Ten years after a landmark breach shook the Ethereum network, the entity once known as The DAO has been reconstituted as a security-focused fund overseeing about $130 million in assets. The move marks a shift from one of blockchain’s most infamous failures to a long-term effort aimed at strengthening Ethereum’s infrastructure.
The revival follows the 2016 exploit that drained roughly 3.6 million ETH—about one-third of The DAO’s holdings—and triggered a contentious chain split that led to the creation of Ethereum and Ethereum Classic.
Origins of the 2016 exploit
The DAO, developed by Slock.it under developer Jentzsch, raised approximately 12 million ETH, valued at $150 million at the time, from more than 11,000 participants. On June 17, 2016, attackers exploited a flaw in the “splitDAO” function, repeatedly withdrawing Ether before balances were updated.
About 3.6 million ETH was diverted into a child contract with a 28-day lock period, allowing time for a response. During that window, a group known as the White Hat Group moved remaining funds into secure contracts visible on-chain.
Chain split and regulatory fallout
The breach exposed a philosophical divide within the Ethereum community. One side argued that blockchain code should remain immutable, while another supported intervention to reverse unintended outcomes.
A hard fork was executed at block 1,920,000 on July 20, 2016, with approval from roughly 85% to 89% of participants. The move restored funds to original token holders, while the opposing chain continued as Ethereum Classic.
The episode also drew regulatory attention. In 2017, the U.S. SEC concluded that DAO tokens qualified as securities, setting a precedent that continues to shape digital asset oversight.
Structure and mission of the new dao fund
Today, around 75,000 ETH—sourced partly from unclaimed balances and curator holdings—forms the foundation of the new DAO fund. These assets are staked to generate yield, supporting grants focused on Ethereum security research, infrastructure, and incident response.
The fund operates under seven curators, including Ethereum co-founder Buterin and former MetaMask security lead Monahan, in coordination with the Ethereum Foundation. In its first grant round, it distributed $1 million in ETH to 134 projects, selected from more than 250 applicants, with additional support from Wintermute.
Market conditions and funding model
The fund’s valuation has declined alongside ETH prices, falling from about $220 million earlier in the year to roughly $130 million as ETH trades near $1,750. Broader market pressure has also weighed on major assets, with Bitcoin and Ethereum both posting recent declines.
Despite volatility, the fund’s staking-based structure is designed to generate an estimated $8 million annually, creating a sustainable pool for ongoing security development independent of short-term price swings.
Rising threats reshape security priorities
Recent data underscores the urgency of the initiative. Digital asset breaches totaled $3.4 billion in 2025, with a single February incident accounting for nearly half of that figure. Through mid-April, decentralized finance losses alone exceeded $750 million.
Analysts note a shift in attack patterns. Earlier exploits often relied on code vulnerabilities such as reentrancy bugs, while newer incidents increasingly involve phishing, operational failures, and compromised signing tools. High-profile cases, including losses tied to cross-chain bridges and oracle systems, point to more complex, multi-stage attack strategies.
A long-term approach to ecosystem resilience
The DAO fund reflects a broader evolution in Ethereum’s approach to security, aligning with development priorities that emphasize resilience and risk mitigation. Its use of staking yields and community-driven grant allocation models, including quadratic funding mechanisms, signals a maturing governance framework.
By redirecting capital once lost in a historic exploit toward strengthening the network, the initiative highlights a shift from reactive fixes to proactive defense—an approach shaped directly by the lessons of 2016.
