Safe OpenSig
Read full descriptionHide full description
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

Give text a voice—entirely on your iPhone. FrankenTTS is a private, on-device text-to-speech and voice-cloning playground powered by a pure-Rust speech engine. After a one-time 1.86 GB model download, synthesis runs locally with no cloud inference. • Choose from built-in voices • Clone a voice from a short microphone recording, with a live level meter and automatic background-noise removal • Keep cloned voices in a private on-device voice library; rename, re-record, or delete them whenever you like • Share and import FrankenTTS voice cards—each carries a compact 4 KB voice fingerprint, never the original recording • Generate speech with an editable random seed • See the measured real-time factor for every run • View the waveform, play audio, and share compact M4A files • Turn generated speech into a branded MP4 video • Resume interrupted model downloads with SHA-256 verification Privacy is the default: entered text, microphone audio, voice fingerprints, imported pictures, and synthesized speech are not uploaded. Enrollment recordings are discarded after their on-device voice fingerprint is computed. Voice-card sharing and media export happen only when you explicitly choose them. Only clone or share voices you have the right and consent to use. A recent high-memory iPhone is strongly recommended.
