Jack Dorsey, cryptocurrency entrepreneur and former Twitter CEO, has called on secure messaging app Signal to integrate Bitcoin (BTC) for peer-to-peer (P2P) payments.
On April 9, Dorsey replied to a post on X by Bitcoin developer Calle, who suggested BTC would be ideal for Signal’s private messaging structure. Dorsey agreed, saying: “Signal should use Bitcoin for P2P payments.”
Industry Leaders Back the Call!
Dorsey’s suggestion received support from prominent figures like former PayPal president David Marcus, who stated, “All non-transactional apps should connect to Bitcoin.”
These endorsements reflect growing sentiment that Bitcoin should be utilized not only as a store of value, but also as a practical payment network. Dorsey believes BTC needs real-world use cases to ensure its future success.
Signal Only Supports Sentz (Formerly MobileCoin)
Launched in 2014, Signal is an open-source, encrypted messaging platform offering instant messages, voice, and video calls.
Currently, the only in-app payment option is Sentz (formerly known as MobileCoin – MTCN), a privacy-focused ERC-20 token.

According to Signal’s website, the token is still listed under its old name, MobileCoin.
Backed by top crypto investors like BlockTower Capital and Coinbase Ventures, Sentz aims to offer a “fast, private, and user-friendly” crypto payment experience.
MobileCoin Integration Has Been Controversial
Signal’s 2021 integration of MobileCoin sparked backlash due to alleged ties between the app’s founder and MTCN, questions around the coin’s issuance, and abnormal price movements prior to the announcement.
Social Media Apps Historically Prefer Altcoins
Signal is not alone in favoring altcoin payments over Bitcoin, which its anonymous creator Satoshi Nakamoto envisioned as a P2P payment system.
While David Marcus now supports Bitcoin for all non-transactional apps, he previously led Meta’s ill-fated crypto project, Libra.
Telegram is actively promoting the use of Toncoin (TON) across its ecosystem — a token tied to its founders but not directly operated by Telegram.
Meanwhile, Elon Musk’s “everything app” X has long been rumored to launch its own token, but Musk denied these claims in August 2023.
