Twitter founder Jack Dorsey has publicly supported the idea of integrating Bitcoin into Signal Messenger for direct peer-to-peer (P2P) payments.

On April 10, Dorsey posted on X, suggesting that the encrypted messaging app should consider using Bitcoin to power its financial transactions.

He wrote:

“Signal should use bitcoin for p2p payments.”

His remark was a response to an earlier post from a Bitcoin developer called Calle. Calle proposed that Signal could become even more useful by enabling Bitcoin payments, particularly by leveraging its secure, privacy-focused architecture.

According to him, Signal already offers a highly private communication environment, making it ideal for transferring digital value without relying on an entirely new blockchain. He highlighted BTC as a suitable option, suggesting it could work seamlessly within Signal’s infrastructure.

Why Bitcoin fits Signal

Signal has long been recognized for its commitment to privacy and security.

Signal is an open-source platform with end-to-end encryption that ensures only the sender and recipient can access a conversation’s contents. It does not retain any message data, making it a preferred choice for users seeking a secure messaging experience.

With around 70 million users globally, Signal’s user base is modest compared to giants like WhatsApp and Telegram. However, its reputation for privacy sets it apart.

So, adding Bitcoin functionality would reinforce this identity, offering a decentralized method for users to send funds directly and securely.

Such a move could also strengthen Bitcoin’s use case beyond just being a store of value, positioning it as a real-world tool for everyday digital interactions.

Considering this, Lightspark CEO David Marcus encouraged more non-financial platforms to explore Bitcoin as a foundational protocol for transferring money, comparing it to the role TCP/IP plays in online data transmission.

According to its website, Signal supports crypto payments with MobileCoin (now Sentz) for in-app transactions.
