# Messaging Layer

Messina.one uses Wormhole as it's primary messaging layer across different chains for bridging. As such, we are utilising Wormhole's infrastructure like their Guardians, their messaging format and their VAA format.&#x20;

Messina.one also utilises a secondary messaging layer which is forked from Wormhole for chains that are not currently supported by Wormhole e.g. Cronos.&#x20;
