What to know about Tether Optimism and Tether Arbitrum

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.

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.

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.
