The ongoing exploit affecting StablR has led to significant depegging of its Euro and USD stablecoins, with EURR dropping 23% and USDR declining by 30%. As reported by blockchain security firm Blockaid, the incident is linked to a compromised private key within a multisignature account, where a weak 1-of-3 threshold was utilized. This breach allowed an attacker to mint approximately 8.35 million USDR and 4.5 million EURR, leading to the collapse of the stablecoins' value.
Currently, StablR's euro stablecoin, which had a market cap of $14 million, plummeted from a $1.15 peg to $0.88. Similarly, the USDR stablecoin, valued at $11 million, fell to $0.70. The attacker was able to exchange the minted tokens worth around $10.4 million for only 1,115 ETH, approximately $2.8 million, due to low liquidity in the market.
May has been particularly challenging for the crypto sector, with numerous exploits reported, including significant breaches involving THORChain and Polymarket. StablR, which focuses on regulatory compliance and transparency, is still under scrutiny following this incident.
