How to configure Metamask wallet to buy Polygon NFTs on Open Sea

Hello my friends. Today I am going to show you how to use metamask to create your Open Sea account and buy polygons NFTS.



First thing you need to do is download metamask for internet browser or for mobile. When downloaded it is going to ask you if you are new, if yes you would proceed to create a new wallet and to create a password. When done it will show you your secret recovery phrase. It is basically a set of random words used to identify and recover your wallet. You can download this word, print them and store in a special place to never forget this as you can not restore your wallet without this phrase.


Once downloaded and created your wallet, you would need to click on the right border where it says "Ethereum mainnet". In the last option it will say "Personalized RPC". Click that and you would need to copy the Polygon information:



Network Name: Polygon

New RPC URL: https://polygon-rpc.com or

https://rpc-mainnet.matic.network or

https://rpc-mainnet.maticvigil.com or

https://rpc-mainnet.matic.quiknode.pro

ChainID: 137

Symbol: MATIC

Block Explorer URL: https://polygonscan.com/


Finally click save.

Now that the Polygon mainnet is set. You will only need to add WETH token to be shown on metamask. In the main menu click the below button "Add token". And just copy the "Token Contract Address" that is: 0x7ceb23fd6bc0add59e62ac25578270cff1b9f619 the rest of the info will be auto completed.


That is all for metamask. The only thing you need to do for creating Opensea account is going to its website. In the right upper corner it will show a wallet icon, click on that and just click the metamask option. And just sign the messages. When done, you will only have to configure your profile name, picture and email.



That will be all, you are ready to buy some Paletos NFT. remember to fund your metamask using the Polygon blockchain.
