Two contracts linked to European stablecoin issuer StablR’s EURR and USDR stablecoins may have been exploited, according to blockchain investigator ZachXBT, who flagged the incident on Saturday through his official channel.

The attacker’s wallet appears to have been funded via the Cross‑Chain Transfer Protocol (CCTP) on Noble, with estimated losses exceeding $10 million.

StablR is a European stablecoin company headquartered in Malta. The firm issues EURR, which is pegged to the euro, and USDR, which is pegged to the US dollar. StablR says it is focused on a compliant and transparent stablecoin infrastructure for merchants, institutions, and payment networks.

The company raised €3.3 million in seed funding in 2023 with backing from Deribit, Maven 11, Theta Capital, Folkvang, and Blocktech. In 2024, Tether announced a strategic investment in the company as part of efforts to support regulated stablecoin growth in Europe.

In a statement released on May 24, StablR confirmed the exploit and said efforts are underway to contain the incident and minimize its impact. The company added that it would share verified information and outline next steps as soon as more details become available.

Security update: We have identified an exploit affecting StablR and are actively working to contain it and minimize impact.

Protecting our users and your funds is our top priority.

We'll share verified details and next steps as soon as possible.
