MiCA Compliant Euro Stablecoin Depegs to $0.85 After 1-of-3 Multisig Exploit Drains Millions
USDR chart via markets. on May 24, 2026. StablR markets EURR as a euro-pegged and USDR as a dollar-pegged token, both positioned as regulated instruments under the European Unions Markets in Crypto-Assets (MiCA) framework with proof-of-reserves disclosures. The company bridges traditional finance and markets. Security firm Blockaid flagged the incident publicly, describing the 1-of-3 threshold as a “key management and governance failure.” Many observers commented that a single compromised key should not carry the power to issue currency, yet allegedly StablRs configuration allowed exactly that. “EURR issuance was controlled by a 1/3 multisig implementation (not Safe) whose signers the alleged attacker replaced,” one X account wrote on Sunday. “They then continued to transfer and mint new EURR to sell on secondary markets, leading to a secondary market depegs. It is worth noting that StablR has previously stated they use Tethers Hadron tokenisation platform to power EURR issuance.” The individual added: “If this is an exploit, it is the first of its kind for a MiCA compliant .” While StablR acknowledged the exploit through its official X accounts, no detailed technical postmortem or recovery timeline was available as of the time of writing. Community analysts on X debated loss estimates ranging from $2.8 million to $10.4 million
