This course is structured into five sections:
Introduction
Environment Setup
Solidity (Understanding the language)
Advance (Build a Payable smart contract and UI)
Finally Build a Defi app
Ethereum is the community-run technology powering the cryptocurrency, ether (ETH), and thousands of decentralized applications.

Explore implicit and explicit type conversion in Solidity, showing how the compiler performs implicit conversions in assignments and operators, and why explicit conversions help avoid information loss and unexpected results.
Learn how function modifiers in Solidity enforce access control and pre/post conditions, demonstrating input validation and guarded operations to prevent unauthorized withdrawals and duplicate calls.
Define and leverage interfaces and abstract contracts to standardize smart contract interactions; implement or override functions, and call methods by passing contract addresses and function signatures.
Learn how to handle errors from external calls in Solidity using try and catch, including how call, delegatecall, and staticcall influence error propagation and recovery.
Compare sending ether from smart contracts using transfer, send, and the low-level call.value. Understand gas considerations, typical use cases, and safety notes like using modifiers to guard against risky calls.
Explore Solidity libraries, embedded versus deployed patterns, and linking libraries to contracts to prevent overflow and underflow in unsigned integers using a popular library's safe math.
Learn how to link a deployed Solidity library instead of embedding and redeploying, by copying its address into your contract and deploying against the deployed library on the correct network.
Explore the relationship between wei and ether in Solidity, learn why 1 ether equals 10^18 wei, and understand using the smallest unit to avoid decimals in smart contracts.
Compile and deploy smart contracts to a Ganache network using Truffle, configure a workspace, generate addresses, and migrate contracts with migration flows.
Connect to the rinkeby test network via Infura, configure a provider with mnemonic, deploy smart contracts through migrations, and verify the deployed contract on the network.
Learn to build a Bootstrap-based UI that uses ethers.js to deploy and interact with Ethereum smart contracts, including deposits, withdrawals, and ownership transfers, with wallet interactions and events.
Learn how upgradeable smart contracts work using proxy patterns and OpenZeppelin libraries, including proxy and implementation contracts, initialize patterns, and storage safety.
Redeploy a version 1 payable smart contract to Ganache by setting up dependencies, initializing contracts, and performing migrations, while managing gas, imports, and proxy deployments.
What problem are we solving by building this Defi Smart Contract
This course is a practical guide on how to become a blockchain developer.
You will learn and understand every syntax of Solidity in Depth. You will also learn how to use Ethereum development tools such as Truffle, Remix, Ganache CLI & Client, Metamask, EthersJS, Infura, and many others to aid you in your Development journey.
You will be building two real-life example projects, both Defi applications, and deploy them on both the Binance Smart Chain and Ethereum networks. You will also get to build a UI for one of the Defi Smart contracts to integrate and interact with it from your browser using Metamask or Trust Wallet.
By the end of this course, I guarantee you that you will have acquired enough knowledge to apply for a Solidity developer role. You will find that you will become confident to take on any ethereum or Binance Smart Chain project, provided you can complete this course and put in the extra work required.
I will be updating this course regularly to not only keep up with breaking changes in Solidity. I will be adding more course content to cover various topics from student feedback, and what I know would help anyone taking this course build more real-life applications using Solidity.
