When it comes to managing digital assets, choosing the right crypto wallet is crucial. Open-source crypto wallets stand out for their transparency, security, and community-driven development. Unlike proprietary wallets, open-source solutions allow anyone to inspect, verify, and contribute to the codebase—ensuring no hidden vulnerabilities or backdoors exist.

This level of openness builds trust, especially in a space where security breaches and scams are all too common. Whether you're a beginner or an experienced user, selecting a wallet that aligns with your security needs, usability preferences, and blockchain support is essential.

In this guide, we’ll explore seven of the best open-source crypto wallets available today—highlighting their features, strengths, and potential drawbacks—to help you make an informed decision.

1. Trezor Safe 5 – EAL6+ Certified Hardware Wallet

Ranked among the top open-source hardware wallets, the Trezor Safe 5 combines cutting-edge security with a sleek, user-friendly design. It's built on fully open-source firmware, meaning its code is publicly auditable by developers and security experts worldwide.

Key features:

The open-source nature of Trezor wallets ensures continuous community scrutiny, which enhances long-term reliability. Additionally, the use of OPTIGA™ Trust M (V3) chips from a vendor that supports vulnerability disclosure reinforces its commitment to transparency.

While it lacks a seed recovery service and comes at a premium price, its robust security framework makes it ideal for users who prioritize asset protection.

💡 Pro Tip: Always set up a strong passphrase for an extra layer of defense—even if your device is lost or stolen.

2. Ledger Nano X – High-Quality On-The-Go Hardware Wallet

The Ledger Nano X is designed for users who value mobility without compromising security. This compact hardware wallet supports more than 5,500 cryptocurrencies and allows wireless management via Bluetooth through the Ledger Live app.

Notable advantages:

Although Ledger’s operating system contains some closed-source elements (due to partnerships with STMicroelectronics), the company maintains transparency through third-party audits and a “genuine check” feature that verifies device authenticity.

3. Trezor Model T – Fully Open-Source Cold Wallet

For those seeking complete transparency, the Trezor Model T stands as one of the most trusted fully open-source cold wallets. From firmware to hardware design, everything is publicly available—enabling community verification and even DIY builds.

Highlights include:

Its open design not only promotes trust but also future-proofs the device against obsolescence. However, some users find it bulkier compared to newer models.

Despite its higher cost and limited asset support relative to competitors, its unparalleled openness makes it a favorite among privacy-conscious users.

4. Ledger Nano S Plus – Secure Cold Wallet Supporting 5,500+ Assets

An upgraded version of the classic Nano S, the Ledger Nano S Plus offers improved performance and broader compatibility. It supports over 5,500 digital assets and allows installation of up to 100 apps at once.

Why it stands out:

Like other Ledger devices, while parts of the OS remain closed for intellectual property reasons, regular third-party audits ensure system integrity. The “genuine check” feature adds another layer of anti-counterfeit protection.

Ideal for budget-conscious users who still want enterprise-grade security.

5. Kraken Wallet – Completely Open-Source Software Wallet

Unlike exchange-based custodial wallets, Kraken Wallet is a self-custody solution that gives users full control over their private keys. As a completely open-source software wallet, its code is transparent and verifiable.

Core benefits:

With support for over 2,000 cryptocurrencies, Kraken Wallet serves as a versatile hub for managing DeFi positions, trading NFTs, and interacting with dApps—all from one interface.

Its multi-chain architecture eliminates the need to switch between platforms, offering both flexibility and efficiency.

6. SafePal X1 – Hardware Wallet With a Friendly Design

SafePal’s X1 hardware wallet blends strong security with modern usability. Designed for both beginners and advanced users, it supports thousands of coins and offers cross-chain swaps directly within the app.

Standout features:

With over 10 million users globally, SafePal is transitioning toward a fully open-source ecosystem. Independent audits by Keylabs further validate its security claims.

While past concerns were raised about earlier models (S1), the X1 addresses many of those issues with improved design and enhanced transparency.

7. Zengo – Safe Hot Wallet With Advanced Features

Zengo takes a unique approach by eliminating seed phrases entirely through Multi-Party Computation (MPC) technology. This institutional-grade method splits your private key into multiple parts stored across secure servers and your device.

Advantages:

Backed by the same MPC tech used by Coinbase, Zengo reduces risks like phishing and theft. While some features aren’t available in all countries, its ease of use and strong security make it ideal for newcomers.
