About us


Vulpem is a technology R&D lab focused on Bitcoin security and trust-minimized application development. We are the creators of Nigiri CLI, Marina Wallet and Liquid Taxi. We are the maintainers of Go Elements and contributors of LiquidJS

Who & Why

A distributed team of software engineers and technologists passionate about self sovereignty, privacy and operational security. We work both for internal funded projects and for clients, we do our best to attract and land only Bitcoin projects.


We don't focus on a single programming language or stack, we use the best tool to accomplish the goals.

A typical internal project would start with an internal press release to make clear the product vision to all team members like AWS does, then an appointed product manager develops a prototype and writes down the design rationale. If we get business approval or market traction, we develop the product with the necessary engineers and the right stack.

We mostly write programs in Go, Python, JavaScript, Rust or C. We pack the apps and services with Docker and mostly deploy on AWS if cloud is allowed or ARM-based infrastructure owned by Vulpem. We publish our web services under an Onion hidden service.


Full remote. No offices. We strive to do an annual gathering of a week once a year across Europe, with no work related duties, focusing only on wellness activities, mindfulness sessions and team building.


People in Vulpem have possibility to work both with a regular full position and to work with an extremely distributed software development methodology
