+title: Using the Sui Wallet Browser Extension
+---
+
+Welcome to the [Sui Wallet Browser Chrome Extension](https://chrome.google.com/webstore/detail/sui-wallet/albddfdbohgeonpapellnjadnddglhgn?hl=en&authuser=0) covering its installation and use. The Sui Wallet Browser Extension acts as your portal to the Web3 world.
+
+## Features
+
+The Sui Wallet Browser Extension offers these features:
+
+* Create, import, and persistently store the mnemonics and the derived private key
+* Transfer coins
+* See owned fungible tokens and NFTs
+* Display recent transactions
+* Go directly to the successful/failed transaction in the Sui Explorer
+
+Note, the wallet will auto split/merge coins if the address does not have a Coin object with the exact transfer amount. See the [Use](#use) section for guidance on employing these features.
+
+## Purpose
+
+Initially, the Sui Wallet Browser Extension is aimed at Sui developers for testing purposes. As such, the tokens are of no value (just like the rest of [DevNet](https://github.com/MystenLabs/sui/blob/main/doc/src/explore/devnet.md)) and will disappear each time we reset the network. In time, the Sui Wallet Browser Extension will be production ready for real tokens.
+
+This browser extension is a pared-down version of the [Sui Wallet command line interface (CLI)](https://github.com/MystenLabs/sui/blob/main/doc/src/build/wallet.md) that provides greater ease of use for the most commonly used features. If you need more advanced features, such as merge/split coins or make arbitrary [Move](https://github.com/MystenLabs/sui/blob/main/doc/src/build/move.md) calls, instead use the [Wallet CLI](https://github.com/MystenLabs/sui/blob/main/doc/src/build/wallet.md).
+
