# Web3 Aggregator SDK aka Kana Crosschain SDK

This SDK is a toolkit that sits on top of a multi-chain-focused foundational layer and is made of three components -multiple liquidity sources (DEXs & Liquidity Aggregators), a bridge and messaging protocol aggregator and a smart routing algorithm.

The foundational layer consists of 9 different chains from both EVM and non-EVM blockchains. By combining all these components into one unit, we offer an easy-to-use plug-and-play-type SDK that enables a product to instantly gain industry-leading Web3 transaction capabilities.
