​
Installation

Add the library to your project: 
yarn add @solana/web3.js

​
Polyfills

The following polyfills are needed, only if you intend to use the Keypair.generate function. Otherwise, this polyfill is not required to use @solana/web3.js.

​
Install getRandomValues

Add the react-native-get-random-values library to your project. 
yarn add react-native-get-random-values
Then, import the library in your app’s entrypoint file (e.g index.js), before the @solana/web3.js library is imported. 
import "react-native-get-random-values";
// ...other imports below
TIPAlternatively, you can use the expo-crypto library to polyfill crypto.getRandomValues. View this sample app for a reference of how to polyfill the crypto class.
