Ethereum Blockchain Developer Bootcamp With Solidity (2025)

Explore Remix file management, workspaces, and file creation in a Solidity development environment with an integrated compiler, artifacts folder, JavaScript runtime, and a plugin architecture for testing and deployment.

Explore the three Solidity function types—writing, view, and pure—through practical examples, storage variables, getters, and how gas and return values differ in practice.

Wraps up Solidity variable types including booleans, integers, addresses, strings, and memory vs storage, notes default values, public getters, and fixed point concepts, plus 18-decimal ERC-20 tokens and wei-ether basics.

Decode Ethereum transactions by examining the transaction object, from and to addresses, value in wei, gas, data, and nonce. Learn how Metamask signs transactions with a private key.

Install MetaMask and connect to a website to inject a web3 provider, explore networks with free ether, and begin building a full wallet solution; share code on GitHub.

Learn to combine mappings and structs in Solidity to track deposits and withdrawals, record transactions with timestamps, and manage balances with a nested balance struct.

Build a smart contract wallet that receives funds, allows controlled transfers and allowances, and enables owner recovery via three-of-five guardians with proposals and guardian votes.

Create a simple coin and smart contract with a token sale, using 0.1 ETH, while examining transfer, balanceOf, allowance, block explorers, source code verification, and standardized interfaces for DeFi.

Explore deploying and interacting with smart contracts using web3.js, including fetching accounts, viewing balances via metamask and remix, and subscribing to contract events.

Learn how to use events to communicate with the outside world by emitting logs when token transfers occur, and observe logs in remix and metamask.

Implement an erc20 token sale by giving the sale contract allowance to spend tokens, transferring tokens for ether at a fixed price, and returning any remainder.

Publish your token sale progress by posting your code to Etherscan and GitHub, and share on LinkedIn; then develop an NFT using an audited Open Zeppelin template for ERC 721.

Install the essential prerequisites for truffle and foundry across Windows, Linux, or Mac, including node, npm, and git, then set up VS Code with solidity extensions and Ubuntu via WSL.

install and initialize truffle globally inside a main folder with hardhat and foundry projects. scaffold a truffle project with contracts, migrations, and tests, and review its build artifacts and config.

Learn how to create and run Truffle migrations to deploy smart contracts using deployer and artifacts, interact with a local Ganache blockchain, and configure networks for deployment.

Learn to write your first Truffle unit test in JavaScript, deploy contracts, and master advanced event assertions with shuffle assertions for transfer logs.

Build and test your own NFT with offline unit tests across free frameworks and deploy scripts. Explore Foundry and Truffle templates and push a polished GitHub readme to impress HR.
