During yesterday’s real-estate-backed U.S. dollar stablecoin Real USD (USDR) crisis, a trader appears to have swapped 131,350 USDR for 0 USD Coin (USDC), resulting in a complete loss on investment.

According to the October 12 report by blockchain analytics firm Lookonchain, the swap occurred on the BNB Chain through decentralized exchange OpenOcean, at a time when USDR depegged from par value by nearly 50% due to a liquidity crunch. A maximal extractable value (MEV) bot subsequently picked up the discrepancy, netting a total of $107,002 in profits through an arbitrage trade. 

During periods of poor liquidity, slippage on DEXs can reach as high as 100%. In September 2022, Cointelegraph reported that a trader attempted to sell $1.8 million in Compound USD (cUSDC) through Uniswap DEX V2 and only got $500 worth of assets in return. An MEV, too, in this incident, performed an arbitrage trade before its over $1 million in profits were hacked just hours later. 

On October 11, USDR depegged after users requested over 10 million stablecoins in redemptions. Despite being 100% backed, less than 15% of its then $45 million in assets were backed by liquid project tokens TNGBL, with the remaining backed by illiquid tokenized real-estate assets.

As narrated by analyst Tom Wan, the tokenized assets were minted on the ERC-721 standard, which could not be fractionalized to create liquidity for investor redemptions. In addition, the underlying homes could not be immediately sold to meet investors’ withdrawal requests. Altogether, the Real USD Treasury could not meet the redemptions, leading to a collapse in investors’ confidence.
