Badges: Custom gating for your App

It's easy to create custom badges on top of Sismo attestations!
For example: an ERC721 Badge built on top of two attestations certifying membership in the 'ENS DAO voters' groups:
one issued by a Public Attester
one issued by a ZK attestation
A user can receive this Badge if and only if they demonstrated to be a part of the 'ENS DAO voters' group in one way or another:
function balanceOf(address account) public view virtual override returns (uint256) {
    bool hasZKAttestation = ATTESTATIONS_REGISTRY.getAttestationValue(
      ZK_ENS_VOTERS_ATTESTATION_COLLECTION_ID,
      account
    ) > 0;
    bool hasPublicAttestation = ATTESTATIONS_REGISTRY.getAttestationValue(
      PUBLIC_ENS_BAYC_ATTESTATION_COLLECTION_ID,
      account
    ) > 0;
    return hasZKAttestation || hasPublicAttestation ? 1 : 0;
  }
