Arbitrageurs took advantage of USDT deposit
Lookonchain noticed that immediately after the deposit, an investor under the nickname czsamsun.eth shorted the coin on the Aave V2 DeFi protocol. He borrowed 31,544,278 USDT and immediately exchanged it for 31,475,408 USDT at a rate of $0.9978.
Another user took advantage of the drop in the stablecoin rate by borrowing USDC to buy USDT and repay the loan in the coin.
