The USDR liquidity crunch

USDR, a stablecoin backed by real estate, faced a liquidity crisis when users sought redemptions. However, it was discovered that only a small percentage of its assets were backed by liquid tokens, with the majority relying on illiquid tokenized real estate assets. These assets were difficult to sell quickly, leading to a liquidity problem and causing a lack of confidence among investors.

The costly DEX swap

During the liquidity crisis, a trader attempted to withdraw their USDR holdings by swapping it for USDC on the BNB Chain through the decentralized exchange OpenOcean. However, due to the severe depegging of USDR, the trader received 0 USDC in return for their 131,350 USDR. This resulted in a significant loss on their initial investment, highlighting the risks involved in DeFi trading.

A MEV bot took advantage of the price discrepancy and profited $107,002 through an arbitrage trade.
