# Provider

Wepin Provider SDK for React Native. This package is exclusively available for use in React Native environments (Android and iOS).

Wepin supports providers that return JSON-RPC request responses to connect with blockchain networks. With Wepin Provider, you can easily connect to various networks supported by Wepin.

The providers supported by Wepin are as follows:

* [**Ethereum Provider**](https://eips.ethereum.org/EIPS/eip-1193): Used for interacting with EVM (Ethereum Virtual Machine) compatible networks such as Ethereum, Polygon, and Klaytn. It can be used for functions like calling smart contract methods, checking EVM-based token balances, and sending transactions.
* [**Kaia Provider**](/en/widget-integration/web-javascript-sdk/provider/kaia-provider.md): A provider that enables interaction with the Kaia blockchain. It supports JSON-RPC requests for account connection, transaction signing and broadcasting, and smart contract execution. Additionally, it is compatible with EVM-based blockchains for seamless integration.
