STABLR exploit triggers EURR depeg and USDR collapse after a reported breach of the protocol’s minting infrastructure, sparking widespread panic across decentralized finance markets. Investigator ZachXBT first announced the hack and estimated losses to be around $10 million, as investors started exiting their trades due to concern over reserves.
The exploit had a significant impact on market confidence, as both stablecoins plummeted more than 20% below their intended values. EURR and USDR faced intense selling pressure across decentralized exchanges, while liquidity providers withdrew funds to avoid further exposure. The sharp decline added to mounting concerns surrounding stablecoin security, governance standards, and operational risks within decentralized finance ecosystems.

EURR depeg Deepens Stablecoin Market Losses
Blockaid stated that its monitoring systems detected an active exploit affecting the STABLR issuer, with roughly $2.8 million extracted during the attack. According to reports, the attack had occurred due to a vulnerability within the private key linked to the multisignature minting wallet of the project.
The attacker was able to inject itself within the multisignature wallet, replacing its owner nodes and minting 8.35 million USDR and 4.5 million EURR tokens. After minting the tokens, the attacker was able to swap them on decentralized finance exchanges. Under liquidity constraints, tokens amounting to about $10.4 million were swapped for just 1,115 ETH tokens.
With liquidity constraints, tokens with a total value of about $10.4 million were swapped for only 1,115 ETH, with a total value of nearly $2.8 million at the time. This further emphasized how governance flaws, rather than vulnerabilities within smart contracts, can cause problems within a decentralized finance ecosystem, leading to EURR depeg attacks.
Stablecoin Depegs Deepen Market Concerns
According to data obtained from STABLR’s website, the stablecoin EURR depegs to the euro, fell by 23% to around $0.88 in EUR/USD markets from an intended $1.15 peg. Meanwhile, USDR fell by almost 30% to $0.70 during the exploit period. Such depegs caused significant harm to both tokens’ values.
The exploit adds to a growing list of decentralized finance security breaches recorded throughout May. Some recent exploits were seen in THORChain, Verus Bridge, Echo Protocol, Polymarket, and Map Protocol, among others. There are rising threats connected with private key exploitation and governance flaws as well. At the time of writing, STABLR has not released any statement.
