Mobile transaction signing
Mobile signing. Local policy checks.
A dedicated mobile signing client validates and approves transactions, with every signature produced on-device.
On-device validation
The policy engine refuses to produce a signature for anything that breaks your rules.
Approve on the go
Review and approve or reject pending transactions from your phone, wherever you are.
Keys never leave the device
Signing happens locally, and key material is never exposed to a server.
Clear, decoded prompts
See exactly what you are approving, including amounts, recipients, and contract calls, before you sign.
