USDD has launched the STRX function, which is very good. STRX is similar to STETH and is a TRX with staking income in the Tron network. Its annualized interest rate is 9% -15%. Holding STRX staking to lend USDD stablecoins is equivalent to borrowing money and arbitrage. It is very suitable for those who hold TRX and are unwilling to sell but still need stablecoins!
