Metamask: What is the Polygon equivalent of `import { useWallet } from ‘@binance-chain/bsc-use-wallet’`

Here is an article about Metamask, the equivalent of import { useWallet } from '@binance-chain/bsc-use-wallet' for the Polygon network:

Introduction

Building a Binance Smart Chain (BSC) dapp that interacts with external wallets is crucial for user convenience. However, you may encounter issues when trying to migrate your existing project to the Polygon network due to compatibility issues or lack of support from popular wallet providers. In this article, we will explore the equivalent of import { useWallet } from '@binance-chain/bsc-use-wallet' in Polygon’s Metamask environment.

What is Polygon

Polygon is a layer-2 scaling solution for Ethereum that enables faster and cheaper transactions than the mainnet. It was launched as an alternative to Binance Smart Chain (BSC) and aims to provide more scalability and interoperability between Ethereum and other blockchain platforms.

Metamask and Polygon: Similarities and Differences

While Metamask is a popular wallet provider for both Ethereum and Polygon, the underlying architecture remains similar. To write equivalent code in Polygon’s Metamask environment, you need to understand a few key differences:

• Chain ID: The main difference between Ethereum (ETH) and BSC (Polygon) is their chain IDs. Ethereum has a chain ID of 0, while BSC uses a unique identifier for each network.

• Wallet Provider: While Metamask supports multiple wallets, including those compatible with Ethereum and Polygon, you may need to install and configure wallet providers specific to your desired chain.

• Contract ABI: The Accessible Binary Interface (ABI) defines the interface for external contracts. When interacting with a contract in Polygon’s Metamask environment, you will need to ensure that your wallet provider supports this ABI.

Equivalent Code

To demonstrate the equivalent code for import { useWallet } from '@binance-chain/bsc-use-wallet' in Polygon’s Metamask environment, consider the following example:

// Import the Binance Smart Chain (BSC) wallet provider
import { useWallet } from '@binance-chain/bsc-use-wallet';
// Create a new wallet provider instance with your preferred chain ID
const walletProvider = useWallet({
chainId: 0, // Ethereum chain ID
privateKey: 'YourPrivateKey', // Your private key (e.g. generated using the BSC metamask tool)
});
// Use the wallet provider to access your funds and interact with contracts on the mainnet
walletProvider.getBalance().then((balance) => {
console.log('Your balance:', balance);
});

Conclusion

In conclusion, while Metamask supports multiple wallets, including those compatible with Ethereum and Polygon, you will need to adapt your code to work with the specific chain ID, wallet provider, and contract ABI for your desired network. By understanding these differences, you can write equivalent code in Polygon’s Metamask environment and create seamless user experiences on both the mainnet and BSC.

Additional Tips

• Familiarize yourself with the Polygon blockchain explorer ( to learn about the available contracts and their interfaces.

• Experiment with different wallet providers, such as MetaMask or Chainlink, to find the best fit for your project’s requirements.

• Join the Polygon community and discussion forums to stay up to date on the latest developments, recommendations, and best practices.

By following these guidelines, you can successfully migrate your existing BSC dapp to the Polygon network using Metamask. Happy building!
