Introduction

Binance Chain Extension Wallet is a Crypto Wallet for Binance Chain, Binance Smart Chain. You can send and receive funds on Binance Chain, Binance Smart Chain and cross-chain transfers between both of Binance’s blockchains. It’s currently supported in major browsers: Chrome and Firefox.

Since the latest release, Binance Chain Extension Wallet adds support for Ethereum blockchain and enable access for distributed applications, or "Dapps" in your browser!

If you don’t have Binance Chain extension installed in your browser, you can download the extension here.

Why you should use it

Secure your fund

Extension Wallet allows users to manage accounts and their keys in a variety of ways, while isolating them from the site context.

Back up your seed phrase!

The following point is enough to warrant its own subheading. Extension Wallet is a non-custodial service, meaning that no one else can access your funds – not even the developers. Your tokens exist in a sort of encrypted vault within your browser, protected by your password. That means that if your computer is lost, stolen, or destroyed, nobody can help you recover the wallet. Your private keys will be forever lost in the void of cyberspace.

So, it’s crucial that you write down your seed phrase. This is the only way you can restore your account should something unfortunate happen.

Where are my tokens?

So your BEP20 tokens gone, but your account doesn’t show your tokens. No need to panic – you have to add them manually.

For more popular tokens, you can select Add Token in your wallet and search for the name . In the future, you can also add the contract address to add the less popular ones

Cross-chain transfer

Binance Smart Chain is an innovative solution to bring programmability and interoperability to Binance Chain. Binance Smart Chain relies on a system of 21 validators with Proof of Staked Authority (PoSA) consensus that can support short block time and lower fees. Cross-chain transfer and other communication are possible due to native support of interoperability. This dual-chain architecture will be ideal for users to take advantage of the fast trading on one side and build their decentralized apps on the other side.

Cross-chain transfer with Extension Wallet is very sleek. You just need to type an address of different networks.

  • Auto-detect network type
  • Dual direction support
  • Automatic gas fee calculation

Staking BNB

A delegator can delegate its BNB to a chosen validator to participate in the consensus and earn rewards. Staking BNB directly contributes to the security of the entire network.

To understand the constraints of delegation operation, please read the following doc. To keep track of the current validators of Binance Smart Chain, you can go to this page:

dApp Development Guide

Since the latest release, Binance Chain Extension Wallet enables access for distributed applications or "Dapps" in your browser!

  • Blockchain Connection
    You can connect to the existing full nodes of Binance Smart Chain. For development, we recommend running in testnet first.
  • Binance Chain Provider API
    Binance Chain Wallet injects a global API into websites visited by its users at the window.BinanceChain.
    https://docs.binance.org/smart-chain/wallet/wallet_api.html
  • Basic Usage
    For any non-trivial Binance Smart Chain web application — a.k.a. web3 site — to work, you will have to:
  1. Detect the Binance Smart Chain provider (window.BinanceChain)
  2. Detect which Binance Smart Chain network the user is connected to. If Binance Chain is selected, you can fire a network switch request.
  3. Get the user's Binance Smart Chain account(s)
    You can learn how to accomplish the 2 and 3 from the above list by reviewing the snippet in the Using the Provider section

Downloads
