# JSON-RPC

For software applications to interact with the WEMIX3.0 blockchain, such as reading blockchain data or sending transactions to the network, they must connect to a WEMIX3.0 node. To do this, all WEMIX3.0 clients implement the JSON-RPC specification, providing a set of methods the application can use. JSON-RPC is a lightweight Remote Procedure Call(RPC) protocol without storing state. It is a transport method that can be used in multiple environments. It defines various data structures and processing rules and can be used within the same process, on sockets or HTTP, or in different message passing environments. Use JSON(RFC 4627) as the data format.

## WEMIX3.0 API Specifications

The WEMIX3.0 API specification is 100% compatible with the Ethereum API, and for more information, see the link to the Ethereum API specification.
