Overview of this book

Enter the world of Decentralized Finance (DeFi) with Building Full Stack DeFi Applications. Understand how this blockchain-based financial technology, designed to manage crypto assets, runs independently without centralized financial institutions like banks and brokerages, eliminating the fees that banks and other financial companies charge for using their services. This book will show you how DeFi solutions are built with smart contracts running on blockchains and how they allow users to gain and earn crypto assets based on the trust of the smart contracts. This book uncovers the inner workings of DeFi by guiding you through the mathematical foundations and teaching you how to build real-world DeFi products with Solidity and JavaScript. As you progress through the chapters, you’ll learn how to implement smart contracts of liquidity pools to trade cryptocurrencies and implement staking, including farming features that allow users to earn. You’ll also find out how to create asset pools that allow users to lend and borrow cryptocurrencies and generate interest. Additionally, you’ll discover how to use Web3 libraries to build the frontend of DeFi products. By the end of this book, you’ll will be well acquainted with popular tools, libraries, and design patterns for implementing a full-stack DeFi application with Web3 and Solidity.

Deploying smart contract metadata to the frontend

Before interacting with smart contracts, we need to make the smart contract metadata accessible to the frontend. Smart contract metadata is the required information for frontend code to access a smart contract on the blockchain. To be more specific, it refers to the smart contract ABI and the smart contract address that is deployed on the blockchain.

The smart contract ABI is a section of code for off-chain components to communicate and interact with the smart contract code deployed on the blockchain. It defines the interfaces that off-chain components can use to access the smart contract, including its functions, variables, and events. Usually, the ABI used by decentralized application frontend code is in the form of JavaScript Object Notation (JSON). Meanwhile, the DeFi application also requires you to know the smart contract address so the frontend code can locate the smart contract to interact with.
