KuCoin launched KCUSD, a yield-bearing product backed by real-world assets including tokenized U.S. Treasury securities, allowing eligible retail, high-net-worth and institutional users to earn daily returns on stablecoin balances. Users can subscribe from 1 USDT, USDC or USDG without a fee and redeem in the asset originally used for subscription. KCUSD's dynamic base APR can reach 4%, while qualifying new deposits during the launch period can earn promotional APR of up to 6%; returns are credited daily and automatically added to balances. KuCoin plans to permit KCUSD to be used as collateral for margin and trading, but that capability is not active and the exchange has given no launch timetable. The company has also not publicly detailed custody arrangements or independent verification for supporting assets, while returns can change with market conditions and asset performance.
