Summary

In this chapter, we have gone through the process and explained the code for implementing liquidity management features for a DEX. We learned about the workflows of typical liquidity management operations such as liquidity information retrieval, liquidity provisioning, and liquidity removal. For each of these operations, we learned about and discussed the code implementation with Web3 technologies. We showed you how to use ethers.js to interact with the smart contracts implemented in Chapter 5, Building Crypto-Trading Smart Contracts to complete these operations. We also demonstrated other topics such as creating sub-routes in React.js and verification of the liquidity management features in this chapter.

In the next chapter, we will proceed with the journey of implementing the frontend of the most important feature of a DEX: swapping. This feature will allow users to swap tokens with other tokens using the DeFi application in web browsers.
