### What is DEX?

CEX is a centralized exchange where a specific company manages all transactions. On the other hand, DEX allows users to directly supply liquidity and conduct swap transactions according to contracts published on each blockchain.

For users who are just starting out with cryptocurrency trading, deposit dollars and purchase cryptocurrency through Coinbase or Binance. However, as your trading experience increases and you want to trade more tokens or invest in DeFi products, you will need DEX trading.

As DEX fluctuates depending on the trading volume of users, price differences occur for the same token in each DEX, and sometimes there are not enough LPs and you have to pay a large premium to trade.

To solve these difficulties, Null Finance provides an **optimized swap route** so that users can trade through the optimal route without a separate search.

### What is the technical foundation?

We use solutions such as AWS, Google Cloud Platform(GCP), and Vercel to analyze multi-chain remittances and hundreds of DEXs, and we use **LayerZero** and **Hyperlane** for the most important transaction logic.

Also, in case of swap, **0x protocol** was used. 0x Protocol is a web3 service widely used around the world and is known to be used in Coinbase, Robinhood, Metamask, dYdX, etc.
