Node API
Ankr provides a fast, reliable, and distributed network of blockchain nodes and staking solutions to power Web3 projects.
Overview
Ankr is a comprehensive Web3 infrastructure platform that offers a globally distributed network of blockchain nodes, enabling developers to build fast and reliable decentralized applications (dapps). It supports over 70 blockchains with an average response time of 56 milliseconds and 99.99% uptime, making it a leading RPC (Remote Procedure Call) node provider. Ankr’s decentralized physical infrastructure network (DePIN) spans 30+ global regions and serves 760,000 unique geo locations monthly, ensuring low-latency access to blockchain data worldwide. This infrastructure is designed to power Web3 projects with scalable, high-performance connectivity.
Beyond node services, Ankr provides rollup and sidechain creation as a service, allowing teams to launch dedicated Layer 2 solutions with end-to-end engineering support. Its staking solutions enable seamless integration of liquid staking across multiple chains and tokens, with over $83 million in total value locked (TVL) and 18,000+ users earning rewards securely. Ankr’s staking APIs and dashboards facilitate easy embedding of staking features into dapps, supporting assets like Ethereum, Polygon, Avalanche, and Binance Smart Chain.
Ankr differentiates itself through its extensive multi-chain support, decentralized node infrastructure that reduces latency globally, and combined offerings of RPC services, staking, and rollup creation. It powers major ecosystems such as Polygon, BNB Chain, and Mantle, delivering up to 10x faster app performance and handling billions of daily RPC requests. Developers can get started quickly with free RPC endpoints, comprehensive documentation, and SDKs. Enterprise clients can also access tailored infrastructure and engineering services to meet specific scalability and customization needs.
