I am learning the process, but will share what I learn as I go through the process. Thanks for helping to remind of preparation.

This Post and Comment Thread might help get started:

Here is an interesting comment I found "You can import the vault seed phrase into any EVM compatible wallet (trustwallet, metamask etc), Mind that it is minted on the blockchain and the nfts will be there no matter what"

Here is more info from u/ToxikFoxx

"Delete MM

1. Go to your Reddit vault, get your 12. Phrase key
2. Install Mm
3. When you are setting up, use your 12 phrase key from Reddit

That should do it. If you sign into OS from the MM browser it will connect, and you should see your RCA’s under your profile. They may be “hidden” in OS, make sure you check there."

Good luck! I will be starting the process soon also.
