# 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. 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. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
