7 Best Open-Source Crypto Wallets in 2025

Imagine having one of the best open-source crypto wallets that feels just right in your hands. Trezor Safe 5 offers a reliable wallet experience with its public and transparent code and user-friendly design.

Its 1.54” scratch-free gorilla glass color touchscreen protects your screen and makes navigating your digital assets a breeze. In addition, the gentle haptic feedback offers a reassuring touch with every interaction, giving you confidence as you manage your portfolio.

The beauty of Trezor Safe 5 is that its code is fully open, allowing experts worldwide to inspect and validate its security.

Plus, the wallet integrates effortlessly with the Trezor Suite application, providing a seamless and unified platform for managing your crypto. The vibrant display and intuitive interface make the process not only secure but also incredibly user-friendly.

Trezor’s dedication to openness extends beyond just one model. Both the Trezor Safe 3 and Safe 5 maintain this philosophy, keeping their code available for community review.

This means that every function, from wallet backups to key management, is accessible for verification, strengthening user trust. Trezor’s choice to use OPTIGA™ Trust M (V3) chips from a supplier that embraces vulnerability disclosures further reinforces its commitment to transparency and security.

That said, Trezor still advises users to set up a strong passphrase for optimal protection, as this feature offers an almost impenetrable layer of security, ensuring your funds remain safe.

The Trezor Safe 5’s combination of advanced features, open-source transparency, and practical design makes it an exceptional choice for those seeking peace of mind in crypto management.

Whether you’re a newcomer or a seasoned investor, its seamless integration with Trezor Suite and the focus on community trust make this wallet a reliable and secure option for your digital assets.

If you want a cold crypto wallet that blends mobility with top-notch security, the Ledger Nano X is a fantastic option.

Designed for those constantly on the move, this wallet’s Bluetooth connectivity allows you to manage your assets seamlessly, whether you’re at home or traveling. It offers the flexibility to check balances or initiate transactions without the hassle of wires, making it perfect for active users.

Ledger Nano X is especially a great option for people who want to have a portfolio with a wide diversity of coins and tokens. The hardware wallet supports thousands of digital assets, so you have plenty of choices to select from, ensuring you don't have to juggle multiple wallets.

Along with this, the wallet is equipped with an EAL 5+ Secure Element chip, adding an extra layer of protection to keep your funds safe from unauthorized access.

A significant feature of the Ledger Nano X is its commitment to transparency. A remarkable 95% of its components are open-source, which means anyone in the crypto community can inspect and validate its code.

This openness builds trust, reassuring users that the wallet has undergone rigorous scrutiny by experts around the world. It’s a way for Ledger to demonstrate that their product prioritizes user security above all else.

However, not everything in the Ledger ecosystem is entirely open. While the Ledger Live app operates on an open-source license, the operating system itself has protected code segments.

This is because Ledger has an agreement with STMicroelectronics to safeguard the design of the secure element, ensuring its integrity while balancing transparency. This approach ensures that while most of the wallet is open for community review, the critical elements that need additional security remain protected.

Furthermore, they partner with respected security labs for third-party audits, confirming that no vulnerabilities or backdoors exist in their system. This commitment to external validation offers users an added layer of confidence.

Despite the advanced technology, the Ledger Nano X emphasizes the importance of user responsibility. With its user-friendly Bluetooth integration and top-notch security features, it’s designed for those who value both convenience and safety.

It serves as a reminder that while the wallet provides robust protection, managing crypto securely is a shared effort between the device and its user. Whether you’re a seasoned trader or just starting, the Ledger Nano X offers a secure and versatile solution that fits seamlessly into your lifestyle.

If you're searching for the best open-source wallet that combines simplicity and top-tier security, the Trezor Model T is one of the best choices.

For additional protection, you will always need to set up a PIN and passphrase, giving you multiple layers of security to keep your funds safe.

What makes this open-source cryptocurrency wallet stand out is its transparency. The code is open for the community to check, meaning every safety feature has been tested and approved by experts.

The Trezor Model T also includes advanced features such as two-factor authentication (2FA) and compliance with the FIDO2 Standard, an advanced open authentication standard developed by the FIDO Alliance.

The open-source nature of the Trezor Model T extends beyond software. Its design is also open-source, offering DIY guides for building your own hardware wallet. This openness brings several benefits, including community testing, transparency, and the ability to mitigate hardware obsolescence.

The community-driven approach allows developers to verify the software’s integrity and share knowledge freely, ensuring that users are protected from threats. With features like a 1.54-inch color LCD touchscreen, USB-C connection, and on-device transaction confirmation, this wallet is designed for ease of use.

The Ledger Nano S Plus is a compact yet powerful cold wallet, earning its place as one of the best open-source crypto wallet options available today. With its sleek design, it’s easy to carry around, yet it packs a punch, supporting over 5,500 digital assets.

In addition, this open-source wallet includes an EAL 6+ Secure Element chip, ensuring your cryptocurrencies are kept safe, no matter how many assets you manage.

Just like the Ledger Nano X, this model is about transparency—95% of its components are open source. This allows the community to check and verify its security, giving you peace of mind knowing your wallet is safe and trustworthy.

However, it’s essential to note that while Ledger Live and several parts of the OS are open source, the operating system’s code related to the Secure Element remains closed. This is because the Secure Element technology is protected by intellectual property rights, ensuring the chip’s design remains secure and proprietary.

Ledger’s approach focuses on balancing transparency and security. To achieve this, they employ third-party security labs to audit their systems, including the closed-source parts, to ensure there are no vulnerabilities or backdoors.

Each OS release undergoes this audit, allowing users to trust the integrity of the device. For added security, Ledger offers a “genuine check” feature, verifying the authenticity of your device before use.

In short, the Ledger Nano S Plus provides a secure and reliable option for users who value both open-source transparency and high-level protection for their digital assets.

If you're searching for one of the best open-source crypto wallets that combines advanced security with multi-chain access, Kraken Wallet might be a good choice. This open-source platform integrates biometric authentication and encryption technology, giving you top-tier protection for your crypto and NFT assets.

Imagine having all your digital wallets and assets in one place, from Bitcoin and Ethereum to Solana—it’s all possible with Kraken Wallet.

In addition, by being fully open source, Kraken Wallet allows the community to verify and improve its security, ensuring users can trust the system they’re using.

It offers self-custody, so you have complete control over your digital assets without any third-party interference. This model not only provides security but also empowers users to manage their assets independently.

Kraken Wallet supports unified multi-chain access, allowing seamless interaction with networks such as Arbitrum, Optimism, and Dogecoin from one platform.

The platform makes it easy to manage DeFi positions, trade NFTs, and confirm transactions, thanks to this multi-chain integration.

The Kraken Wallet ensures that switching between networks or viewing transactions is seamless, eliminating the need to juggle multiple apps.

This multi-chain capability enhances scalability and flexibility, promoting greater customization in application development. It also ensures that the wallet remains secure, with only authorized entities able to access network functionalities, reducing risks associated with unauthorized access.

Beyond its basic features, Kraken Wallet also prioritizes privacy. The wallet ensures that your IP address and personal data are never tracked or shared with third parties, so you can transact confidently.

Additionally, Kraken Wallet integrates with popular decentralized apps (dApps) and protocols, making it a versatile tool for Web3 exploration. From DeFi interactions to NFT management, everything can be managed through a single interface.

Moreover, Kraken applies a Proof of Reserves (PoR). It's a method used by cryptocurrency wallets and exchanges to demonstrate that the assets they hold for their users are fully backed by actual funds.^[1] This approach enhances transparency by allowing users and external auditors to verify that the platform’s liabilities (user balances) are matched by the reserves held by the institution.

For example, platforms like Kraken use PoR protocols to regularly publish cryptographic proof showing they possess sufficient assets to cover user balances. They achieve this without revealing sensitive information about the accounts or compromising user privacy, reinforcing transparency and reliability in their services.

By integrating Kraken’s industry-leading security measures, including 24/7 customer service and deep liquidity, Kraken Wallet delivers a reliable and powerful tool for all crypto enthusiasts.

With support for over 2,000 cryptocurrencies and seamless integration across multiple blockchains, Kraken Wallet provides an all-in-one solution for digital asset management. It’s not just a wallet; it’s a passport to the decentralized web, ensuring that your crypto journey is secure, private, and entirely under your control.

Now, SafePal has various wallets available, both hardware and software. However, in this chapter, I will specifically cover its SafePal X1 cold wallet.

Let’s start with what makes this device stand out. Its Bluetooth connectivity means you can manage your assets wirelessly.

Whether you’re checking balances or authorizing transactions, you have the freedom to do it all without being tied down by cables. This is particularly handy if you’re someone who likes to manage their crypto on the move.

Now, what is cold storage, and why is it important? In the world of cryptocurrencies, cold storage is a method used to keep private keys—essentially your access keys to your funds—offline.

By keeping them away from the internet, you’re significantly reducing the risk of hacking or online threats. Think of it as storing your most valuable possessions in a high-security vault that only you can access. It’s the best way to protect your assets for the long term, keeping them safe from potential vulnerabilities that come with internet-connected devices.

With over 10 million users already trusting SafePal, the X1 Wallet is gaining traction, especially as it transitions into a fully open-source ecosystem. This shift is significant because it allows the community to review and verify the wallet’s security measures.

By opening up its code, SafePal invites transparency, building trust and confidence among its users. Key functions like Bluetooth connectivity, smart contract approvals, and private key storage are already available for review on GitHub, showcasing SafePal’s commitment to openness.

When it comes to security, SafePal leaves no stone unturned. The X1 Wallet is equipped with advanced features like an anti-tampering mechanism and a CC EAL5+ Secure Element chip, ensuring your funds are protected from unauthorized access.

User experience is another area where the SafePal X1 excels. It features a larger 1.8-inch screen and a 12-button D-Pad, making navigation and transaction confirmation simple and intuitive.

The wallet’s sleek and minimalistic design also makes it incredibly portable, even more so than its predecessors, the S1 and S1 Pro. This means you can easily carry it with you, making it an ideal choice for those who need a secure and compact solution.

But the X1 Wallet isn’t just about what it can do now. It’s also about the future. As SafePal continues to expand its open-source initiative, users can expect even more innovation and transparency.

Overall, it’s more than just a tool for managing crypto—it’s a secure, reliable, and innovative platform designed to give you peace of mind and control over your assets.

Imagine a crypto wallet that simplifies your experience by completely eliminating the need for seed phrases. That’s where Zengo Wallet comes in, offering a fresh and innovative approach to managing your digital assets.

Instead of relying on traditional seed phrases, which can be easily lost or compromised, Zengo uses cutting-edge Multi-Party Computation (MPC) technology to provide top-level security.^[2]

This setup ensures that no single party ever holds the complete key, which means that even if one part is compromised, your assets remain secure. When you initiate a transaction, these parties collaborate to authorize it without ever reconstructing the full key, reducing risks such as hacking and theft.

Zengo’s use of institutional-grade MPC, the same technology trusted by companies like Coinbase, demonstrates its serious commitment to security. By removing the dependency on seed phrases, Zengo eliminates the common vulnerabilities associated with them, such as phishing attacks, loss, or theft.

However, its features don’t stop there. The wallet is equipped with an advanced Web3 firewall to protect you from suspicious transactions. It uses a color-coded warning system—green for safe, yellow for caution, and red for danger—so you know when to proceed and when to halt. This way, you can interact with Web3 applications with confidence, minimizing exposure to scams.

Another standout feature is Zengo’s Private Transaction Mode, which enhances privacy by generating new addresses for each transaction involving cryptocurrencies like Bitcoin or Dogecoin. This setup ensures that your transaction history is not tied to these new addresses, maintaining your on-chain privacy while keeping everything organized and easy to manage.

By using a hierarchical deterministic system, Zengo keeps all generated addresses connected to your main account, allowing you to manage them seamlessly. You won’t have to worry about tracking down multiple wallets or remembering different details—everything is accessible from one secure platform.
