Ambire introduces Ice, a hardware wallet designed to make Safe transactions readable

Reading the actions before signing

On October 30, 2026, Ambire introduced Ice, a hardware wallet intended for Safe accounts and use with its own wallet. The product particularly targets multisignature wallet operators and project treasuries. Its stated goal is to make smart contract operations easier to understand at the point of authorization. The device is designed to reconstruct a Safe transaction and display its individual actions on screen, instead of presenting a signing request whose contents remain difficult to interpret.

Transfers, token approvals and batched operations are among the items the company says it can display. It also mentions warnings concerning a Safe account's owners, signing threshold or modules. These settings matter when understanding what an authorization actually changes. Displaying transaction details gives the signer additional information; it does not mean every user will automatically detect malicious intent or understand every consequence of a complex contract.

Three connections and a hardware disconnect

The device provides for communication over USB, Bluetooth or QR codes. A hardware switch is intended to disable USB data and cut Bluetooth power, allowing offline signing through animated QR codes. These modes accommodate different setups: a workstation, a phone or an isolated procedure. The separation between connectivity and signing needs to be understood in practical use. A device that can operate without a radio connection does not, by itself, guarantee the reliability of every operation presented to it.

Ambire also describes an architecture combining two secure elements supplied by NXP and Infineon, with hardware plans and software open to inspection. The transparent enclosure exposes the components, and the firmware derives from Trezor's open-source code. These are the announced design choices. They do not replace independent assessments of the final product, key generation, assembly or how displayed information corresponds to the data actually signed.

Updated preorder terms and delivery timetable

The initial post announced 200 preorders at $119 and shipping in early 2027. When checked on November 1, the official reservation page said that first batch was sold out. It offered a second batch of 200 devices at $159, with a $10 deposit credited toward the total, and delivery expected within up to six months. These terms update the initial commercial presentation; they do not describe a product available for immediate delivery. Applicable conditions and the actual timetable still need to be checked before ordering, particularly for the destination country.

Finally, the post-quantum discussion concerns a future development: adding a Safe owner using an appropriate signature depends on further work and network support. Presenting Ice as already protected against every quantum scenario would therefore go beyond the announced scope. The developments to watch first are readability of Safe operations and implementation of signing modes. The first devices shipped and their assessments will allow these features to be evaluated beyond the commercial presentation.
