USDC vs EUR for group expenses: what changes

Spliz settles in USDC, a US-dollar stablecoin, not in euros. If your group thinks in euros, that raises a fair question: what actually changes? In short, you read amounts in your own currency, but the money that moves is USDC, and there is a small dollar-euro gap to be aware of. Here is the honest version.

What is USDC, and why settle in it?

USDC is a digital dollar: one USDC is redeemable for one US dollar, so it does not swing in value. Spliz settles in it because it moves instantly, on-chain, between wallets, with no bank in the middle. That is what makes a whole group clear in seconds for cents.

Can you still see amounts in euros?

Yes. The app shows amounts in your local currency for readability, so a French group reads euros. The display is a convenience; the value that actually settles is the USDC amount. When you sign, you are approving the USDC, not a euro figure that gets converted somewhere.

So where is the catch?

The dollar-euro exchange rate. Because settlement is in dollars, a euro amount you logged can be worth slightly more or less in USDC by the time you settle, as the rate moves. For everyday group spending the gap is small, but it is real, and we would rather say so than pretend the two currencies are the same thing.

Do you need to convert euros to USDC?

You settle from the USDC you hold, so the group works best when people already hold, or want to hold, USDC. Spliz does not promise more than it ships: it is non-custodial, it never takes euros into an account, and it settles what is in your own wallet. If you do not hold USDC yet, that is the one thing to sort out first.

The short version

• Settlement is in USDC; the euro figure is a display convenience.
• There is a small dollar-euro FX gap, by design and stated plainly.
• You settle from USDC you hold; Spliz never holds euros for you.

Read in euros, settle in dollars. We would rather name the gap than hide it.
