Search all tip4 collections of the network

The IndexBasis contract is used to search for all Collection contracts. Because the code of the Collection contracts may differ - it is impossible to find all tip 4 collections on the network. To simplify the search, an Index Basic contract was invented, issued by a Collection contract whose code is the one. With this, we can find all the IndexBasis contracts, which in turn will store the addresses of the Collection contracts.

Get the codeHash of the IndexBasis contract using the NFTIndexHelper contract:

tonos-cli run 0:e7982fb2c60892956dd04f90e118db98ddda146c05742aa369466d2029c042e6 indexBasisCodeHash '{"answerId": 0}' --abi NFTIndexHelper.abi.json

}

Using codeHash of the IndexBasis contract we can make a query in graphql:

query { 
    accounts 
    (filter : {
        code_hash :{eq : "51d2e5e5718525436e8179cd5450038c2f1dcf6e4fd8a2c1526d114aad0e0f84"}
    })
{
    id
}}

Where "51d2e5e5718525436e8179cd5450038c2f1dcf6e4fd8a2c1526d114aad0e0f84" - codehash of the IndexBasis contract

{

    "accounts": [
      {
        "id": "0:00a70f22964025297d9f3130fe00c5c25c827db5b72dff44179a29430c45858d"
      },
      {

      }
    ]
  }
}

Knowing the abi of the IndexBasis contract, we will call its get method getInfo:

tonos-cli run 0:00a70f22964025297d9f3130fe00c5c25c827db5b72dff44179a29430c45858d getInfo '{"answerId": 0}' --abi IndexBasis.abi.json
Input arguments:

  method: getInfo
  params: {"answerId": 0}
     abi: IndexBasis.abi.json
    ...

}

As a result, we get the address of the Collection contract.

Search for all NFTs by owner and collection address

Calling the indexCodeHash method of the NFTIndexHelper contract, passing the address of the collection and the address of the owner

• passing collection address 0:89fc1823620306035d6b2fb91e819649d3e7c3c894dea967c1ee7d7d6d9e365c
• passing owner address 0:5eb79f5d5aa10fa4d80067b370984c9bc686f61a7810060a46353ea2c47527bd

We get:

}

We received Index code_hash (Method calculated the code_hash based on TvmCell code + collection address)

We get all index contracts related to this collection and the owner:

query { accounts (filter : {
    code_hash :{eq : "993a53200c7aae1b340b6bb4d523e5868785fdd45849cf18353103d7b56906c0"}

      }
    ]
  }
}

Then, calling the getInfo method for each index, we get the address of the nft

Input arguments:

Get all collection nfts

Knowing the address of the collection contract, we can call nftCodeHash method to get the nftCodeHash:

abi.json file can be taken in the "./abi" directory

tonos-cli --url "eri01.main.everos.dev" run 0:999fa9e3331291a2fc2291a5663ef893733c838a3f4d0c5411378f4724f626d2 nftCodeHash '{"answerId": 0}' --abi TIP4_1Collection.abi.json

Get all the nft contracts of the collection:
