Module 3: Smart Contracts
Did not Read Part 1?
3.1 Introduction to Smart Contracts:
Smart contracts are self-executing contracts with the terms of the agreement directly written into code. They automate and enforce the execution of contractual clauses, removing the need for intermediaries.
3.2 Significance in Web3:
Smart contracts play a pivotal role in the Web3 ecosystem by enabling trustless and decentralized agreements. They are the building blocks of decentralized applications (DApps) and contribute to the programmability of blockchain.
3.3 Solidity Programming Language:
Solidity is the most widely used programming language for developing smart contracts on the Ethereum blockchain. Understanding its syntax, data types, and control structures is essential for smart contract development.
3.4 Anatomy of a Smart Contract:
Explore the key components of a smart contract, including state variables, functions, and events. Understand how these elements interact within the contract and contribute to its functionality.
3.5 Writing and Deploying a Simple Smart Contract:
Participants will engage in a practical exercise to write and deploy a basic smart contract. This hands-on activity reinforces the understanding of Solidity and the deployment process.
3.6 Interacting with Smart Contracts:
Learn how users and other contracts interact with deployed smart contracts. Discuss the role of transactions, gas fees, and the execution of functions through various interfaces.
3.7 Security Best Practices:
Security is paramount in smart contract development. Explore common vulnerabilities such as reentrancy attacks, integer overflow, and malicious inputs. Learn best practices to mitigate these risks.
3.8 Upgradability and Maintenance:
Smart contracts need to evolve over time. Explore strategies for making contracts upgradable while maintaining security. Understand the challenges and considerations in upgrading deployed contracts.
3.9 Decentralized Finance (DeFi) and Smart Contracts:
Delve into the role of smart contracts in decentralized finance (DeFi) applications. Explore use cases such as lending, borrowing, and automated market makers (AMMs) facilitated by smart contracts.
3.10 Oracle Integration in Smart Contracts:
Understand the importance of oracles in providing external data to smart contracts. Explore how oracles enhance the capabilities of smart contracts by allowing them to interact with real-world information.
3.11 Practical Exercise: Developing a DeFi Smart Contract:
Participants will undertake a hands-on project to develop a basic decentralized finance (DeFi) smart contract. This exercise combines concepts learned, emphasizing real-world applications.
3.12 Assignment: Security Audit of a Smart Contract:
Students will conduct a security audit of a provided smart contract, identifying potential vulnerabilities and proposing solutions. This assignment enhances practical understanding and security awareness.
This module immerses participants in the world of smart contracts, providing both theoretical knowledge and practical skills essential for Web3 development.
