EURR, the euro-pegged stablecoin from StablR, dropped about 20%, after which USDR no longer traded in its usual relationship with EURR. The move followed claims of a suspected smart-contract exploit, with on-chain investigator ZachXBT flagging an incident estimated at $3 million. The divergence highlights stress in liquidity and redemption confidence that typically keep stablecoins near their pegs.

On-chain investigator ZachXBT said two contracts tied to European stablecoin issuer StablR may have been drained in a live exploit worth about ~$10M, pushing EURR and USDR more than 20% below their pegs. He identified the main wallet address and listed seven additional addresses he linked to the incident. Roughly two hours after his first alert, he said he helped freeze a six-figure amount while the exploit was still ongoing.

Kevin Warsh was sworn in as chair of the US Federal Reserve on Friday, and analyst Lawrence Lepard argues Warsh is more likely to cut interest rates than raise them. Traders are positioned the other way: the federal funds target rate is 350–375 basis points, and futures imply nearly 68% odds of a 25 basis points (BPS) hike or more by December 2026. The debate has kept investors focused on how a policy shift could affect risk assets such as Bitcoin and other crypto.
