Deep Dive into leading Ecosystems
You may have heard of Binance and FTX from the news headlines. They are called Centralized Exchanges (CEX) since one company operates them and reaps profit from operating them. What is a Decentralized Exchange (DEX)? A decentralized exchange (DEX) is a peer-to-peer marketplace where users can trade cryptocurrency directly with each other, without using an intermediary. Popular DEXs include Uniswap, SushiSwap, Pancake Swap, DODO, and Curve. In Part 1 of the DEX course, we will learn to build a liquidity pool and implement the “add liquidity” functionality.
什么是稳定币？稳定币是旨在保持稳定价值的加密货币，通常与法定货币、交易所交易商品或另一种加密货币等参考资产挂钩。 DAI 是一种运行在以太坊区块链上的去中心化稳定币，试图维持 1 美元的价值。 在 DAI 课程中，我们将首先学习构建稳定币合约，包括存款和提取抵押品功能。其次，我们将继续构建稳定币合约，重点关注铸币和销毁功能。之后，我们将通过解释 DeFi 背景下的清算如何运作来结束稳定币系列。在这一系列课程之后，我们将挑战您构建一个比 DAI 更好的稳定币！
In Part 3 of the DAI course, we will wrap up the stablecoin series with an explanation of how liquidation works in the DeFi context. After this series of lessons, we challenge you to build an even better stablecoin than DAI!
In Part 2 of the DAI course, we will continue to build the StableCoin contract, focusing on the mint and burn functions.
What are Stablecoins? Stablecoins are cryptocurrencies designed to maintain a stable value, typically pegged to a reference asset such as fiat money, exchange-traded commodities, and another cryptocurrency. DAI is a decentralized stablecoin running on the Ethereum blockchain that attempts to maintain a value of 1 USD. In Part 1 of the DAI course, we will learn to build a StableCoin contract including the deposit and withdraw collateral functions.

什么是 NFT？NFT 是存储在区块链上的独特数字资产，代表艺术品、音乐或收藏品等独特物品的所有权。在 NFT 课程中，我们将首先学习 NFT 合约的初级基础知识，包括铸造 NFT、按 tokenId 查询 NFT 和按所有者查询代币。之后，我们将学习如何执行 NFT 合同中更多的三项功能，以支持 NFT 的转移和刻录。
In Part 2 of the NFT course, we will learn to implement more three functions of our NFT contract, that support transferring and burning of NFTs.
What is an NFT? NFTs are unique digital assets stored on the blockchain, representing ownership of distinct items such as art, music, or collectibles. In Part 1 of the NFT course, we will learn the fundamentals of NFT contracts at a beginner-friendly level, including minting NFTs, querying NFTs by tokenId, and querying tokens by owner.
什么是代币？你有没有想过发行自己的代币？同质化代币（ Fungible Token，简写为 FT）是可以一对一互换的数字资产，代表统一的价值单位。在同质化代币课程中，您将在一小时内学会铸造自己的同质化代币、检查余额和执行无缝转账的基本步骤。
What is a token? Ever thought about launching your own token? Fungible tokens are digital assets that are interchangeable on a one-to-one basis, representing a uniform unit of value. In the Fungible Token (FT) course, you'll learn the essential steps to mint your own fungible token, check balances, and execute seamless transfers in under an hour.
