zkSync API Documentation with NOWNodes

The zkSync API gives developers, businesses, and blockchain projects secure access to the zkSync network through reliable zkSync RPC endpoints. As an EVM-compatible Layer 2 solution on Ethereum, zkSync allows you to use standard Ethereum RPC methods to read blockchain data, send transactions, and interact with smart contracts — but with lower fees and faster execution.

With NOWNodes zkSync RPC, you don’t need to run or maintain your own node. Our service provides stable full node and WebSocket access, ensuring real-time blockchain data, event subscriptions, and high-performance connectivity for production and testing environments.
