F.A.Q

‣

If the badges are used for gating, how can we know if an address is the holder of a particular badge (let’s say L2 for example). I had a look at the contract and since all badges are in the same contract and I had both L2 and season 6 badge, my balance is 2. I did not see any obvious way to distinguish between the two batches. How can I check if an address is holder of L2 without having to know all ID’s

The balanceOf() function was mainly added to the contract for backward compatibility with EIP-721 spec. You can check who the badge's owner is by calling ownerOf() but that obviously require you to have prior knowledge of your badgeId/tokenId. It is currently unavailable for one to check the balance of an account for a specific badge directly from the contracts. We plan to support this soon. In the meantime, this is already queryable via the subgraph
