API Overview

Info

The API exposed by the EN is designed to be Web3-compliant. Any deviation from the Ethereum behavior is likely unintended, and we encourage users to report such discrepancies.

en Namespace

This namespace includes methods that external nodes call on the main node during syncing. If this namespace is active, other ENs can sync using this node.
