Mission: Get the images

from: https://opensea.io/collection/etherean-empire-drops

Strategy:

1. Get All elements from this uri , address and tokenID from 0 to 10
2. scrapp details > tokenID
3. getJSON , insert it into a new metadata object
4. parse image cid (IPFS)
5. from the cid get the image
6. download it to ./assets/

format: uri/address/tokenId [0,10]

Mission: Deploy image and meta

Strategy:

1. Redeploy the images secuencially to ipfs or pinata , [research] ipfs.js and pineIT how to deploy NFTs from opensea
2. Redeploy metadata using the new CID by tokenId

/*  
    i.e:
    meta.image = "ipfs://foobarbazthingsdjfjkh"
*/

{
    "name": "foo",
    "description": "bar", 
    "external_url": "ask to rallsen", 
    "image": "${meta.image}",
    "attributes": 
        [
        {
            "trait_type": "Rarity",
            "value": "Legendary"
        }
    ]
}

Mission: Map the entire transaction tree

Strategy:

• research
  • Research merkel trees
  • Research solutions:

    • query the event log

    • scraping on OpenSea

    • research NFTs APIs https://ethereum.stackexchange.com/questions/107526/how-can-i-query-to-find-all-nft-token-holders https://ethereum.stackexchange.com/questions/36274/a-list-of-token-holders-at-a-specific-time/64814#64814 https://github.com/TokenMarketNet/sto/blob/master/sto/ethereum/scanner.py

      • the openSea API

      • Alchemy

      • Moralis

  • Research on 1155, holders

1. Get map the owner list and their transactions into a merkle tree

Mission: Mint on demand

Strategy:

1. create-next-app
2. create a frontend
3. create an API
   • use firebase as DB
4. Integrate frontend and backend with the API

• tasks
  • import material
  • walletConnect
    • validate ownership
  • API
    • GET api/wallet/[:address] - Verify the tree?
    • GET api/id/[:id]/owners - returns a ownerList by Address
    • GET api/wallet/[:address]/[:tokenID] - returns metadata
    • Por ahora no mucho mas los minteos se manejan desde el abi

. Deploy the new 1155 contract with (entrypoint tokenId) on testnet
