Who issues your card
The Solid Card is issued by one of our two card program partners, Rain or Wirex, depending on your country of residence. The program is assigned automatically when you order. Limits, merchant rules and terms follow the program that issued your card, so a few details below can vary.
Spending Limits
Your spending limits are:
Based on your available card balance or collateral
Configurable by Solid per user and per card
Dynamically adjustable at any time
Your card spends only its Spendable balance, shown at the top of the card screen. The total balance in the app also counts your Wallet and Savings, which the card does not use until you move that money onto the card.
Limits can be applied across the following intervals:
Per transaction
Daily (per 24-hour period)
Weekly (per 7-day period)
Monthly (per 30-day period)
Yearly
Lifetime
High-value transactions may trigger additional checks:
Transactions above ~$250,000 may require verification from Visa
Maximum single transaction limit: up to ~$750,000
Fees
In short: getting the card is free, adding money is free, and spending in US dollars is free. The only cost is on purchases in a currency other than USD, where two FX fees apply: 1% from your card provider (Rain or Wirex, built into the exchange rate) plus a Solid FX fee of 1% at Core, 0.5% at Prime and 0% at Ultra. That is a total of 2% at Core, 1.5% at Prime and 1% at Ultra. Cashback is higher than that at every tier, so you still come out ahead. Wirex cardholders can also pay euro purchases with no conversion and no FX fee at all, from a EUR balance or from soUSD with Credit mode on; see Spending in euros with zero fees below.
Fee | Core | Prime | Ultra |
Card issuance, monthly fee, top-up | Free | Free | Free |
Spend in USD | Free | Free | Free |
Spend in EUR from your EUR balance or from soUSD with Credit mode (Wirex cards) | Free | Free | Free |
Card provider FX fee (non-USD spend) | 1% | 1% | 1% |
Solid FX fee (non-USD spend) | 1% | 0.5% | Free |
Total FX cost on non-USD spend | 2% | 1.5% | 1% |
Cross-border and international transaction fees | Covered by Solid | Covered by Solid | Covered by Solid |
Cashback on eligible purchases | 3% | 4% | 5% |
Adding money (top-up)
Solid top-up fee: 0%. Solid does not take a cut for loading funds: the full amount that reaches your card is available to spend.
Minimum card deposit: $10. A deposit under $10 sent to your card goes to your Solid Wallet instead and shows as Sent to Safe. Nothing is lost, but the card can't spend that money until you move it onto the card.
External network fees: if you send crypto from another wallet or exchange, that wallet or network may charge its own fee before the funds reach Solid. This is not a Solid fee and is outside our control.
Spending in USD
No fee. If a purchase is settled in US dollars, neither your card provider nor Solid charges anything, whatever country the merchant is in.
Spending in another currency
Card provider FX fee: 1%. Your card provider (Rain or Wirex) converts the purchase to USD and applies a 1% FX fee. It is built into the exchange rate you receive, not shown as a separate line, which is standard for card issuers. It is the same at every tier and on both card programs.
Solid FX fee: 1% at Core, 0.5% at Prime, free at Ultra. Charged to your balance after the purchase settles and shown as its own line in the transaction details. Move up a tier and it drops; reach Ultra and it disappears.
Both fees depend on the currency of the purchase, not the merchant's location. FX and cross-border fees are mutually exclusive: only one can ever apply to a transaction.
Spending in euros with zero fees (Wirex cards)
Way 1: a EUR balance. If your card is issued by Wirex, you can enable a EUR balance from the card page and fund it with EURC on Base. A euro purchase that your euro balance covers in full is taken one for one in euros: a €15.00 purchase takes €15.00, with no FX fee from anyone.
Way 2: soUSD with Credit mode. No EURC needed. Hold soUSD in Savings and switch your card to Credit mode: your euro purchases are covered from your soUSD with no FX fee, while your savings keep earning. Credit mode follows its own collateral and borrowing rules shown in the app.
Whole purchase or nothing. If your euro balance can't cover the full amount, even by a cent, the whole purchase is paid from your dollar balance at the rate at the time of payment, and the FX fees above apply, unless Credit mode is on with enough soUSD, in which case it is covered from your soUSD with no FX fee. One purchase is never split between the two balances.
Only purchases charged in euros count. A purchase in any other currency is converted by the card network at your provider's rate, FX fee included, exactly as described above. Nothing changes for those, even on a euro card.
Refunds come back in dollars, valued at the rate the purchase was charged at, even if you paid from your euro balance.

Fees Solid covers for you
Maintenance fee: none.
Cross-border fee: absorbed by Solid, not charged to you.
International transaction fee: covered by Solid, not passed through to you.
Why you still come out ahead
Every eligible card purchase earns cashback in USDC: 3% at Core, 4% at Prime and 5% at Ultra, up to your tier's monthly cap. That is more than the total FX cost at every tier. On a $100 purchase in euros, a Core member pays about $2 in FX fees and earns $3 back, ending up $1 ahead. At Prime it is about $1.50 in fees against $4 back, and at Ultra about $1 against $5 back. On USD purchases there are no FX fees, so the full cashback is yours. Cashback lands in your Savings and starts earning yield right away. See How does Solid Rewards work? for eligibility and monthly caps.
