Summary

StablR halted minting and redemptions for its USDR and EURR stablecoins after attackers exploited a 1-of-3 Ethereum multisig wallet weakness to mint about $13.5 million in unauthorized, unbacked tokens, with roughly $2.8 million reportedly cashed out. In a related development, Oobit said its compliance team froze a six-figure amount of EURR tied to the exploit when the funds attempted to leave through its Tether-backed mobile wallet, adding that no user funds were affected and its own systems were not breached. Following the suspension, USDR recovered to around $0.994 while EURR fell to about $0.548, showing sharply different market responses.

Terms & Concepts
  • 1-of-3 multisig: A wallet setup where any one of three keys can approve transactions, offering limited protection if one key is compromised.
  • Minting: The process of creating new crypto tokens on a blockchain according to a project’s rules or smart contracts.
  • Compliance team: An internal unit that monitors transactions for legal and risk issues, including suspected illicit flows, and can coordinate freezes or reporting actions.
