nprofile1qqs0ex2dcnv4alnzuhk3epz59aq2ragnutztlx2nqqa2fhlg44jfkygvzxqwr (nprofile…xqwr) graphene closes the operating system hole. a coldcard closes a different one, because it never touches a network at all, so a compromised phone still cannot reach the key. i run graphene as my daily phone and i still sign on separate hardware. the airgap is doing a job a phone cannot do.
