About aXedras™

The vision for a connected and digitalized precious metal solution started taking shape in 2017 and was translated into a successful proof of concept a few months later. aXedras Ltd was incorporated in 2018 as an independent technology company and is headquartered in Switzerland - an international hub for blockchain and DLT solution providers.


Moreover, aXedras Ltd collaborates regularly with:


  • National authorities to shape and evolve the legal framework for distributed ledger technology in Switzerland and globally

  • Market associations to develop an approved software solution for bullion integrity on
    a global scale

  • Key stakeholders of the bullion market as well as innovative technology providers

​The name 'aXedras' is derived from the English word 'access' and the Greek word 'exedra', meaning platform.
