Here at Ankr we make node infrastructure that is easy, accessible, affordable and instantly distributed across the globe.

Currently, we have three different lines of business: Staking Nodes - One-click solutions for staking nodes with rewards earning possibilities. Developer APIs - Easily build Web3 products with instant API access to major blockchain and DeFi protocols. Enterprise Solutions - Turnkey infrastructure solutions for cryptocurrency exchanges, staking platforms, data analytics providers and more. These docs will focus on the Ankr API’s that align with what Covalent offers. Full documentation here.

Binance Smart Chain

Binance Smart Chain brings EVM-compatible smart contract functionality to Binance Chain. Thanks to a dual-chain architecture with cross-chain communication, users can create dApps and tokens on the Smart Chain and leverage Binance Chain for fast trading on Binance DEX.

Launched in 2015, Ethereum is an open-source, blockchain-based, decentralized software platform used for its own cryptocurrency, ether. It enables SmartContracts and Distributed Applications (ĐApps) to be built and run without any downtime, fraud, control, or interference from a third party The official RPC API description can be found here.



Polkadot enables cross-blockchain transfers of any type of data or asset, not just tokens. Connecting to Polkadot gives you the ability to interoperate with a wide variety of blockchains in the Polkadot network. There are a lot of parachains that share the same underlying technology as Polkadot, and that leads to the fact that they will share the same RPC-API calls. The official RPC-API documentation can be found here.



The Matic Network is a blockchain scalability platform which provides secure, scalable and instant transactions powered by PoS side chains and an adapted version of Plasma with PoS based side chains.
