Compound Tether or cUSDT is a variant of the USDT that has been integrated into the Compound protocol. Compound is a decentralized lending and borrowing platform built on the Ethereum blockchain. cUSDT is an interest-bearing token representing the ownership of USDT deposited into the Compound protocol. When users supply their USDT to the Compound protocol, they receive an equivalent amount of cUSDT in return. The key feature of cUSDT is that it allows users to earn interest on their USDT holdings by lending them out on the Compound platform. As borrowers borrow assets from the protocol, they pay interest, which is then distributed to the users who have supplied their assets as collateral. This enables USDT holders to passively earn interest on their holdings while still retaining ownership of their assets.
