<p>The project said contributors secured the vsdCRV backing on Ethereum mainnet and closed the vsdCRV bridge. Stake DAO said this contained the incident to Arbitrum and stopped the attacker from seizing the mainnet backing.</p>

<p>Stake DAO said, “preliminary investigation indicates an unauthorised party (attacker) minted vsdCRV on Arbitrum.” The statement followed earlier reports that security firms had tracked a large unauthorized mint tied to the protocol’s vsdCRV token.</p>

<p>As crypto.news <a href="https://crypto.news/defi-exploit-hits-stake-dao-as-attacker-swaps-vsdcrv-for-eth/" rel="noopener noreferrer nofollow">reported</a> yesterday, Blockaid said the attacker minted more than 5.4 trillion vsdCRV on Arbitrum and began swapping tokens for ETH. PeckShield also tracked part of the funds moving into 43.78 ETH before being bridged to Ethereum.</p>
<p>The latest update narrows the risk area. Stake DAO said contributors moved quickly to protect the vsdCRV backing on mainnet. The team added that there were “no funds seizable by the attacker” from that backing.</p>
<p>Stake DAO also closed the vsdCRV bridge. That step was aimed at stopping the exploit from spreading beyond Arbitrum and limiting further damage while the review continues.</p>
<h2 class="wp-block-heading" id="strong-key-products-remain-unaffected-strong"><strong>Key products remain unaffected</strong></h2>
<p>Stake DAO said its current assessment shows that Boosted yields, Liquid Lockers, Votemarket and Stake DAO lending on Morpho were unaffected by the incident.</p>
<p>The statement matters for users because those products form a major part of Stake DAO’s yield and governance services. The project did not report any direct issue affecting those products in its latest update.</p>
<p>Still, the team did not say the full review had ended. It described the findings as current and preliminary, meaning the final scope could change if security teams find new information.</p>
<p>Stake DAO said law enforcement remains involved and security partners are assisting the review. The project also said it would share more information later.</p>
<h2 class="wp-block-heading" id="strong-arbitrum-asdcrv-market-is-being-sunset-strong"><strong>Arbitrum asdCRV market is being sunset</strong></h2>
<p>Stake DAO said the Arbitrum asdCRV Llamalend market is being sunset after the incident. It told crvUSD depositors that they can move their funds to other Llamalend markets.</p>
<p>That step gives users a clearer route to reduce exposure to the affected market. It also shows that the protocol is taking a product-level response, not only a technical bridge response.</p>
<p>The update did not state that asdCRV itself was <a href="https://crypto.news/kelp-attack-spreads-risk-across-defi-293m-lost/" rel="noopener noreferrer nofollow">exploited</a>. The main confirmed issue remains the unauthorized minting of vsdCRV on Arbitrum.</p>
<p>For now, the main focus remains on user safety, market exits and the ongoing investigation. Stake DAO’s next updates will be important for final loss figures, recovery actions and any further product changes.</p>
