New Bitcoin Wallet Turns WhatsApp into Crypto Payment Tool

Bitcoin transactions are now possible directly through WhatsApp, thanks to a new tool called Sati, developed by founder Felipe Servin. The wallet, which operates entirely within the messaging app, allows users to send and receive Bitcoin without downloading any additional software.

Sati is a non-custodial wallet, meaning users retain full control of their funds, and private keys are never stored by the service. To get started, users simply message the Sati bot on WhatsApp, set a PIN, and the system links it to a unique identifier from their device. All wallet data is securely stored on the user’s phone, ensuring that only the owner has access.

The innovation is targeted at regions where WhatsApp is a primary means of communication and where financial infrastructure is often limited.

Servin highlighted areas like Mexico, Brazil, Türkiye, and several African countries, noting that residents frequently face challenges such as limited access to traditional banking, currency devaluation, and difficulty obtaining U.S. dollars. Bitcoin, he said, offers a viable alternative for saving and transferring money.

Looking ahead, Sati aims to support stablecoin swaps through the Lightning Network, making it easier for users to convert digital dollars into Bitcoin. The team is also working on secure wallet recovery options to help users who lose access to their devices.

Servin emphasised that early feedback from users has been highly encouraging, particularly from those in economically unstable regions who now have a simple way to make financial transactions via chat.
