Chainstack

Profile narrative

Chainstack operates as a blockchain infrastructure platform that provides managed node hosting, API access, and developer tooling for building and scaling Web3 applications. The service supports multiple blockchain protocols including Ethereum, Polygon, BNB Chain, Avalanche, Arbitrum, and Optimism, allowing customers to deploy dedicated or shared nodes without managing underlying infrastructure. Its offerings target software developers, startups, and enterprises seeking reliable access to blockchain networks for decentralized applications, DeFi platforms, NFT marketplaces, and analytics services. The platform emphasizes ease of integration through standardized APIs, monitoring dashboards, and automated scaling features designed to reduce operational overhead for engineering teams.

The company has established a global footprint with data centers distributed across major cloud regions to ensure low-latency connectivity and high availability for its users. While specific customer counts and revenue figures are not publicly disclosed, Chainstack serves a range of clients from individual developers to institutional teams building production-grade blockchain solutions. Its positioning focuses on abstracting the complexity of node operations, offering both elastic shared endpoints and dedicated enterprise-grade deployments with service-level agreements. The organization has raised venture funding from investors focused on Web3 infrastructure, though detailed ownership structure remains private.

On October 26, 2026, Chainstack disclosed a cybersecurity incident in which an unauthorized actor gained access to its production systems through a compromised third-party component. The intrusion, which began on the same date, was detected on October 31 and contained that day, resulting in the exposure of customer data and password hashes. Threat intelligence analysis attributed the campaign to a China-linked group tracked as ARTEX, marking a targeted supply-chain attack against the platform's infrastructure. The company initiated incident response procedures, notified affected users, and engaged external forensic investigators to assess the full scope of the breach.
