About Us



Arkonis facilitates institutional agency crossing of of multiple asset classes and in multiple markets. The state of the art electronic platform can be accessed via EMS and OMS providers or through direct FIX connections.

Arkonis simplifies liquidity discovery by connecting natural counterparties from around the globe anonymously and efficiently without the worry of leakage.

It is designed with a view to reducing market impact and lowering direct and indirect trading cost, enabling participants to effectively uncover hidden liquidity for their orders and to eliminate spreads.


Arkonis is connected to difficult to reach liquidity providers in multiple assets and especially in Crypto Currencies. In order to provide this allows sell side firms to use these feeds to reprice non strategic assets and active buy side to reach directly the liquidity sources. It also allows the Buy Side to publish their interest  to the public they select.
