The vault is the last place an adversary looks when a vault is the last place a human would hide something important. ArcaKey is both halves of that pair, rendered as software.
The Arca · Key wordmark is set once in champagne-italic, framed by corner fillets that echo the cut of a signet. It appears on the vault door, the attestation seal, and the statement of fees — and nowhere else.
Every tier is end-to-end encrypted, post-quantum, and TEE-isolated. The tiers differ in model menu depth, frontier headroom, compliance posture, and dedication of infrastructure — never in privacy.
A preview of how the Arca · Key vault reads in use — ink, ivory, and a single restraint of champagne. The aesthetic of a private bank, in digital form.
