserving the right to introduce it on new purchases with notice
So the 0% claim applies to dollar spending, while anything cross-border can carry up to 3% in each of two separate categories. That is not unusual for a US-issued programme, but it should be the first number you check on your own spending pattern.
The collateral model, which is the real trade-off
This is a secured account: by accepting the terms you grant the issuer a security interest in your collateral, and no part of that collateral may secure other loans. A liquidation event occurs if an outstanding obligation is not paid in full within one calendar day, or if the market value of your collateral drops below the value of your existing charges and you neither add collateral nor pay down the balance. You also agree to pay the gas fees on any liquidation, taken from the collateral.
In practice that means the card is only as safe as your collateral management: hold more than you are spending, do not let an outstanding balance drift, and understand that a stablecoin depeg or a mispriced oracle is a risk you carry rather than the issuer. Sana also states it does not control the smart contracts holding your collateral.
Rewards and the API
Rewards accrue as $SANA per swipe, claimable onchain from the app once you hit the threshold, with no points and no expiry - the reward is denominated in Sana's own token. Separately, Sana exposes an API for issuing cards programmatically, letting developers set per-transaction and per-day limits and stream authorisations through a policy engine, aimed at issuing cards for users or AI agents at scale.
Who it suits
If you hold USDC or USDT on Solana, want a Visa Signature card without selling first, and are comfortable managing collateral actively, this is one of the more transparently documented self-custody programmes - named issuer, published fee disclosures and clear liquidation rules. If you are a US person you cannot apply at all, and if you want the same idea without the collateral mechanics, compare RayCash or browse the crypto cards directory.
