Accept payments · EURC

Accept EURC payments.

Invoice in the currency you sell in, and let your customer pay in EURC. We give the invoice its own address on the chain they choose, watch it, and send you a signed webhook when the payment is final. Circle's euro, the counterpart to USDC. 🔴 It tracks the EURO, not the dollar — an invoice priced in USD and paid in EURC still settles at the euro rate at the moment of payment.

EURC on Ethereum: Gas here is the highest of any chain on this list, so a payment has to clear a minimum amount to be worth collecting. The checkout shows that minimum to your payer before they choose Ethereum, and every other chain here is cheaper.

Taking a EURC payment.

Create the invoice
One POST with an amount, a pricing currency and your own reference. You get back a checkout URL, one payment address per chain, and a locked amount in every coin you accept.
They pay, at a rate that stays honest
Your customer is never asked to commit to a chain first — one address serves every EVM chain, so whatever arrives is attributable. Stablecoins are quoted once. A volatile coin is re-quoted every two minutes, and the figure it replaces is still honoured for five, so nobody who did as they were told is told they underpaid.
You get a signed webhook
HMAC-SHA256, retried for about 46 hours, replayable from the dashboard. The payment is credited to your balance per asset.

What you do not have to do.

Hold a EURC wallet, or guard a seed phrase for one. No address here has a private key.
Keep gas on hand. We pay the network fee on every chain EURC settles on.
Ask your customer to make an account. The hosted checkout needs nothing from them but a payment.
Watch every block yourself, or reconcile a reorg by hand.
