Ambire Ice Puts Safe Owner Changes and Approval Thresholds on the Signing Screen
Ambire says its Ice hardware wallet will decode Safe transactions and flag changes to account control. The design targets the decisions signers make before authorizing an action.

Dextape brief
Ambire has introduced Ice, a hardware wallet built around Safe accounts, according to a product announcement dated October 30. The device can decode Safe actions such as transfers, token approvals and transaction batches, and it warns when a transaction changes owners, signature thresholds or modules. Signing is listed over USB, Bluetooth and QR codes. The article stresses that these are company claims, not an independent finding that every transaction is read correctly. It notes that a threshold sets how many owner confirmations are required, and that Safe documentation warns a malicious module could take over an account. The piece argues that testing should cover unusual calls, nested batches and cases where the device cannot confidently describe an action.
Why it matters: It shows how account control changes can be surfaced at the signing step, where authority over a shared wallet is actually granted.
