Claim Page allows you to reward your collectors with a free mint using your existing Manifold Creator contract. Claim Page supports both ERC-721 and ERC-1155 NFTs and can be configured with an Allow List.
Be aware that all tokens claimed will be minted under the same contract so it's up to you to decide if you want them to be in a new collection or in the current collection where you might be minting your other tokens.
Using an Allow List
Claim Page allows you to specify the wallets that can claim your tokens through a CSV file.
The format of the CSV file needs to include the following fields:
address: the wallet addresses that are allowed to claim (ENS addresses are not supported)
value: a value indicating how many tokens can each wallet claim. A value of 0 will mean that the wallet has not limit to the number of tokens they can claim.
