UKey Wallet and UKey Core 26 are two products built to work as one self-custody system. The app handles the preparation side of a transaction, while the touchscreen hardware wallet takes over the final signing step. The company positions them as two parts of a single workflow, not as separate tools.
How the Workflow Splits
The division of labor is straightforward. UKey Wallet, a multi-platform application, manages accounts, moves assets, and gives users access to Web3 services. It's the part of the system that gets a transaction ready. UKey Core 26, a hardware wallet with a touchscreen, steps in at the end to sign. That's the moment the private key is used, and it happens on the dedicated device rather than on a phone or computer.
This split means the app can be as connected and flexible as it needs to be, while the hardware wallet stays focused on one job. The company describes the two as complementary pieces of the same self-custody workflow.
What the App Handles
UKey Wallet is built for supported account management, asset transfers, and Web3 access. It's the interface users interact with most. The app prepares transactions, gathers the necessary details, and then hands off to the hardware wallet for approval. Because it's multi-platform, it's designed to work across different operating systems, though the company hasn't specified which ones.
The app's role is to make the process smooth. It's where users see their balances, initiate transfers, and connect to Web3 services. But it never signs on its own.
What the Hardware Wallet Adds
UKey Core 26 is a touchscreen hardware wallet. Its job is to take over the final signing step. That's a deliberate design choice. By moving the signature to a separate device, the workflow keeps the most sensitive action off the app and the device running it.
The touchscreen lets users review and confirm what they're signing directly on the hardware. The company hasn't detailed the screen's size or the exact confirmation process, but the positioning is clear: the hardware wallet is the final authority in the transaction flow.
One Workflow, Two Devices
The two products aren't meant to be used in isolation. UKey Wallet prepares, UKey Core 26 signs. That's the entire concept. The company hasn't said whether the hardware wallet is required for every transaction or if the app can work alone for certain actions. It also hasn't released pricing or availability details for the Core 26.
What's known is the intended use: a self-custody setup where the app handles the busywork and the hardware wallet holds the line at the signing step. The company has not yet explained how the two devices communicate or what happens if a user only has the app.
