RPC Endpoints

CDK-Erigon provides json-rpc API endpoints for interacting with RPC nodes. These APIs are divided into namespaces:

Ethereum JSON-RPC API​

The standard Ethereum JSON-RPC API methods allow applications to interact with the blockchain in the same way they would with any Ethereum-compatible network.

zkEVM JSON-RPC API​

The zkEVM-specific json-rpc API provides methods unique to the Polygon zkEVM implementation, including batch management, verification status, and other zkEVM-specific functionality.

Security Recommendations​

When exposing RPC endpoints, consider these security best practices:

  1. Use TLS/SSL for all public-facing endpoints
  2. Implement authentication mechanisms (API keys or JWT tokens)
  3. Configure firewalls to restrict access to trusted IPs
  4. Limit exposed API methods to only what is necessary
