Solid has switched on euro-denominated cards, letting users spend in euros across the EU without a foreign exchange fee. The company confirmed the rollout in an official post on X, describing two funding paths: deposit EURC directly, or hold soUSD and turn on Credit mode. For anyone whose daily spending is in euros, this removes the conversion step that normally sits between a dollar-denominated balance and a euro checkout.
Euro balances, not just euro checkouts
Until now, spending euros from a crypto card usually meant holding a dollar stablecoin and paying a conversion each time a merchant charged in euros. Solid's euro cards hold value in euros from the start. A EURC deposit funds the card as a euro balance, so a 40-euro grocery run draws down 40 euros rather than converting from USDC at the point of sale. That is the practical meaning of the "no conversion, no FX" line in the announcement for EU residents.
This is a regional feature by design. The benefit applies to euro-area spending, where matching the balance currency to the billing currency is what kills the markup. Someone funding in euros and then travelling outside the eurozone would still hit a conversion at the till, so the zero-fee claim is specific to euro purchases, not a blanket no foreign exchange markup on everything.
Two ways to fund a euro card
The first path is straightforward: deposit EURC, the euro stablecoin, and spend it. Balance and billing currency line up, and there is nothing to convert.
The second path is a credit model. Hold soUSD, Solid's yield-bearing dollar token, keep it as collateral, and enable Credit mode to spend against it. That lets holders keep earning on the deposit while spending, rather than selling it to fund purchases. It also introduces the usual mechanics of borrowing against a crypto position: the collateral carries price and liquidation considerations, and any borrow cost reduces the net yield. The headline euro purchase may carry no FX fee, but the economics of spending borrowed dollars against a dollar deposit to settle a euro bill are not the same as simply spending euros you already hold.
The zero-fee claim, read in full
"Zero fee" on a card rarely means zero cost end to end. The disclosed FX fee is only one layer. Network spread from the card scheme, any crypto-to-fiat conversion at settlement, and on-chain gas for topping up a balance all sit outside the advertised number. Solid's euro cards genuinely cut the EUR-to-EUR conversion step, which is the most visible markup for euro spenders. The parts worth checking before leaning on the card are the soUSD borrow rate in Credit mode and whether any spread appears when funds move between soUSD and the euro balance.
For euro-area users who already hold EURC, the simplest read is the most favorable one: fund in euros, spend in euros, skip the conversion. For soUSD holders, the card is a way to spend without unwinding a yield position, with the trade-offs that come with any collateralized line of credit.
Overview
Solid has launched euro-denominated cards for EU spending with no FX fee on euro purchases. Cardholders can fund with EURC for a plain euro balance, or hold soUSD and use Credit mode to spend against collateral while keeping the deposit invested. The FX saving is real for euro-area spending specifically. The costs to watch are the Credit-mode borrow rate and any spread on moving between soUSD and euros, neither of which shows up in the headline "zero FX" figure.
