Overview - ZKsync Docs

This page provides you with a high-level overview of our API capabilities and essential information.

ZKsync seamlessly integrates with the Ethereum ecosystem. To achieve this integration, we support not only the standard Ethereum JSON-RPC API but also introduce L2-specific features that enhance functionality.

ZKsync supports RPC providers that comply with the official Ethereum JSON-RPC API specification. You can explore a comprehensive list of supported RPC providers in our RPC ecosystem page.

To ensure a seamless experience, we impose rate limits on both HTTPS and WebSocket APIs. Generally, these limits are ample, ranging from 10 to 100 requests per second (RPS) per client.
