What is Polygon Network?

Polygon Network is a Layer 2 scaling solution designed to enhance the speed and reduce the cost of transactions on the Ethereum blockchain. It allows developers to build and connect Ethereum-compatible decentralized applications (dApps) with improved efficiency. Polygon (MATIC) is the native token used for governance, staking, and transaction fees within the network. Many users opt to interact with Polygon-based dApps and services, which often require the network to be manually added to wallets such as Coinbase Wallet.

Why Add Polygon Network to Coinbase Wallet?

Coinbase Wallet is a self-custodial wallet that gives users full control over their private keys and digital assets. While it supports many cryptocurrencies and tokens, Polygon (MATIC) and other tokens built on the Polygon network are not always automatically available. To send, receive, or interact with Polygon-based tokens, users must manually add the Polygon network to their wallet. This step ensures the wallet can communicate with the Polygon blockchain and display relevant balances and transaction data.

How to Access Coinbase Wallet Settings

Before adding the Polygon network, users must access the settings section of Coinbase Wallet. Open the app on your mobile device and locate the "Settings" icon, typically found in the bottom navigation bar or within the wallet management section. From the Settings menu, look for the option labeled "Networks" or "Blockchain Networks", which allows users to manage the blockchain networks connected to the wallet.

Steps to Add Polygon Network

To begin the process, ensure your Coinbase Wallet app is updated to the latest version. Navigate to the Networks section and select "Add Network" or "Custom Network" depending on the interface. You will need to manually input the following parameters:

• Network Name: Polygon Mainnet
• RPC URL: https://polygon-rpc.com/
• ChainID: 137
• Currency Symbol: MATIC
• Block Explorer URL: https://polygonscan.com/

Carefully enter each field to ensure compatibility and avoid transaction errors. Once all fields are filled in correctly, click "Save" or "Add" to finalize the configuration. The Polygon network should now appear in your list of available networks.

Verifying the Addition of Polygon Network

After completing the setup, return to the main wallet interface and check if you can now view Polygon (MATIC) or other tokens built on the Polygon blockchain. To test the integration, you can send a small amount of MATIC or a Polygon-based token to your wallet address. Ensure the transaction appears in your transaction history and that the balance updates accordingly. If the network is not functioning properly, revisit the Networks settings and double-check the entered details.

Sending and Receiving MATIC on Polygon

Once the Polygon Network is successfully added, users can send and receive MATIC tokens as well as other tokens built on Polygon, such as USDC on Polygon or QuickSwap (QUICK). To receive tokens, tap on the Receive button and select the Polygon Network from the list of available networks. This action will generate a wallet address specific to the Polygon blockchain. When sending tokens, ensure the recipient's address is compatible with the Polygon network to avoid irreversible loss of funds.

Interacting with Polygon-Based dApps

With the Polygon Network added to Coinbase Wallet, users can now interact with decentralized applications built on Polygon. This includes platforms like QuickSwap, Aave, and Polygon Studios. To connect your wallet, open the dApp in your browser or mobile app, click "Connect Wallet", and choose Coinbase Wallet from the available options. Follow the prompts to authorize the connection and begin interacting with the dApp using your Polygon wallet.

Frequently Asked Questions

Q: Can I add Polygon testnet to Coinbase Wallet?

Yes, you can add the Polygon testnet by entering the appropriate testnet RPC URL and chain ID. However, testnet tokens have no real-world value and are used solely for development and testing purposes.

Q: What should I do if my MATIC balance doesn't show up after adding the network?

Ensure you are viewing the correct network in your wallet and that the tokens were sent to the correct address. You can also try importing the wallet into a different wallet service like MetaMask to verify.

Q: Is it safe to add custom networks to Coinbase Wallet?

Adding custom networks is generally safe if you use trusted RPC URLs and chain IDs. Always verify the parameters from official sources to avoid potential risks like network spoofing.

Q: Can I remove the Polygon network from Coinbase Wallet?

Yes, you can remove the network by going to the Networks section in settings and selecting "Delete" or "Remove" next to the Polygon network. Note that this will not delete your wallet address or private keys.
