# LayerZero

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).&#x20;

ULNs allow decentralized exchanges (DEXs) such as SushiSwap to *‘have one single interface and code base for all cross-chain pairs.’*
