About this app

Sign with Absolute Certainty.

Safe OpenSig is a professional grade verification instrument for enterprise Safe signers. It provides a dedicated, isolated environment to verify the integrity of every transaction before it reaches your signing device.

Eliminate the Blind Signing Trap: Most signing flows rely on centralized interfaces and "black box" logic. Safe OpenSig replaces trust with mathematical proof. By reconstructing transaction intent locally, you eliminate the risk of browser-based phishing, UI-injection attacks, and malicious payloads.

Key Features:
- Trustless Simulation: Preview balance and account changes via a private, local execution engine.
- Hardware Emulation: View a 1:1 digital mirror of your Ledger Nano S, X, or Pro screen to confirm physical parity before you sign.
- Cryptographic Integrity: Verify transaction data against the blockchain state using local Merkle proofs, no reliance on third-party providers.
- Enterprise Privacy: Your data never leaves your device. No telemetry, no tracking, and no hidden transaction fees.

Safe OpenSig is not a wallet; it is the lens that makes the Safe ecosystem safe for institutional use.

Built for Professional Treasuries:
- Open Source & Vendor Neutral
- Local-First Architecture
- Private RPC Support
