Beginning May 19, users can send and receive Bitcoin through asynchronous-like, serverless transactions that break common blockchain surveillance techniques.
Unlike traditional Bitcoin transactions, where all inputs typically belong to the sender, Payjoin v2 mixes sender and receiver inputs, disrupting the “common input ownership heuristic” chain analysts use.
This means Bitcoiners can now obscure sender/receiver relationships with just a few taps in an accessible, easy-to-use wallet – no Tor, no extra apps, no waiting for both parties to be online.
“Bitcoin is open and permissionless — but without privacy, it’s a surveillance tool,” said Vikrant Sharma, CEO of Cake Wallet. “This upgrade gives everyday users the ability to transact privately, without needing to be online or run a server.”
Cake Wallet’s introduction of Payjoin v2 removes key usability hurdles that have long held back privacy adoption.
The protocol enables:
- Asynchronous transactions: sender and receiver don’t need to be online simultaneously
- Serverless communication: no need for either party to run a Payjoin server
- Enhanced privacy: breaks common ownership heuristics used for tracking transactions
This makes Bitcoin privacy more practical, especially for users who aren’t deeply technical. Unlike Coinjoin tools, Payjoin preserves transaction amounts while still undermining surveillance, making it ideal for merchants, mobile users, and anyone transacting in the open.
“We’ve seen huge progress with Monero privacy tools,” said Sharma. “Now, Bitcoin users can take a step towards privacy as well, built right into a mainstream wallet.”
This move comes just weeks after Cake Wallet became one of the first major mobile wallets to support Bitcoin Silent Payments, another breakthrough privacy feature.
Silent Payments allow users to receive Bitcoin without revealing a reusable address, making linking transactions to a single wallet virtually impossible.
Together, these upgrades position Cake Wallet as the most privacy-focused Bitcoin wallet available today, bringing tools once reserved for advanced users to anyone with a smartphone.
