Ability to mint NFT in someone's collections

[vikiival]

Preface

We plan to make a trustless migration of RMRKv1 NFTs into the Basilisk and we observed a technical limitation.

• kodadot/grants#5

Let's make following scenario:

• Viki (artist) has collection of 2 NFTs (1st is his, second is owned by Wao)
• V migrates collection and his NFT to the Basilisk (meaning: create(collection), mint(nft), burn(rmrk))
• However W has still has his NFT on RMRK.
• How can W get his NFT without having "two" copies both on RMRK and BSX?

Possible solutions

1. Create Proxy that would allow only minting

Currently proxy does not have permissions to set only minting, via proxy W could mint his NFT in V's collection and burn his without harm.

2. Extend NFT pallet to whitelist (PC: allowlist) W to mint n NFTs

Other possible case is to have two new functions in the NFT pallet:

• allow_mint(id: CollectionId, who: AccountId, count: u32)
• mint_as_allowed(params_are_same_as_for_mint)

We would like to proceed with this functionality so let us know here or via privately via Discord.

1 Proxy

• Specify which
  • collection address can be minting in
  • the item can be minted

To avoid address, can mint artificially other nfts which aren't in collections or items they don't own on RMRK

Any updates on this? Heard some fix might go out this week?
