# MultiCall

A React + Redux library for fetching, batching, and caching chain state via the MultiCall contract.

## Setup

`yarn add @uniswap/redux-multicall` or `npm install @uniswap/redux-multicall`

## Usage

The usage of this library is similar to [RTK Query](https://redux-toolkit.js.org/rtk-query/overview#create-an-api-slice).

```js

// Somewhere in your app

export const multicall = createMulticall({ reducerPath: 'multicall' })

// In your store's root reducer

export const rootReducer = combineReducers({

  // Other reducers

  [multicall.reducerPath]: multicall.reducer

})

```

To use the updater, you'll need an instance of the Uniswap Multicall2 contract:

```js

import { abi as MulticallABI } from '@uniswap/v3-periphery/artifacts/contracts/lens/UniswapInterfaceMulticall.sol/UniswapInterfaceMulticall.json'

import { Contract } from '@ethersproject/contracts'

import { UniswapInterfaceMulticall } from './abi/types'

const multicall2Contract = new Contract(address, MulticallABI, provider) as UniswapInterfaceMulticall

```

For a more detailed example, see basic example app in `./integration-tests`

## Alpha software

The latest version of the SDK is used in production in the Uniswap Interface,

but it is considered Alpha software and may contain bugs or change significantly between patch versions.

If you have questions about how to use the SDK, please reach out in the `#dev-chat` channel of the Discord.
