Nexus Mutual is a platform which aims to provide users with a transparent, cheaper and accessible protection against financial risks. In another sense, the platform functions as an insurance firm. Most of the financial risks involved in Nexus Mutual are smart contracts failures, though smart contract failures aren't very common nexus Mutual seeks to prevent and protect users from the risks.
The exchange has its own token, NXM which can only be used by the members of this platform hence it cannot be used on any other exchange. The exchange doesn't have a high trading volume nor enough social media presence, hence users should still make their extra research before making any form deposit on the platform.
