Ethereum JSON-RPC

The JSON-PRC Server provides an API that allows you to connect to the Neura blockchain and interact with the EVM. This gives you direct access to reading Ethereum-formatted transactions or sending them to the network which otherwise wouldn't be possible on a Cosmos chain, such as Neura.

JSON-RPC is a stateless, light-weight remote procedure call (RPC) protocol. It defines several data structures and the rules around their processing. JSON-RPC is provided on multiple transports. Neura supports JSON-RPC over HTTP and WebSocket. Transports must be enabled through command-line flags or through the `app.toml` configuration file. It uses JSON (RFC 4627) as data format.

JSON-RPC over HTTP

Neura supports most of the standard web3 JSON-RPC APIs to connect with existing Ethereum-compatible web3 tooling over HTTP. Ethereum JSON-RPC APIs use a namespace system. RPC methods are grouped into several categories depending on their purpose. All method names are composed of the namespace, an underscore, and the actual method name within the namespace. For example, the eth_call method resides in the eth namespace. Access to RPC methods can be enabled on a per-namespace basis.

Find below the JSON-RPC namespaces supported on Neura or head over to the documentation for the individual API endpoints and their respective curl commands on the JSON-RPC Methods page.

Namespace	Description	Supported	Enabled by Default
eth	Neura 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 node instance, including but not limited to network peer and RPC endpoint management.	🚫
personal	The personal API manages private keys in the key store.	✔	🚫
