Bank SMS notification of the arrival, but 10 minutes later it becomes negative, my heart stopped at that moment.
I was holding the remaining 30,000 dollars, my hands trembling as I exchanged it for USDD.
3 seconds confirmation on the chain, 28800 block time lock welded shut.
That night I didn't stay up late, I slept until dawn—money is still there, the address can't be moved, no one can withdraw.
USDD upgrades 'arrival' to 'locked'.
Traditional USDT relies on bank delays, and the scammers' window is wide open;
USDD relies on contracts that are set in stone, block confirmations enter a 24-hour cold storage, no human can press the return key.
What's even harsher is that the locking period has an annualized interest rate of 8%, and the more chaotic the market, the higher the interest, even lying flat can recover losses.
In one sentence:
USDT means 'Seeing is believing', USDD means 'Locked is stable'.
From now on, if anyone asks me to receive USDT, I will directly blacklist them—On-chain USDD, arrives and mines instantly, scammers become unemployed.
