hiIQ NFT Raffles

[zer0blockchain]

Solving

• multichain hiIQ holders
• passive way for hiIQ holders to participate
• gas efficient way to run NFT raffles

Proposed Solution

• multichain snapshot of hiIQ holders at a predefined block
• all hiIQ holders will be entered into the raffle proportional to their hiIQ holdings at the time of snapshot
• this allows hiIQ holders a way to passively hold and participate
• minimal gas cost for holding a Raffle and scales well
• snapshot stored on IPFS and hash pushed onchain as part of raffle (is this possible to push a ZKP onchain?)
• raffle drawing will use randomness from PRNG or chainlink to resolve the raffle
• winner will receive the NFT

Onchain info

• IPFS hash of all hiIQ holders and their raffle ticket numbers
• IPFS snapshot block number
• Raffle start datetime
• Raffle end datetime
• resolution (could have multiple winners?)
• prize contract (ERC721 contract addr and tokenID)

I would suggest to add a onERC721Received interface that will be use to add NFTs to the raffle

you can get as inspiration what aavegotchi does for handle erc1155 and decode the raffleID from data
