Solid CardSolid Card
VisaVirtual onlyBorrow Mode: instead of spending your balance down, the card can draw against your savings as collateral, so the USDC you deposited stays in the vault as yield-bearing soUSD and keeps compounding while you pay for coffee with it. Combined with a genuine 0% top-up and 0% transaction fee, the only thing standing between you and free spending is 1% FX outside the dollar.
53 of the 174 priced cards cost less. Among the 113 that ask for exactly as much identity, the median is $1.25.
Whether to take Solid Card
In its favour
- Card issuance is free, top-up is 0%, maintenance is none and standard transactions carry no fee — the only charge is 1% FX on non-USD purchases
- Solid absorbs the cross-border and international transaction fees itself; FX and cross-border are mutually exclusive and capped at 1% combined
- 3% cashback in USDC on every purchase at the base Core tier, rising to 4% at Prime and 5% at Ultra
- Your funds stay in a non-custodial Safe wallet until a transaction actually settles
Against it
- The card cannot be issued to residents of Turkey, Russia, Ukraine, China, India, Israel, Vietnam, Belarus, Cuba, Iran, Iraq, Myanmar, Nepal, Nicaragua, North Korea, Syria or Venezuela
- Even a validly issued card stops working while you are physically located in Cuba, Iran, North Korea, Russia, Syria, Ukraine or Venezuela
- Virtual only — there is no physical card, so anything requiring a plastic card is out
- No ATM access at all, and no ATM fee is published because cash withdrawal is not a feature
Also true, in its favour
- Borrow Mode lets you spend against your savings so the balance keeps earning yield while you pay
- Deposited USDC becomes soUSD, a yield-bearing token that compounds automatically with no staking or lock-up
- The card is issued on the Visa Platinum tier: purchase protection to $10,000, extended warranty to $10,000, price protection to $2,000 and global auto rental insurance
- Sign-up uses passkeys, and the whole flow to an activated card takes most people under three minutes
- Apple Pay and Google Pay work with one tap from the card screen
- Cashback lands directly in Savings as soUSD, so it starts earning the moment it arrives
- Gas and bridging are abstracted away — transfers between users are gasless
- Solid Savings is available worldwide even where the card is not, so you can use the yield side from anywhere

This is one of the genuinely cheap cards: issuance is free, top-up is 0%, there is no maintenance fee, and standard transactions carry no fee. The single charge is a 1% FX fee on any purchase settled in a currency other than USD — built into the exchange rate rather than shown as a line item — and Solid absorbs the cross-border and international transaction fees itself, with FX and cross-border mutually exclusive and capped at 1% combined. Spending limits are not a published number: they are set per user against your available balance or collateral and adjusted dynamically, with Visa verification kicking in above roughly $250,000 and a ceiling near $750,000 on a single transaction. Cashback pays 3% in USDC on the Core tier (up to $50/month), 4% on Prime (up to $100) and 5% on Ultra (up to $200), credited 14 days after settlement. There is no ATM access and therefore no ATM fee. Note for Turkey and Russia in particular: residents of both cannot be issued this card at all.
KYC: what Solid Card asks for
Full verification: a document, a photograph of your face and proof of your address. The same file a bank opens on you, held by a company that is not a bank.
Limits on spending
Not published by the issuer: monthly spend, daily spend, maximum balance, cash, per day.
Confirmed on solid.xyz on July 31, 2026. A figure told to one person in a chat window is not a published limit, so it does not appear here.
Where it works

- Nepal

The other flaws
- Spending limits are not fixed and published; Solid configures them per user and per card and can adjust them at any time
- Cashback is capped by tier at $50, $100 or $200 per month, so the 3–5% headline stops mattering above roughly $1,700–$4,000 of monthly spend
- Cashback is only credited 14 days after the transaction settles
- Full KYC with an ID document and a live selfie is required before the card is issued
- Yield comes from DeFi strategies in BoringVaults — real smart-contract and strategy risk, not a deposit guarantee
- The terms are governed by the laws of Panama, which is a thin venue if you ever need to enforce anything
- US availability is limited to 30-odd states rather than the whole country
- Merchant categories including gambling, high-risk merchants and unregulated financial services are blocked outright
