What to know about Tether and USD Coin

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.

Sending and receiving USDT

The key choice is the network. USDT on TRON is popular for its low fees and speed, ERC20 is supported almost everywhere but costs more in gas, while Solana, TON and BEP20 are cheap alternatives. The recipient address must belong to the same network you send on, and you need the network's native coin (TRX, ETH, BNB…) to pay the fee from your own wallet.

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.

How USD Coin works

Like USDT, USDC exists on many blockchains — Ethereum, Solana, Polygon, Arbitrum, BNB Smart Chain and others. Circle mints and burns tokens as dollars enter or leave its reserves, which keeps the price close to 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 Tether to USD Coin

  1. Enter the USDT Optimism amount in the calculator (minimum 200 USDT Optimism) and click “Go to exchange”.

  3. Send exactly the specified amount of USDT Optimism on the Optimism network to the details shown in the order.
