What to know about USD Coin and Tether Gold

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.

Ethereum (ERC20) network

ERC20 is the token standard on Ethereum. It is supported by almost every wallet and exchange, but the fee (gas) is paid in ETH and grows when the network is busy.
