You could burn them. Or you could simply blank out the metadata and kill the tokens that way, and deploy a new contract.
If you’re intending to sell these on manifold, the recommended way would be to sell them all and do a post sale reveal so it’s not predictable which token someone would get.
So, to avoid confusion, if you intend to sell 1315 tokens of a collection on manifold, you should:
- Create a new claim page (ERC721)
- Set a limit of 1315
- Set the assets and description to indicate that all tokens are unique and the tokens people get won’t be revealed until sale ends. (Important to make the mint random)
Once it’s done, you do a post mint reveal. See:
For the existing tokens, you should remove the assets and disable the claim page (set the token metadata to blank or some placeholder). You could burn them all but there doesn’t seem to be a point to doing so.
