Chainalysis Expands Web3 Security With Hexagate Access

Chainalysis has reported that more than $2.17 billion was stolen from crypto services during the first half of 2025, underscoring the growing urgency to protect decentralized finance and Web3 protocols. The firm has emphasized that threats now extend beyond simple hacks to include operational failures, governance-based attacks, and complex financial exploits. In response, Chainalysis has highlighted the need for proactive prevention measures, including stronger data security infrastructure, advanced tooling, and deeper collaboration across the blockchain ecosystem.

The company has framed security as a foundational requirement for the sustainability of Web3. As the value flowing through decentralized protocols increases, attackers have become more sophisticated, making reactive approaches insufficient. Chainalysis has indicated that the ecosystem must shift toward prevention-first strategies that can identify and mitigate threats before they result in losses.

Partnering With Blockchain Foundations

To strengthen on-chain security, Chainalysis has announced partnerships with multiple blockchain foundations. Through these collaborations, the firm aims to secure not only individual protocols but also the underlying blockchain networks themselves. A central element of this initiative is providing developers with free access to a customized version of Hexagate, tailored for teams building on participating networks.

Hexagate is positioned as a runtime security platform specifically designed for on-chain environments. Chainalysis has explained that the platform continuously monitors blockchain activity to detect active attacks and enables teams to intervene before funds are lost. This approach differs from traditional cybersecurity tools, which typically focus on protecting servers, databases, and cloud infrastructure rather than smart contracts and on-chain assets.

Addressing Gaps in Traditional Security

According to Chainalysis, legacy security solutions are not equipped to safeguard decentralized systems where logic and value are embedded directly in smart contracts. Hexagate is designed to fill this gap by protecting transactions, contracts, and digital assets at the protocol level. This capability is particularly important as blockchain security teams are tasked with protecting critical infrastructure and large treasuries that can become high-value targets.

Chainalysis has described the responsibility of these teams as mission-critical, noting that even a single exploit can cause severe financial damage and permanently erode user trust. As a result, the company views on-chain security as the most challenging and consequential frontier for Web3 builders.

Supporting Developers at No Cost

Building a Web3 protocol requires balancing innovation, user experience, token economics, onboarding, and scalability. Chainalysis has stressed that despite these competing priorities, security remains the most essential component. Through its foundation partnerships, the firm is offering eligible projects tailored access to Hexagate at no cost, lowering the barrier for developers to implement advanced security infrastructure from the outset.

Projects developing on select networks may qualify for this support, including those building on Base, Avalanche, MegaETH, and Plasma. Additional networks such as Polygon, Cronos, Immutable, and others are also involved in the broader partnership initiative. By removing cost constraints, Chainalysis aims to ensure that smaller teams and early-stage projects can still adopt enterprise-grade security practices.

Building a More Resilient Ecosystem

The broader goal of the initiative is to create a more resilient Web3 ecosystem. Chainalysis has indicated that proactive protection combined with clear visibility into ecosystem-wide security conditions can enhance trust and transparency for all participants. By securing individual protocols alongside core chain infrastructure, the partnerships are intended to reduce the likelihood that exploits affecting one project will spread and harm the wider network.

The firm has also pointed to a rise in malicious on-chain activity, both in frequency and complexity. Phishing attacks and social engineering schemes have been identified as particularly serious threats, with adversaries continuously adapting their tactics. Chainalysis has concluded that defenses must evolve at the same pace, relying on real-time monitoring and collaboration rather than isolated, reactive measures.

Through expanded access to Hexagate and closer cooperation with blockchain foundations, Chainalysis is positioning security as a shared responsibility and a prerequisite for the next phase of Web3 growth.
