Our project has some success with NFTs (Ethereum). We have ERC721a NFTs that were minted, they generate ERC20 currency tokens, this combines to breed an ERC1155 item. If you don't answer the questions I don't accept your proposal. Next, the ERC115 and ERC20 combine to form another ERC721a family member. Finally we have multiple other scenarios combining above to form even more special characters. There are multiple collections and various transactions in this ecosystem, some community members do them right away at the same time if they have enough assets. Some of the traits on-chain metadata gets updated too. 1. Which of the above token types are you most and least familiar with, or are you good at problem-solving to figuring out any of them? 2. How can we combine some of the transactions into just a single transaction? Any creative solutions would be good how you would approach it. 3. We are thinking of unique ideas of what is possible in the above scenarios. What are your ideas if anything above can be combined in any other way? We're exploring certain scenarios if they are impossible to modify traits/items, on or off chain? For example, if NFT gets stolen... can we still use it, modify it, or re-create it... Curious how you think. 4. For any specific feature above (#2 or #3), how long would it take you to build a quick MVP for testing/feasibility and then how long it would take to make it ideal? We have a 2nd big collection coming up but first curious to build multiple smaller features with our existing agile team, but you being the main web3 dev. For question #2 above, please provide details for your strategy or workflow, or for me to easily tell you know what you're talking about rather than just saying "it's possible". Looking forward to chatting!

1. I am familair with ERC 1155, 721, and 20. I think you need to make breed contract for your idea. 2. If I understand what you want correctly, it's impossible. I'd like to make sure what you want exactly. 3. I can make mechanism to pause stolen nft. 4. I can make any contract in 2 days. But I need to make sure what you want before starting work.

Hi. Thanks for your post. As a senior blockchain developer, I worked in erc20, erc721, DEFI, DAO, NFT marketplace, etc. I am very interesting in your post. I will answer your questions. 1. I am very familiar in erc20 especially, and also have rich experience in erc721 but have done no work with erc1155. 2. I think, it is good to make new smart contract which handle multi transactions. It is making users more friendly and saves gas fee too. 3. Blockchain is famous for immutability. I don't think it is a good idea to modify NFT or re-create it. But I think we can make it more secure by using multi sign mechanism. 4. I am not sure now because I need to know more detail about your project and workflow. Please contact me and discuss more. I am waiting your response. Thanks.

1. Most familiar: ERC20, ERC721A Least familiar: ERC1155 (I don't participate much in game nft projects) 2. I think proof pattern will solve this problem (provided that users' token is deposited in a vault) - With erc20, i need to create proof of balance for all users - With erc721, i need to create proof of proof of ownership for all users Ofcourse, when depositing and withdrawing from the vault, the user will have to provide proof that matches the root one (this can be generated from offchain) 3. You can refer to rentable nft 4. about 2 man-weeks

Fortunately, I worked on such a design a few months ago. 1. all the same, but I made another standard called ERC721Y, which is more optimized than ERC721a. My version consumes ~25000 gas units for free mints and ~36000 units for regular whitelisted mints 2. I Can't go into details here, but it gets done through a proxy contract to distribute the different scenarios into different functions; in this way, we can have an optimized solution for every combination. 3. You can read 2 one more time, and in addition to stolen NFTs, I think it's not a good idea to alter metadata whether its on-chain or off-chain(changing the baseURI) 4. it depends on many more details, but it might take up to ~12 working days, maybe sooner. And the end product might take two weeks (including testings and optimizations and ...) Question for you: Are you looking for a core member? I'm available. Let's discuss it in detail.
