Pre-requisite Readings

Ethereum Namespaces

Namespace
Description
Supported
Enabled by Default
eth
Cronos provides several extensions to the standard eth JSON-RPC namespace.
web3
The web3 API provides utility functions for the web3 client.
net
The net API provides access to network information of the node
clique
The clique API provides access to the state of the clique consensus engine. You can use this API to manage signer votes and to check the health of a private network.
debug
The debug API gives you access to several non-standard RPC methods, which will allow you to inspect, debug and set certain debugging flags during runtime.
les
The les API allows you to manage LES server settings, including client parameters and payment settings for prioritized clients. It also provides functions to query checkpoint information in both server and client mode.
miner
The miner API allows you to remote control the node’s mining operation and set various mining specific settings.
txpool
The txpool API gives you access to several non-standard RPC methods to inspect the contents of the transaction pool containing all the currently pending transactions as well as the ones queued for future processing.
admin
The admin API gives you access to several non-standard RPC methods, which will allow you to have a fine grained control over your nodeinstance, including but not limited to network peer and RPC endpoint management.
personal
The personal API manages private keys in the key store.
