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
