• Website: Web3.js

• Description: A lightweight and complete library for interacting with the Ethereum blockchain and its ecosystem.
• Key Features:
• Smaller and more modular than Web3.js.
• Easy-to-use API for interacting with contracts and wallets.
• Extensive support for signing transactions and handling wallets.
• Built-in utilities for interacting with Ethereum Name Service (ENS).

• Website: Ethers.js

Once your contract is deployed, you can interact with it using Hardhat or a front-end interface.

• Open the Hardhat console:

• public: Accessible externally and internally

• internal: Accessible only within the contract and derived contracts

1. Uniswap

• Optimization: Uniswap V2 introduced several optimizations, including reducing the number of state changes in core functions and using assembly code for certain operations.
• Impact: These optimizations led to significant gas savings, making Uniswap more cost-effective for users.
