Swiss tech company Proton has introduced a self-custody digital wallet supporting crypto transactions via email. Proton AG, known for its privacy-focused online services, has launched Proton Wallet, an open-source solution available on web, Android, and iOS platforms.

The wallet currently supports Bitcoin but may expand to include other currencies, including fiat, based on user feedback. The product allows users to send crypto using email addresses, even if those addresses are not linked to Proton Mail, Proton’s encrypted email service. Integrations with onramps enable users to purchase Bitcoin in over 150 countries, though specific partners remain undisclosed.

By enabling us and the entire Proton community to more easily adopt means of payment which are not controlled by centralized institutions, we better insulate Proton from the risks posed by traditional finance.

Proton is also working on a paid version called Proton Wallet Plus, which will feature Proton Sentinel, a special security program for users at higher risk of cyberattacks. Details on technical features and the release timeline are yet to be disclosed.

Founded in 2013, Proton has consistently been involved in blockchain-related initiatives. In late 2023, Proton Mail introduced a feature that automatically compares users’ public keys with intended recipients on a blockchain to ensure accurate email delivery. The mail service has held Bitcoin on its balance sheet since 2017 and continues to accept crypto payments.
