[Tutorial] How to link your Reddit Vault to your OpenSea account via Metamask

I've been seeing a number of posts on people asking how to sell their NFT avatars on OpenSea or link their Reddit vaults to their Metamask accounts. Hopefully, this guide will be simple enough for you guys to understand.

This tutorial is based off of u/v0rclaw's post. You can check it out here.

First and foremost, I suggest you do this using your mobile device since you can't really access your Reddit vault via desktop.

1. Click on your Profile picture (top right) on the Reddit mobile app then click on your 'Vault'.
2. At the top of your screen click on the three dots '...'
3. Click 'Show Recovery Phrase'
4. Copy your recovery phrase (there's usually a button that does this for you, or you could write it down manually if you want)
5. Download Metamask on your phone. Make sure to download it from your phone's official app store (App Store / Google Play Store).
6. Click through whatever welcoming messages it gives then click import from secret phrase. Note: afaik, you can't link your Reddit vault to an already-existing Metamask account.
7. Paste the words you copied earlier, and create a password for your Metamask.
8. Once you're in the Metamask account click at the very top of the screen where it says wallet, then click the blue add network button, then choose 'Polygon Mainnet' and confirm you want to add it.
9. Click the three lines in Metamask (in the upper left hand corner) and then click the button that says 'Browser'.
10. Go to OpenSea.io
11. Click the three lines in the left hand corner on Opensea.io then click the blue connect wallet button.
12. Choose Metamask from the list then approve the prompt that comes up.
13. Click the three lines again and navigate to where it says profile.
14. All your avatars will be listen here, click on the one you want to sell, press the 'Sell' button (this will not appear in the OpenSea mobile app), and then complete all the fields that brings up.

Additional Reminders:

1. You'll need some MATIC to cover the fees if you want to list some of your Reddit NFT avatars. The fees are very very low, so you don't need to put a lot.
2. If your avatar (usually one of the free ones i.e. Drip squad, Singularity, Meme Team, Aww Friends) doesn't appear in your OpenSea profile, go to 'hidden' as it is usually placed there.

​

Hope this helps!
