On May 24, 2026, one of StablR's three multisig keys was compromised. The attacker minted 8.35M USDR and 4.5M EURR against zero collateral and dumped them for ~$2.8M in ETH.

According to on-chain investigator ZachXBT and security firm Blockaid, two contracts linked to European stablecoin issuer StablR (EURR and USDR on Ethereum) were suspected of being exploited. The attacker’s funds appear to have come via CCTP on Noble. ~$2.8M+ extracted so far, causing both stablecoins to depeg significantly.
