This module introduces blockchain concepts, Ethereum architecture, smart contracts, and decentralized application (dApp) principles. You will master installing and configuring development tools, working with the test network, and basic contract operations.
Skills you’ll gain:
- Understanding how blockchain and Ethereum work
- Using Remix, MetaMask, Ganache
- Deploying simple smart contracts on a test network

Covers Solidity syntax, contract file structure, data types, functions, access modifiers, error handling, inheritance, and working with libraries. Practice involves creating and testing your own smart contracts.
Skills you’ll gain:
- Writing correct and well-structured smart contracts
- Using inheritance, interfaces, events
- Verifying and testing contract logic

A deep dive into ERC-20, ERC-721, and ERC-1155 standards; creating and deploying your own tokens and NFTs; integrating them with dApps; improving security and gas efficiency; contract testing and validation.
Skills you’ll gain:
- Creating and configuring your own tokens and NFTs
- Integrating tokens within applications
- Ensuring token contract security

Explores common attacks, defense methods, code auditing, static analysis, multisig implementation, threat modeling, test automation, and real-case vulnerability analysis.
Skills you’ll gain:
- Auditing and testing for security
- Implementing protections against common attacks
- Applying best security development practices

Study the architecture of oracles, integration with Chainlink and other protocols, obtaining external data (e.g., exchange rates), protecting against manipulation, as well as testing and deploying oracles in dApps.
Skills you’ll gain:
- Integrating smart contracts with external data sources
- Using oracles for automation
- Ensuring reliable and secure API interaction

Covers principles of DeFi, AMM, staking, liquidity pools, cross-chain interaction, DAO, Web3 integration, interface development, testing, and optimizing complex dApps.
Skills you’ll gain:
- Building and testing DeFi protocols and dApps
- Implementing multi-currency and cross-chain solutions
- Integrating smart contracts with user interfaces

Learn methods for contract optimization in terms of gas and performance, profiling, CI/CD, DevOps, documentation, mainnet deployment, portfolio building, licensing, and career opportunities in the industry.
Skills you’ll gain:
- Optimizing and scaling smart contracts
- Automating deployment and testing
- Preparing projects for your portfolio and entering the job market
