Opensea is one of the most popular and lively NFT marketplaces around at the moment and a great place to start if you’re looking to get into NFTs. However, before you start buying, selling and minting your own NFTs, you will need a cryptocurrency wallet. 

One popular choice is MetaMask, an Ethereum wallet that installs itself as a browser extension on Chrome or Chromium-based browsers such as Edge and works in just a single click.

However, that user experience can be spoiled by bugs and glitches. So if you’re experiencing problems connecting MetaMask to Opensea, here are a few solutions you can try out. 

Try another browser

MetaMask works best as an extension, and it is designed for Chrome (or Chromium-based browsers). If you’re experiencing this issue on any browser other than Chrome, try switching to Chrome and see if that solves the ‘Can’t connect Metamask to Opensea’ issue.

Reinstall the extension

If switching the browser doesn’t work, head over to chrome://extensions and remove the MetaMask extension. Once done, you can head over to the Chrome App Store and download and install the extension again. Make sure to have your password and secret phase handy; otherwise, you will lose access to your account and any assets or ETH within. 

Disable browser extensions 

Head over to chrome://extensions and try disabling all your extensions to check if the browser starts functioning again. If it does, enable them one by one until you have the MetaMask extension working correctly again.
