StablR's USD stablecoin USDR traded around $0.63, about 37% below its peg, while EURR was roughly 22% under parity after the issuer confirmed an exploit. The incident involved unauthorized minting of 8.35 million USDR and 4.5 million EURR, with the attacker reportedly netting 1,115 ETH as liquidity on DEX pools was drained.

StablR said it identified an exploit on Sunday after an attacker used control of a 1-of-3 multisig setup to mint unbacked EURR and USDR and sell them on DEX markets. On May 24, EURR fell to $0.85 while USDR traded around $0.64 after touching $0.40, with onchain estimates citing about 1,115 ETH (about $2.8 million) extracted and as much as $10.4 million in unbacked issuance.

The StablR incident undermined stablecoin confidence after attackers abused a low-threshold 1-of-3 multisig to gain effective minting authority. The breach enabled unauthorized issuance of about 8.35 million USDR and 4.5 million EURR, which later saw EURR fall toward $0.86 and USDR drop below the $0.80 area. Attackers then swapped nearly $10.4 million in newly minted tokens and extracted around 1,115 ETH amid deteriorating liquidity.

On May 24, 2026, Zerohash Europe said it became the first firm operating under the EU's MiCA regime to also obtain a full Electronic Money Institution (EMI) license, enabling wider regulated stablecoin and brokerage services across Europe.

Intesa Sanpaolo reported $235 million in crypto assets as of March 31, 2026, rising from $100 million at end-2025, while several European peers rolled out trading, custody, and stablecoin initiatives. BBVA enabled 24/7 Bitcoin and Ethereum trading in its Spanish app, BPCE opened crypto access via Hexarq with a stated reach of 12 million clients, and a 12-bank group formed Qivalis to pursue a euro-denominated stablecoin.

StablR's EURR and USDR stablecoins fell off-peg during an ongoing exploit that Blockaid said was likely caused by a compromised private key tied to the minting multisig. Blockaid estimated about $2.8 million has been extracted after the attacker minted 8.35 million USDR and 4.5 million EURR and swapped the tokens for 1,115 ETH amid thin liquidity.

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.
