About USD Coin (USDC)

USDC is a dollar stablecoin issued by Circle and redeemable one to one for US dollars. It is common on Ethereum and its layer-2 networks, and on Solana. OP Mainnet is an Ethereum layer-2 with low fees.

Like USDT, a USDC payment keeps its dollar value from checkout to your balance. Many businesses prefer to hold USDC, so you can also convert incoming coins to it automatically.

How a USDC on Optimism payment works

1
You create an order in USD
From your store plugin, a payment link or one API call.
2
The USDC amount is locked
Converted at the live price once, when the order is created. It never changes afterwards.
3
The customer pays a fresh address
A deposit address made for this order only, with a QR code on Optimism.
4
You get a signed webhook
When the payment is credited (after 20 confirmations), your balance goes up and your system is told.
