StablR suspended USDR and EURR business due to hacker attack

According to CoinDesk, StablR has suspended the minting and redemption of USDR and EURR due to a vulnerability in the Ethereum 1-of-3 multi signature wallet exploited by hackers, and has requested exchanges to stop trading and withdrawals of the two currencies. After breaking through a single private key, the attacker set themselves as the administrator and issued approximately 8.35 million USDR and 4.5 million EURR, with an anchor price of approximately 13.5 million US dollars, and actually cashed out approximately 2.8 million US dollars. The incident resulted in insufficient collateral for two coins, causing USDR to drop to around 0.994 US dollars and EURR to drop to around 0.548 US dollars.
