Twitter founder Jack Dorsey publicly supports the idea of integrating Bitcoin into signalling messengers for direct peer-to-peer (P2P) payments.
On April 10, Dorsey posted to X, suggesting that encrypted messaging apps should consider using Bitcoin to power financial transactions.
He wrote:
“The signal must use Bitcoin for P2P payments.”
His comments were answers to an earlier post from a Bitcoin developer called Calle. Calle proposed that enabling Bitcoin payments could make signals even more useful, particularly by leveraging a secure, privacy-focused architecture.
According to him, Signal already offers a very private communication environment, making it perfect for transferring digital value without relying on an entirely new blockchain. He highlights BTC as a suitable option, suggesting that it could work seamlessly within Signal’s infrastructure.
Why Bitcoin fits your signal
Signals have long been recognized for their commitment to privacy and security.
Signal is an open source platform with end-to-end encryption that allows only senders and recipients to access content in the conversation. Because message data is not retained, it is a preferred option for users looking for a secure messaging experience.
With around 70 million users worldwide, Signal’s user base is modest compared to giants like WhatsApp and Telegram. But its reputation for privacy highlights it.
Therefore, adding Bitcoin features enhances this identity and provides a decentralized way for users to send funds directly and safely.
Such a move can position Bitcoin use cases not only as valuable stores, but also as real-world tools for everyday digital interaction.
With this in mind, LightSpark CEO David Marcus encouraged more non-financial platforms to explore Bitcoin as the basis protocol for transferring money, comparing it to the role that TCP/IP plays in online data transmission.
According to its website, Signal supports crypto payments with Mobilecoin (now Sentz) for in-app transactions.
