In 2014, Proton launched Proton Mail — a secure, encrypted email service that quickly grew into one of the largest privacy-focused communication platforms in the world. By giving users full control over their data through end-to-end encryption, Proton Mail empowered millions to reclaim their digital privacy from intrusive tech giants. Over a decade later, that same mission has evolved beyond email.
In 2024, Proton introduced Proton Wallet in early access — a self-custodial Bitcoin wallet designed to bring the same level of security and simplicity to personal finance. Just as Proton Mail made encrypted communication accessible, Proton Wallet aims to make secure, private, and user-controlled Bitcoin ownership available to everyone.

Why Bitcoin Is the Foundation of Financial Sovereignty
Bitcoin was created as a decentralized alternative to traditional financial systems — a digital currency not controlled by banks, governments, or corporations. Its fixed supply of 21 million BTC and transparent blockchain make it resistant to inflation and censorship. But for all its revolutionary potential, Bitcoin remains difficult for most people to use safely.
Many users rely on centralized exchanges or investment funds to hold their Bitcoin, unknowingly sacrificing control and security. While these services offer convenience, they also introduce risk: if an exchange is hacked or collapses, users can lose everything. History is filled with cautionary tales — from Mt. Gox to FTX — proving that entrusting your assets to third parties is inherently risky.
Proton Wallet addresses this by putting true ownership back in your hands. As a self-custodial wallet, it ensures you — and only you — control your private keys. No intermediaries. No hidden access. Just complete financial autonomy.
The Barriers to Bitcoin Adoption — And How Proton Wallet Removes Them
Despite growing awareness, Bitcoin still faces major adoption hurdles:
- Complexity: Setting up secure wallets, managing long public addresses, and understanding seed phrases can overwhelm new users.
- Security risks: Copy-paste mistakes or "address poisoning" scams can lead to irreversible loss of funds.
- Lack of privacy: Most wallets expose transaction history and balances to third parties.
These challenges discourage mainstream users from taking control of their Bitcoin. Instead, they turn to custodial services — defeating the purpose of a decentralized currency.
Proton Wallet was built to eliminate these barriers. Drawing from the lessons of Proton Mail’s success in simplifying encryption, the team designed a wallet that’s both secure by default and simple by design.
Self-Custody Without the Complexity
With Proton Wallet, you always own your Bitcoin. Your private keys are encrypted on your device using the same battle-tested technology behind Proton Mail. Even Proton cannot access your funds.
Each wallet comes with a standard 12-word recovery phrase — the universal key to your Bitcoin. Store it securely, and you’ll retain access to your assets forever, regardless of what happens to the Proton platform.
This means:
- You’re not locked into one service.
- You can transfer your Bitcoin to any compatible wallet at any time.
- Your assets remain under your control — even in worst-case scenarios.
Privacy Built Into Every Transaction
Proton believes privacy is a fundamental right — not just in communication, but in finance. That’s why Proton Wallet minimizes data collection and encrypts sensitive information like transaction notes and messages before they leave your device.
Unlike most wallets that expose your transaction history to servers or third parties, Proton cannot see:
- How much Bitcoin you hold
- Who you send funds to
- Your personal notes or memos
For full transparency, the security model is publicly documented — because trust should be earned through verifiable design, not blind faith.
Bitcoin via Email: A World First
One of Proton Wallet’s most innovative features is Bitcoin via Email — a breakthrough that makes sending Bitcoin as easy as sending a message.
Instead of copying long, error-prone Bitcoin addresses, you can send BTC directly to someone’s email address — as long as they have a Proton Wallet. The system handles all cryptographic complexity behind the scenes.
Additional benefits include:
- Automatic address rotation for enhanced privacy
- Built-in invitation system for non-users
- End-to-end encrypted transaction metadata
If your recipient doesn’t have Proton Wallet yet, they’ll receive an invite to sign up — along with free access to Proton Mail, extending privacy beyond finance into communication.

Open Source: Trust Through Transparency
True security requires transparency. That’s why Proton Wallet is fully open source. The code is publicly available on GitHub, allowing independent developers and security researchers to audit every line.
This aligns with the core ethos of both the Bitcoin and Proton communities: Don’t trust. Verify.
By making the wallet open source, Proton invites scrutiny — strengthening trust and ensuring long-term accountability.
