Is UTXO Wallet non-custodial?

Yes. UTXO Wallet never stores your seed phrase or private keys on any server. Keys are generated on your device, encrypted locally, and never leave the device unencrypted.

Which blockchains does it support?

Bitcoin (native and SegWit), all EVM-compatible chains (Ethereum, Polygon, Arbitrum, Optimism, Base, BSC), and Solana.

SafeSign is a local approval-review layer. Before any signature, approval or transaction is sent to your wallet for confirmation, SafeSign decodes it and explains in plain language what is being requested — including detecting unlimited token approvals and suspicious contract patterns.

Where can I download UTXO Wallet?

Chrome / Edge / Brave extension via the Chrome Web Store and Edge Add-ons (pending review). Android via Play Store (in progress). Windows via signed desktop installer (in progress). Internal beta APK is available now.

Is the source code public?

The security-critical components will be open-sourced before public launch. The UTXO Security Core engine has its own public documentation and external audit roadmap.

How UTXO Security Core works

A local defensive engine that runs between your browser, apps and your wallet — classifying risk, explaining context and requiring your decision before any sensitive action.

→

Request Capture

Extension/app intercepts connect, sign, approve, send and chain requests before wallet confirmation.

→

Local Analysis

Security Core classifies the domain, method, contract data, approval scope and message intent — all locally, never sent to a server.

→

SafeSign Explanation

Guard SafeSign turns raw wallet requests into human-readable risk context: what it does, what it costs, what it grants.

User Decision

You continue, review or reject. The system never signs or broadcasts on your behalf.

UTXO Guard

UTXO Guard Integration

Guard SafeSign turns raw wallet requests into human-readable risk context. Unlimited approvals, raw signatures and unknown contract calls are flagged and explained before you confirm.

Explore UTXO Guard →

Domain Intelligence

Recognizes phishing sites, identifies official domains and flags suspicious contract sources before you connect.

Approval Analysis

Detects unlimited token approvals, large allowances and spender contracts — explained in plain language.

Signature Decoding

Decodes raw signatures, message hashes and permit2 approvals into human-readable explanations.

Contract Inspection

Analyzes contract method calls, parameters and risk patterns before any transaction is submitted.

Every Platform

One wallet, separate signed install channels.

The website now routes users to status and release gates until packages are proven safe and real.

Browser Extension

Release gate required

MV3 extension channel will return after the signed bundle passes review, loads correctly and remains read-only around wallet data.

Release Gate

Android

Security packaging required

Production requires release signing, Play Integrity, Android Keystore/StrongBox where available, biometrics and anti-tamper checks.

Android Rules

Windows

Installer paused

Windows setup returns only after the real app opens after install and wallet safety rules are verified. No empty shell distribution.

Installer Checklist

iOS

Roadmap

Requires Apple certificates, provisioning profiles, entitlements, TestFlight review and wallet-specific compliance checks.

Security rules

Wallet packages cannot bypass the safety model.

A wallet release is stricter than a normal app release: it needs packaging, key-handling review, signed channels and manual confirmation tests.
