Chainstack is a blockchain node platform that powers global Web3 applications across fintech, DeFi, wallets, custodians, gaming, AI agents, trading, and analytics.
Chainstack's core products include Global Node, low-latency RPC endpoints for everyday workloads; Dedicated Node, single-tenant nodes with guaranteed resources for heavy workloads; reliable infrastructure built for trading bots and MEV strategies; and Unlimited Node, an add-on for unmetered request scaling. Together with Chainstack Self-Hosted for teams that need infrastructure on their own premises, these products cover every stage from prototyping to institutional-scale deployment.
Chainstack supports major blockchain networks, including Ethereum, Solana, BNB Chain, Polygon, Hyperliquid, Arc, Robinhood Chain, and other EVM-based and non-EVM chains, with elastic (auto-scaling) and dedicated node instances across mainnet and testnet. For Solana-focused trading and MEV operators, Chainstack offers the Yellowstone gRPC Geyser plugin for real-time on-chain data streaming and Jito ShredStream for low-latency transaction propagation.
Deployment options span the public cloud, preferred service providers, or fully self-hosted infrastructure, all managed through a single console with standardized node management across chains and environments. Core infrastructure features include global load-balanced RPC endpoints, blockchain data APIs, node monitoring, and request-unit-based usage tracking, keeping performance predictable and costs transparent as usage grows.
Chainstack offers a free Developer plan alongside paid Growth, Pro, Business, and Enterprise plans, so teams can start building at no cost and scale into preferred infrastructure setup as usage grows.
Teams cut time-to-market, cost, and risk with a single platform for blockchain nodes, whether in the cloud, through a preferred service provider, or self-hosted. Standardized node management across chains and environments puts reliability on autopilot and keeps performance predictable.
Operators get control and transparency, while developers get a consistent way to build and scale. Fintech companies, DeFi protocols, wallets, custodians, trading firms, analytics platforms, and Web3 service providers running fleets use Chainstack as the fastest way to run reliable, predictable blockchain nodes at scale.

Metis
To accelerate the transition of people to blockchain for open, fair, and decentralized business on Web 3.0. To create an easy-to-use technical and organizational platform, making blockchain accessible to everyone, empowering both personal and professional lives. Metis is a decentralized economy platform to start, run, and grow any decentralized app, business, and community on the blockchain with ease and scalability. We can integrate with your existing platform without you moving or changing any of your code. Depending on the smart contract stack involve, integration onto the Metis Layer 2 network will often take less than a day, thanks to our EVM equivalence. Metis kicks back 30% of the transaction revenue it collects every month to the DApps deployed on our Andromeda Layer 2 network. Optimistic has general EVM computation that Zk Rollups do not. In addition, zK Rollups currently create a “walled garden” effect, making it difficult for many developers to launch their DApps.
