Essential For DeFi
If you are utilizing the wonderful world of DeFi, then you are probably quite familiar with MetaMask, a browser extension. MetaMask is a non-custodial wallet that can be used to authorize and sign transactions on DeFi platforms and smart contracts. The great thing about MetaMask is that you can add multiple chains and, therefore, simply switch between wallets when operating on different chains.
This is why I use MetaMask, as it simplifies operations. For instance, when using Solana-based DeFi protocols, you need a wallet like Sollet.io. There is no SOL support in MetaMask yet, so you need another extension to use SOL-based protocols. This would be the case for many chains if MetaMask were not compatible with multiple chains. Solana has since been added and is available in 2026.
A lot of BSC users will be looking to add Polygon, as CubFinance is about to launch an airdrop for users who are staking CUB in their Kingdoms vault. The airdrop will last 60 days and looks to be extremely rewarding for CUB holders.
Creating Your Own Polygon Metamask Wallet
If you do not already have a MetaMask wallet, you can download the extension from the official MetaMask website. You can import an existing wallet or create a new one. Once your wallet is installed, simply click the “Networks” button. This is displayed below, where the current network is displayed as BSC.
Then scroll to the bottom of the window and select “Custom RPC,” as shown in the screenshot below.
After selecting “Custom RPC”, you will see a window like the one in the screenshot below.
What you need to do now is to enter the following information in the appropriate spaces.
- Network Name – Polygon
- New RPC URL – https://polygon-rpc.com
- ChainID – 137
- Symbol – MATIC
- Block Explorer URL – https://polygonscan.com/
Once you have entered and checked your information, simply click save! I always advise sending some POL/MATIC over to your wallet just to test that everything is working correctly. The transaction fee is extremely low, so it makes sense to ensure everything is perfect.
