Contact
Tell us which hardware wallets are in scope. We reply within two business days with a proposed session window.
Appointments are arranged by message first. Include device models if you know them; a rough count is enough to start. For urgent device failure (screen dead, suspected tampering), say so in the first sentence so we can prioritize a shorter diagnostic conversation before booking a full review.
