Update Contracts to use latest dependencies

[joelamouche]

Hi Polygon Decs, congratulations on the new release!

Would it be possible to update contracts repo with the latest versions?

StateV2 doesn't exist in latest version of @iden3/contracts for https://github.com/0xPolygonID/contracts/blob/main/contracts/validators/CredentialAtomicQuerySigValidator.sol

Thanks in advance!

This release 1.1.0 is a tag for production legacy contracts. All further changes will be committed to the main branch and a major version of the example will be released. All fixes to production example contracts (validators) will be made to this tag.

fixed lock file on main branch. You can use main version as example.

latest version 1.3.0 doesn’t contain Statev2, but it’s predicted and we are working on update.

or you can stick to version of 1.1.0 in your branch in case you use have own project.

I was able to to do most of the contract updates by replacing by Statev2 with State, etc.
I also had to manually add int256ToAddress that was removed from GenesisUtils.
But now my main problem is how to build the data for the setRequest call.
I have the values for the previous call:

bool res = setZKPRequest(
      requestId,
      validator,
      schema,
      claimPathKey,
      operator,
      value
    );

but not for the new call:
setZKPRequest(requestId, request);

https://github.com/iden3/contracts/blob/master/contracts/verifiers/ZKPVerifier.sol

with request being:

struct ZKPRequest {
string metadata;
ICircuitValidator validator;
bytes data;
}

Awesome! Looking forward to it. I will take a look if I get the opportunity

Hi @vmidyllic
Finally got around to implement this in our code base. Thank you for the work it was very helpful.

BTW I had to rewrite this function to use viem instead of web3 (might be useful to you or other users):

export function packValidatorParams(
  query: OnChainQueryRequest,
  allowedIssuers = [],
) {
  return encodeAbiParameters(
    [
      {
        name: "CredentialAtomicQuery",
        type: "tuple",
        components: [
          { name: "schema", type: "uint256" },
          { name: "claimPathKey", type: "uint256" },
          { name: "operator", type: "uint256" },
          { name: "slotIndex", type: "uint256" },
          { name: "value", type: "uint256[]" },
          { name: "queryHash", type: "uint256" },
          { name: "allowedIssuers", type: "uint256[]" },
          { name: "circuitIds", type: "string[]" },
          { name: "skipClaimRevocationCheck", type: "bool" },
          { name: "claimPathNotExists", type: "uint256" },
        ],
      },
    ],
    [
      {
        schema: BigInt(query.schema),
        claimPathKey: BigInt(query.claimPathKey),
        operator: BigInt(query.operator),
        slotIndex: BigInt(query.slotIndex),
        value: query.value.map((v) => BigInt(v)),
        queryHash: BigInt(query.queryHash),
        allowedIssuers: allowedIssuers,
        circuitIds: query.circuitIds,
        skipClaimRevocationCheck: query.skipClaimRevocationCheck,
        claimPathNotExists: BigInt(query.claimPathNotExists),
      },
    ],
  );
}

Also, I think verifier address in https://github.com/0xPolygonID/tutorial-examples/blob/main/on-chain-verification/scripts/deployValidators.js doesn’t seem to be correct. I had to deploy my own VerifierSigWrapper/VerifierSig for it to work
