integrate NFTs

[tac0turtle]

Fund receipts are generalized SPL tokens. We would like to have a nft to track redemption.

the SPL token contract can be treated as an NFT if you disable minting: https://spl.solana.com/token#example-create-a-non-fungible-token.

one way to do grouping here is on a deposit you mint a token(s) representing the deposit. You set mint authority to none after this initial mint. After the creation is done the fund has an array of pubkeys representing the minted nfts.

mint 100 tokens -> disable mint -> add token account to fund as a struct

Question here is how to do redemption?

Option 1

• There could be a client that watches the fund and handles work off chain.

Option 2

• track token holders in the contract
  • this prevents secondary markets but could be a tradeoff for now

I am leaning towards option 2 for the initial version. Later on we can work on moving to NFT's that enable secondary markets with the shares
