Do I end up holding crypto?

No. The conversion happens as part of settlement, so what lands in your account is euros. You don't operate a wallet, you don't hold a position, and there's nothing to sell at month end.

Who takes the price risk between quote and confirmation?

The rate is fixed and shown to the customer before they confirm, and that same rate is what appears on the receipt and in your settlement. The order total in euros is the number you were always going to receive.

Which networks are supported?

Ethereum, Base, and Solana, behind a single toggle. Customers pay on whichever their wallet lives on — the merchant side of the configuration is identical either way.

How does a USDC refund work?

It's issued against the order like any other refund, full or partial, with a required reason. It travels back as the euro settlement of the original payment rather than as a token transfer, so the accounting stays in one currency on both legs.

/// Method · Crypto

USDC in, euros out.

USDC sits on the same checkout as cards and wallets. The customer pays on whichever network their wallet lives on; the amount is priced at a rate shown before they confirm, and what reaches your account is euros in the same payout as your card takings. You never hold a token position, and your accountant never sees a second currency.

SETTLE
The amount converts and pays out in EUR alongside every other method.

/// 01

What the customer sees

USDC as one of the payment options, not a separate page or a redirect to a crypto site. Picking it shows the amount in USDC, the network choice, and the rate being applied — before anything is sent. The receipt they get afterwards states the conversion in one line, so there's no ambiguity about what was paid.

/// 02

What you receive

Euros, in the same payout as your card takings, against the same order reference. The conversion happens before settlement rather than after, which is what keeps you out of holding a position: at no point does accepting a stablecoin turn you into a business with a treasury function or a wallet to secure.

What it takes to switch on

One toggle covers all three networks — the customer picks the one their wallet is on and your configuration doesn't change. The settlement panel beside it states the deal plainly: auto-convert to EUR, paid out to your named account at the daily payout time.
