Steps what we do for listing collection.


  1. Get particular NFT tokenId. If collection if ERC721Enumerable - tokenByIndex. Other case no need, id iteration will be 0,1,2.

  2. Get token metadata - tokenURI by id. 

  3. From metadata get image, gif etc, and store in s3 bucket with specific naming( paramCase lib). 
5. Store rest of data into DB, token (info, metadata, attributes) without duplicates. 

Key thing in todo it fast, because some collection has 10 000 items.
  4. Store banner, avatar.
