Is this a BTC fork?
These guys are usually on top of any new forks. They will not add it to their search until they can build, run and confirm wallet balances on their own node.

It's not a carbon copy of BTC as the algorithm is HMQ1725 rather than SHA256, but it's based on bitcoin code.
Thanks for the link but walletchecker only checks Bitcoin, Bitcoin Cash, Bitcoin Gold and Super Bitcoin
