Ethereum's X Account Gets Fact-Checked by ZachXBT: 'Proton Takes Bitcoin, Not ETH, for Subscriptions'

Onchain investigator ZachXBT publicly corrected the official Ethereum X account on July 4, pointing out that privacy company Proton accepts only bitcoin, not ether, as a cryptocurrency payment option for its subscriptions.

Key Takeaways:

• • ZachXBT told Ethereum’s X account that Proton takes only BTC for subscription payments.
• • Proton’s docs reject Lightning and ERC-20 payments and require BTC at least 24 hours before bills are due.
• • Proton launched a bitcoin-only self-custodial wallet in 2024, deepening its alignment with Bitcoin.

The Callout

Replying directly to a post from Ethereum’s official account, ZachXBT wrote on X:

“Proton does not currently accept Ethereum as payment option for subscriptions only Bitcoin.

The pseudonymous investigator, known for tracing stolen funds and exposing fraud across the industry, attached a screenshot and left the correction at that, a characteristically blunt fact-check delivered to an account with millions of followers.

What Proton Actually Accepts

Proton’s own support documentation backs the investigator up with the Swiss company, best known for its encrypted Proton Mail email service and VPN, stating that users “can pay for any Proton subscription with Bitcoin,” at least where crypto is concerned.

The process is deliberately simple if manual, and all users have to do is select bitcoin at checkout, scan a QR code or copy a BTC address, and wait for network confirmations (that can take up to 24 hours). Automatic renewal is not available for bitcoin payers, so Proton advises sending payment at least 24 hours before a bill comes due.

The company’s Bitcoin alignment runs deeper than checkout options given that in 2024, Proton launched Proton Wallet, a self-custodial bitcoin storeage solution available on the web, iOS and Android (a product built around BTC exclusively, with no support for ether or ERC-20 tokens).

An Awkward Moment for Ethereum’s Payments Push

The jab lands at a sensitive time for Ethereum’s public positioning, given that its parent entity has witnessed a mass exodus of talent over the past quarter. Moreover, the Ethereum Foundation published a formal privacy commitment late last year and has since narrowed its priorities to what it calls CROPS (i.e. censorship resistance, capture resistance, openness, privacy and security). Payments adoption features prominently in the foundation’s 2026 execution plans, and the network’s marketing has increasingly courted privacy-focused users.

That is precisely why ZachXBT’s correction stung since Proton is arguably the most recognizable privacy-technology brand in the world, with services spanning email, cloud storage, passwords and VPN (and when it takes crypto, it takes bitcoin). An Ethereum marketing push that name-checks the privacy economy invites the obvious rejoinder that the sector’s flagship company routes its money over the rival chain.
