FAQ

Hello! I am testing getNFTsForContract API(v3) at Polygon Mumbai network.

I deployed an ERC721 contract with ERC721 consecutive extension.

https://github.com/OpenZeppelin/openzeppelin-contracts/blob/master/contracts/token/ERC721/extensions/ERC721Consecutive.sol

In this contract, I minted 1000 tokens during construction, using _mintConsecutive. After that I tried to get my token info with getNFTsForContract API, but it seems like it did not collect information regarding the tokens. Only after I manually emitted Transfer events using for loop, did the API work correctly.

Is this because Alchemy does not collect ConsecutiveTransfer event? and is there any other work around?

Thank you
