Keet is built on top of Holepunch, using DHT and holepunching to connect nodes without intermediaries.
Wallet Development Kit was already open-source and now the complete communication layer is added.
Tether, through its CEO Paolo Ardoino, announced the complete opening of the code of its messaging and video calling application Keet during the Bitcoin 2026 conference, held on April 29, 2026. The movement is part of a broader strategy of building digital infrastructure resistant to central dependencies, under the concept of “Resilience Stack”.
During the presentation, Ardoino made a historical reading of digital communication like a system that has passed from models peer-to-peer to structures intermediated by large platforms. Under that premisethe opening of Keet is proposed as a return to a model of direct communication between userswhere the software is open and extensible from its base.
It is worth noting that Keet does not start from a closed architecture. The application was already built on open components developed by Holepunch and the Pear Runtime, which enable direct communication between devices using distributed node discovery (DHT) and holepunching techniques to traverse NAT and firewalls without central servers.
The novelty of the announcement lies in the fact that now the entire application is releasedincluding its internal logic and its interface layer, which until now were not completely open source. This step completes a stack where other components had already been previously opened, such as the Wallet Development Kit —released months ago for the development of self-custody solutions— and QVAC, aimed at the local execution of artificial intelligence models, as reported by CriptoNoticias.
At the operational level, Keet also operates without intermediate servers: devices connect directly to each other and data circulates through end-to-end encrypted channels. This model shifts traditional infrastructure functions to the user network itself.reducing dependence on backend centralized.
With the complete openness of the code, the Holepunch ecosystem now has a completely auditable and modifiable communication layer. The result is an architecture where messaging, application development, and service execution can operate over P2P infrastructure without central intermediaries.
