What to know about USD Coin and Dai

USD Coin (USDC)

USD Coin (USDC) is a dollar stablecoin issued by Circle since 2018. Each token is backed by reserves held in cash and short-term US Treasuries, and the reserve composition is regularly reported by the issuer.

Sending and receiving USDC

Send USDC only on the network the recipient supports: an Ethereum address and a Polygon address may look identical but the funds end up on different chains. Fees are paid in the native coin of the network (ETH, SOL, POL…).

Dai

Dai (DAI) is a decentralized dollar stablecoin created by the Maker protocol (MakerDAO) in 2017 and now part of the Sky ecosystem. Unlike USDT or USDC, DAI is not issued against bank deposits: it is created by users who lock crypto collateral in smart contracts.

How Dai works

To mint DAI, a user deposits more collateral than the value of the DAI received. If the collateral falls in value, the position is liquidated automatically, which keeps DAI backed. Interest rates set by governance help hold the price near one dollar.

Optimism network

Optimism is an Ethereum layer-2 network. Addresses use the Ethereum format and fees are paid in ETH at a fraction of mainnet cost.

How to exchange USD Coin to Dai

Enter the USDC Optimism amount in the calculator (minimum 200 USDC Optimism) and click “Go to exchange”.
Enter your DAI wallet address on the Dai network and your contact details.
Send exactly the specified amount of USDC Optimism on the Optimism network to the details shown in the order.
Once the transfer is confirmed, Dai is sent to your address. You can track the order on its status page.

Exchange USDC Optimism to DAI

What to check before exchanging USDC Optimism to DAI

The recipient address must be on the Dai network: funds sent on another network may be lost.
The amount sent must be at least 200 USDC Optimism.
Copy the whole address and check the first and last characters after pasting.
Addresses on Ethereum, Arbitrum, Optimism, BNB Smart Chain and Polygon look the same (0x…): make sure the wallet shows Ethereum as the network.
To move DAI on Ethereum later, you will need a little ETH on the same address.
Funds go through an AML check; high-risk transfers may be held until the check is complete.
