A DEDICATED SELF-CUSTODY HARDWARE WALLET
Control begins with a decision.
11Dvault is a self-custody hardware wallet in development. The planned air-gapped device keeps signing on dedicated hardware while a companion app prepares and broadcasts transactions without receiving your private keys. Review each request before approving it on the device.
Dedicated hardware wallet. No exchange or trading services.

THE PRODUCT / 11DVAULT DESIGN
The intended wallet. In clearer detail.
11Dvault is being planned around the same self-custody design direction: offline signing, user-controlled recovery and a companion app that prepares transactions without receiving private keys. The items below are intended features and design decisions to verify, not functioning or certified product specifications.
| Planned item | Design intent and caveat |
|---|---|
| 01 / OFFLINE SIGNINGAir-gapped by design | No USB data path, Bluetooth or Wi-Fi is planned for signing. The companion app prepares and broadcasts transactions; the device reviews and signs a payload without exporting private keys. |
| 02 / KEY PROTECTIONSecure element and open firmware | The product plan calls for keys generated and sealed in a certified secure element, with published, reproducible firmware. Component certification and build verification must be documented for the finished device. |
| 03 / NETWORKSMulti-chain support | Bitcoin, Ethereum and major EVM networks are planned at launch, with additional networks through signed firmware updates. Final compatibility will be confirmed after implementation and testing. |
| 04 / RECOVERYShamir backup | The intended recovery model uses Shamir-style shares kept in separate places, with a user-chosen threshold. Its final format and independent compatibility will be published before ordering. |
| 05 / ACCESSDecoy passphrase | A second passphrase is planned to open a separate wallet. The actual user experience and threat-model limits will be documented when the design is validated. |
| 06 / PHYSICAL DESIGNTamper-evident construction | The design direction calls for a milled shell and sealed packaging so interference before first use is easier to notice. No physical design eliminates every tampering risk. |
| 07 / PRIVACYNo unnecessary telemetry | The planned device has no telemetry channel; the intended companion app needs no login or cloud recovery. Final software behavior and data handling will be documented before release. |
| 08 / USER CONTROLReview on the device | Users are meant to inspect transaction details and approve signing on the device. The companion app should never receive a private key, while approval of a harmful request can still cause loss. |
NO DEVICE TELEMETRY
The intended hardware has no analytics channel to report wallet activity.
NO TRACKING
The planned app does not require an account, identity check or linked address profile for its core operation.
NO CLOUD
Backup material stays with the user rather than in a project-operated cloud account.
These are planned device and app behaviors. The live website and any email request involve separate data handling described in Privacy.
Fig. 02 — Exterior detail
Prepare elsewhere. Decide deliberately.
This is a general explanation of hardware-wallet signing, not a verified 11Dvault device specification or a setup guide.
- 01 — PREPARE
See the transaction.
A companion app can prepare a request showing the destination, amount, network and fees. It may be compromised, so these details still deserve careful checking.
- 02 — REVIEW
Check before approval.
A dedicated device may display details for you to compare with your intent. Inspect addresses, network, amount and any permissions requested.
- 03 — AUTHORIZE
Sign with intent.
With 11Dvault, signing occurs on the device and private keys are not shared with this website. An approval can still be harmful if the transaction itself is unsafe.
THE SIGNING BOUNDARY
Why dedicated hardware?
A software-only wallet may keep signing material on a connected phone or computer. The 11Dvault plan separates signing onto a dedicated device while the companion app prepares and broadcasts the request. Software wallets vary; neither arrangement makes a harmful approval safe.
- Keys:
- planned to remain on the 11Dvault device instead of being handed to the companion app.
- Review:
- the user should compare transaction details and explicitly approve on the device.
- Recovery:
- intended split-share backup under user control, with final format and compatibility still to be verified.
A USEFUL CHECK TODAY
Pause before any approval.
When evaluating any self-custody transaction, compare the destination, network, amount and fees with what you intended. For a contract request, read the permissions and limits. A device cannot make a harmful request safe simply because you approve it there.
THE PRODUCT BOUNDARY
What 11Dvault is — and what it is not.
Intended: a dedicated hardware wallet for self-custody signing, with the user in control of their own keys and decisions.
Not offered: an exchange or any service to buy, sell, exchange, swap or trade crypto assets. We do not hold customer funds or manage investments.
Different people. The same careful questions.
These examples describe situations people consider when evaluating a hardware wallet. They do not claim that 11Dvault already supports a particular workflow or network.
- 01 / PERSONAL
Protecting a personal backup
Consider where recovery information would be kept, who could access it, and what would happen if the device or backup were lost.
- 02 / LONG TERM
Checking before an infrequent transfer
When you transact rarely, revisit addresses, network choices and permissions instead of relying on a familiar-looking app screen.
- 03 / TEAMS
Defining who can authorize
A DAO or business treasury needs defined approvals and recovery across contributors. The product plan includes threshold-based control; the finished workflow has not been tested or released.
- 04 / BUSINESS
Documenting reserve controls
A business can plan custody roles, review records and recovery responsibilities. 11Dvault intends to support deliberate authorization; final organizational features remain unverified.
Fig. 03 — The 11Dvault device
Your backup matters. So does every approval.
A hardware wallet cannot guarantee that a destination is trustworthy, a contract approval is safe, or a transaction can be reversed. Losing or exposing recovery material can mean permanent loss or theft. Assets remain on their networks; they are not stored inside a device.
Understand the risks ↗Progress needs evidence.
11Dvault is presently in development. The stages below describe what should be disclosed as work progresses; they are not completed milestones, guaranteed specifications or a production schedule.
- NOW / DESIGN
Define the questions.
The 11D Security Design Goals frame decisions about key handling, transaction review, recovery and verification. No device is available for ordering or testing by users.
- NEXT / DESIGN DECISIONS
Publish confirmed choices.
When design work supports it, publish actual architecture, compatibility and recovery details. Until then, no chip, connection method, open firmware or supported network is promised.
- BEFORE ORDERS / EVIDENCE
Show what has been tested.
Share substantiated test results, independent findings if obtained, final specifications, pricing, delivery regions and terms before accepting orders. Plans can change as development continues.
Expected availability: Q2–Q3 2027. This is an estimate, not a commitment to ship, open orders or complete any specific feature by that time. Read the full pre-launch disclosure ↗ · Use the 11D evaluation worksheet ↗

Before you go further.
What exactly is 11Dvault?
11Dvault is a dedicated self-custody hardware wallet in development. Its intended purpose is to help users review and authorize transactions while keeping private-key signing on dedicated hardware. The eleven security dimensions describe design goals; final specifications and supported networks have not been confirmed.
Is 11Dvault an exchange or trading service?
No. 11Dvault is a hardware-wallet project in development. Neither this website nor the proposed device offers buying, selling, exchanging, swapping or trading crypto assets. We do not hold funds or manage investments.
Can I buy or reserve a device now?
No device can be ordered or reserved for purchase yet. You can register interest in the first planned production run through the founder list. The list is free; its number counts interest requests, not allocated devices. There are no deposits, confirmed prices, shipping commitments or guaranteed launch dates. Expected availability is Q2–Q3 2027, an estimate subject to development and testing.
When will pricing and shipping be announced?
Founder pricing is planned for the first production run. People on the founder interest list will be notified when the offer, price, eligibility, regions and ordering terms are published. Joining the list does not qualify anyone automatically for a price or allocate a device. Q2–Q3 2027 is an estimated availability window, not a commitment.
Which networks and features are supported?
The product plan includes Bitcoin, Ethereum and major EVM networks at launch, air-gapped signing, an open-firmware direction and user-controlled recovery. These are planned capabilities, not verified support on a released device. Final compatibility and specifications will be published after implementation and testing.
Will 11Dvault ask for my recovery phrase?
No. This informational website has no wallet connection, account, key recovery, transaction signing or payment feature. Never email a recovery phrase, private key, PIN or password.
What if the 11Dvault project stops?
Self-custody requires a backup and a compatible recovery path that you control. We have not finalized or verified 11Dvault recovery formats or compatibility, so we cannot promise that another wallet will restore a future 11Dvault backup. We will disclose the actual recovery method before taking orders.
Will the firmware be open or independently tested?
Open, reproducible firmware and independent scrutiny are goals for the proposed wallet. No firmware release, reproducible build, audit or certification is confirmed yet. Results will be published only if and when they exist.
Where can I see development progress?
This site explains the current design and the disclosures expected before orders. Product news may be requested by email, but it does not reserve a device. We will add verified milestones here as they become available.
What if I lose my device?
Recovery depends on the wallet’s actual backup method. A secure compatible backup may help restore access, but no 11Dvault recovery method is finalized here. Loss or exposure of recovery material can cause irreversible harm.
Reserve your spot on the founder list.
