StablR Stablecoin Under Attack Causes EURR and USDR to Decouple Significantly
The stablecoin issuer StablR has been under sustained attack, leading to severe decoupling of its euro stablecoin EURR and dollar stablecoin USDR.
The attacker is suspected of obtaining the private key of one owner of the minting multi-signature account, replacing the administrator under a 1/3 signature mechanism, and additionally minting 8.35 million USDR and 4.5 million EURR.
The attacker then exchanged tokens worth approximately $10.4 million on a DEX, profiting around $2.8 million. EURR briefly fell to around $0.88, while USDR dropped to around $0.7.
Blockaid pointed out that the core issue of the incident lies in the failure of key management and governance mechanisms, rather than a smart contract vulnerability.

StablR previously relied on multi-signature governance to issue euro and dollar stablecoins. This attack continues a trend in the stablecoin sector where private key leaks or governance design flaws have been exploited, similar to the 2022 Ronin bridge attack and several smaller stablecoin projects that lost multi-signature control.
In terms of capital flow, the attacker quickly minted and cashed out through a low-barrier multi-signature mechanism, draining liquidity from the protocol and prompting user funds to shift from StablR to stronger custodial stablecoins like Circle USDC and Tether. StablR faces liquidity depletion and reputational damage, while compliant institutional stablecoin issuers benefit from the influx of risk-averse capital.
Similar to past collapses of euro/fiduciary stablecoins due to weak governance, the current stablecoin market is transitioning from early experimental multi-signature issuance to a controlled phase of strict institutional custody.
Essentially, this represents a restructuring of the industry driven by regulatory changes. The single point of failure in multi-signature governance has altered the security pricing structure of stablecoin issuance, as the low 1/3 signature threshold allows for unlimited minting upon key leakage, concentrating capital from weakly governed small stablecoins to mature stablecoins with strong audits, insurance, and institutional backing, achieving a structural integration of the industry from decentralized high risk to centralized compliance.

The simpler the multi-signature, the lower the attack cost, and the faster the collapse.
The real risk of stablecoins has never been the code, but the person holding the private key.
The weaker the governance mechanism, the more resolute the capital flight.
