# LayerZero The [LayerZero](https://twitter.com/LayerZero_Labs) messaging layer (*omnichain interoperability*) gives Archimedes the tools needed to access and farm across 70+ blockchains.

LayerZero enables the realization of cross-chain applications with a low level communication primitive. At the core of this technology are Ultra Light Nodes (ULNs). ULNs allow decentralized exchanges (DEXs) such as SushiSwap to *‘have one single interface and code base for all cross-chain pairs.’* --- # 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.
