What to know about USD Coin and Tether
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…).
Tether (USDT)
Tether (USDT) is the largest stablecoin: a token designed to stay at one US dollar. It was launched in 2014 by Tether Limited, which issues USDT against reserves that consist mostly of cash equivalents and short-term US Treasury bills.
What Tether is used for
USDT is used to park funds without price volatility, to settle trades, to move dollars across borders and to pay for services. It is the most traded asset in crypto and the most common way to lock in profits after selling other coins.
Arbitrum One network
Arbitrum One is an Ethereum layer-2 network. Addresses use the Ethereum format, fees are paid in ETH and are much lower than on the Ethereum mainnet.
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.

What to check before exchanging USDC Arbitrum to USDT Optimism

- Addresses on Ethereum, Arbitrum, Optimism, BNB Smart Chain and Polygon look the same (0x…): make sure the wallet shows OP Mainnet (Optimism) as the network.
- To move USDT on OP Mainnet (Optimism) 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.
