Welcome to the course on Decentralized Finance (DeFi) Protocols! In this course, we will explore the exciting and rapidly evolving world of DeFi, where traditional financial services are being reimagined and decentralized using blockchain technology. Whether you're a blockchain enthusiast, a financial professional, or just curious about the future of finance, this course will provide you with valuable insights into DeFi protocols.

Decentralized Finance, often abbreviated as DeFi, is a revolutionary and rapidly growing sector within the blockchain and cryptocurrency space. It represents a fundamental shift in how financial services are designed, accessed, and executed. Unlike traditional financial systems, DeFi aims to create an open and permissionless financial ecosystem that is accessible to anyone with an internet connection.

Uniswap Version 1 (Uniswap V1) was the first iteration of the popular decentralized exchange (DEX) protocol called Uniswap. It was launched in November 2018 by Hayden Adams and gained significant attention within the decentralized finance (DeFi) space for its innovative approach to automated token swaps and liquidity provision.

Uniswap V3 is the most powerful version of the protocol yet, with Concentrated Liquidity offering unprecedented capital efficiency for liquidity providers, better execution for traders, and superior infrastructure at the heart of decentralized finance.

The easiest way to safely add liquidity to a pool is to use the router, which provides simple methods to safely add liquidity to a pool. If the liquidity is to be added to an ERC-20/ERC-20 pair, use add liquidity. If WETH is involved, use add LiquidityETH.
