Wallet Scrutiny last tested OneKey classic 2 months ago, and it passed all the tests except the last one. The binary they built from source doesn't match the published source code. Some other wallets fail on this step as well. For instance, Blue Wallet has done that several times. I don't have the competence to explain that, but I can see that there was some discussion about it between the Wallet Scrutiny team and OneKey on GitHub. I leave it to other people to comment on and interpret what the reasons are for failing the final test and if what OneKey said makes sense.

Besides Wallet Scrutiny, there are other researchers who test crypto wallet and perhaps it passed all their testing...
