What to know about Tether and Sui

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.

Sui uses an object-centric data model and the Move programming language, which allows many transactions to be processed in parallel. Validators run Delegated Proof of Stake. The maximum supply is 10 billion SUI.
