Coinkite opens arca preorders for limited first batch

Coinkite has opened $99 reservations for arca, a physical digital safe designed to store recovery codes, signing keys, inheritance instructions, and other critical secrets. The first batch is limited and is targeting January 2027, with tentative pricing starting at $669 per unit.

Why it matters: - arca is designed to reduce the risk of losing access to digital assets, accounts, and business systems when secrets are scattered across phones, notebooks, cloud drives, and employees. - The product is aimed at both individuals and companies that need a physical custody layer for recovery material, signing keys, and continuity instructions. - The reservation structure gives early buyers a place in a limited first batch while locking in tentative early-bird pricing.

What happened: - Coinkite opened pre-order reservations for arca on July 23, 2026. - A $99 USD partial prepayment per unit secures a reservation in the first batch. - The first batch is targeting January 2027. - Coinkite describes arca as a physical digital safe for secrets that people and businesses cannot afford to lose.

The details: - arca is intended to protect seed words and wallet recovery material, account recovery codes and passwords, signing material and business keys, emergency instructions and inheritance notes, operational runbooks and team recovery paths, and important encrypted files. - For Bitcoin and crypto users, arca can hold wallet recovery material, exchange recovery codes, signing policies, and continuity instructions. - arca is being built to run multiple security services inside one physical custody boundary. - Planned functions include an embedded password-manager server, an embedded COLDCARD signing emulator, HSM functions for approved signing and cryptographic operations, and policy-controlled access for people, services, and authorized AI agents. - The password-manager layer is meant to handle daily credentials. - The continuity layer is meant to protect root material, recovery instructions, and policies needed when a normal account, device, place, or person is unavailable. - Coinkite says these services remain under development, and final interfaces and scope may change before production. - Business use cases include sharing access to selected secrets without copying them into chat or email, separating credentials by team or project, keeping encrypted copies across trusted locations, preserving continuity when key people leave or become unavailable, and applying policy to key operations through HSM functions. - arca is also being built for inheritance and emergency access, with selected secrets, keys, documents, and instructions assigned to chosen people. - A planned dead-man switch could make a selected recovery path available after defined inactivity or release conditions. - The company says the dead-man switch is meant to release the right material to the right person, not expose the whole vault. - The exact policy, authentication, and release mechanics remain in development. - arca does not determine whether someone has died and does not replace legal estate planning.

Between the lines: - arca appears to sit between a password manager, a hardware security module, and a succession planning tool. - The product framing suggests Coinkite is targeting users who want physical control over secrets without giving up the ability to sync or delegate access across locations. - The design also reflects a push toward compartmentalized access, which matters for families, startups, and crypto operations where one lost credential can trigger a wider failure.

What's next: - Coinkite says the hardware design and specifications will likely change as arca moves through manufacturing. - Current hardware targets include a Rockchip RK3328 host running FreeBSD, an Arm Cortex-M33 security controller with TrustZone, ATECC608C and DS28C36BQ+T secure elements, a secure real-time clock, a motion sensor, an active tamper-detect circuit, two USB power inputs, Power Over Ethernet, and an internal UPS. - Planned features also include reproducible deterministic builds and decoy PIN paths. - Tentative pricing is $669 USD for one unit, $539 USD each for two units, and $499 USD each for three or more units. - The reservation page is the Coinkite Store listing, and more information is available at arcasafes.com. - arca is coming from the same Coinkite shop behind COLDCARD, OPENDIME, TAPSIGNER, SATSCARD, BLOCKCLOCK, and COLDPOWER.

The bottom line: - Coinkite is betting that physical custody for digital secrets will appeal to users who want stronger recovery, inheritance, and business-continuity options than software-only tools can provide.
