Claims

How to prepare a claim

Generating JSON file with every asset and associated data

You have to use (or create) a script using the graph or other data source depending on the context, to create a JSON file containing asset IDs and amounts.

JSON format:

[
  {
    "to": "0x9E7A5b836Da4d55D681Eed4495370e96295c785f", // recipient of the assets
    "erc1155": [
      {
        "ids": [
          // array of asset id
          "106914169990095390281037231343508379541260342522117732053367995686304065005572",
          "106914169990095390281037231343508379541260342522117732053367995686304065005568"
        ],
        "values": [
          // array of amount for each asset id
          1,
          1
        ],
        "contractAddress": "0xa342f5D851E866E18ff98F351f2c6637f4478dB5" // address of asset contract (most of the time our contract 0xa342f5D851E866E18ff98F351f2c6637f4478dB5)
      }
    ],
    "erc721": [], // empty
    "erc20": {
      // empty
      "amounts": [],
      "contractAddresses": []
    }
  }
]

Save your script (if you had to create one) in the repos and add the link to it in the first paragraph of the Claims Template file. Save also your JSON file in the data/<network>/<claim_name>_salt folder.

Note:

• we use the strictly unique incremental ID for salt.
• to should be unique in the same json.

Execute script to gen merkle root and proofs

Generate merkle root and proofs

yarn gen <network> <claim_name> <salt>

example:

yarn gen mumbai test 1

After the script execution, proof locate at data/<network>/proof/<claim_name>_salt and merkle root locate at data/<network>/root/<claim_name>_salt

Add merkle root to claims contract

Verify the proof to ensure the root is right
