Chainstack

Chainstack is a managed blockchain infrastructure provider that gives development teams production-grade access to RPC nodes, archive data, and real-time streaming services across more than 70 blockchain protocols. Founded in 2018 and headquartered in Singapore with a second office in Burlington, Massachusetts, the platform was built to solve a problem co-founders Eugene Aseev and Laurent Dedenis identified early in the Web3 build cycle: DevOps teams lacked the tooling to reliably scale blockchain applications, while enterprises needed integrated solutions that abstracted away node operations entirely. The company's current CEO is Nils Hueneke, who previously led WebPros and served as CEO of Plesk.

How It Works

Chainstack abstracts the complexity of running and maintaining blockchain nodes behind a managed API layer. Developers sign up, select a network and node type, and receive an HTTPS or WebSocket endpoint within minutes. Requests are routed to the nearest available region automatically, keeping latency low and availability high. Under the hood, the company runs bare-metal infrastructure with encrypted endpoints, automated threat mitigation, and DDoS protection. Chainstack holds SOC 2 Type II and ISO/IEC 27001 certifications and publishes a 99.99% uptime SLA.

For teams that cannot use shared or managed infrastructure due to compliance or performance requirements, Chainstack offers dedicated nodes and, since May 2026, a self-hosted deployment option that lets teams run Chainstack-managed nodes on infrastructure they fully own.

Key Features

Node types and access tiers. Chainstack distinguishes between Global Nodes (shared, globally routed), Dedicated Nodes, Unlimited Nodes (flat-fee requests-per-second tiers starting at $149 per month), and Trader Nodes tuned for low-latency execution. Archive access is available for full historical data lookups. A free Developer plan provides immediate access without requiring a credit card.

Pricing model. Chainstack bills on a request-unit (RU) basis where one real API call costs one RU, regardless of the JSON-RPC method used. This differs from competitors who apply per-method cost multipliers—Alchemy charges up to 26x and QuickNode up to 20x for heavier methods—making Chainstack's cost predictable for teams with diverse call patterns.

Real-time streaming. For use cases requiring sub-second data feeds, Chainstack offers WebSocket subscriptions and, on Solana, the Yellowstone gRPC Geyser plugin. This plugin streams live transaction, account, block, and slot data directly from validator memory using a typed protobuf interface compatible with any language that supports gRPC. Jito ShredStream is enabled by default on Chainstack's Solana nodes, accelerating block data propagation and reducing tail latency.

AI and agent tooling. The platform publishes machine-readable llms.txt and pricing.md files and runs a Chainstack MCP Server that connects AI agents directly to blockchain infrastructure, positioning the service for agentic workflows that query on-chain data programmatically.

Multi-chain coverage. Supported protocols span major Layer 1s (Ethereum, Solana, Bitcoin, Avalanche), Ethereum Layer 2s (Arbitrum, Optimism, Base, zkSync Era, Starknet, World Chain), and emerging networks (TON, Hyperliquid, Sui, Aptos, XRP Ledger). New networks are added regularly; XRP Ledger and Stable Mainnet were added in August 2026.

Solana Ecosystem Fit

Solana is one of Chainstack's flagship supported networks. The platform provides standard JSON-RPC and WebSocket endpoints, full archive access, and the Yellowstone gRPC Geyser plugin as an add-on service priced from $49 per month for two concurrent streams. Jito ShredStream integration means Chainstack nodes receive block shreds at a stage closer to validator production, which is materially useful for MEV searchers, trading bots, and latency-sensitive applications. The platform's Unlimited Node tier removes per-request caps for teams with high Solana throughput requirements.

Tokens and Assets

Chainstack does not issue a native protocol token. It is an infrastructure-as-a-service business with subscription-based pricing. Top-up payments can be made via credit card or through more than 150 cryptocurrencies.

Team and Background

The company was co-founded in 2018 by Eugene Aseev, who brings a background in cybersecurity and R&D leadership, and Laurent Dedenis, who spent more than two decades in enterprise technology roles including positions at Microsoft Dynamics and Acumatica. Nils Hueneke took over as CEO, having previously led strategy at WebPros and served as Plesk CEO. The company is headquartered in Singapore, a jurisdiction that has been a hub for fintech and blockchain infrastructure businesses.

Chainstack does not disclose specific investor names or funding rounds in its public-facing materials.
