Hello, would gladly know your opinion on this.
- ERC721 collectible, 10000 pcs
- some have rare properties, clearly visible on images
- minting should go from 1 - 10000 in order
- all revealed after sell-out
I have couple of ideas how to pull this of:
Effortless way seems to be provide randomized metadata, put it to ipfs and provide provenance hash. I don't like that operators would know sequence of rare items though. Or do you see any other problem with it? I have been told that lot of collectibles projects just go with it, but my inner alarm is going red.
Using chainlink VRF for selecting rare items after sell-out, uploading fresh metadata and then reveal. Calling VRF one time, I presume, I like it, except that total replacement of ipfs CID. But it's cheaper than number 3.
Using chainlink VRF with probability function to generate rare/non-rare item, and keep watch on count of these. Personally don't like this one because of gas money for calling VRF every time user mints.
This I didn't go through yet, but it's existing contract and it is using VRF. I will se about that. LobsterDAO
What's your take on this, may I ask? Thanks.
