Follow these steps to use a Reveel Revenue Path in your OpenSea NFT collection:
1) Create your Revenue Path on the Reveel App
2) Copy the address of your Revenue Path smart contract
3) Navigate to the Creator Earnings settings on the collection where you'd like to use a Reveel Revenue Path
4) Set the royalty fee for secondary sales for your collection (up to 10%).
5) Paste your Reveel Revenue Path address into the “payout address” field
Once you have completed these steps, secondary transactions will be sent to the Reveel Path & distributed across all collaborators.
OpenSea provides instructions here.
As of right now, OpenSea lacks the ability to do this for individual NFTs.
