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.

Where to store Tether

USDT can be held in any wallet that supports the chosen network. Check that the wallet shows the official USDT contract, because fake tokens with the same name exist.

Polygon network

Polygon PoS is an Ethereum-compatible network with addresses in the same 0x format. Fees are paid in POL and usually cost a fraction of a cent.

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.

The amount sent must be at least 200 USDC Polygon.
