In a recent update, I announced the launch of my new hands-on course — “From Zero to One: Building a Production-Grade Dapp” — designed to share years of real-world decentralized application (Dapp) development experience in a structured, step-by-step format. This isn’t just another tutorial series; it’s a full-stack, production-ready project that will be deployed on the mainnet upon completion.
The course is now past its initial pre-sale phase and entering an advanced preparation stage. In this article, I’ll walk you through what to expect, the core features of the project, and why this is one of the most comprehensive Web3 development courses available today.
The Core Project: A On-Chain ETF Dapp
At the heart of this course lies a real-world on-chain ETF (Exchange-Traded Fund) product. While traditional ETFs track baskets of stocks or assets, our version operates entirely on the blockchain, using smart contracts to manage tokenized indices.
An ETF in this context represents a basket of crypto tokens, each with a predefined weight. Users can mint the ETF token by depositing the underlying assets in correct proportions, or redeem their ETF tokens for the corresponding basket. But we're not stopping at basic functionality.
Advanced Features Beyond Minting and Redemption
To improve user experience and scalability, the Dapp supports single-token investment and redemption. Instead of manually acquiring multiple tokens, users can invest with just ETH, USDT, or USDC. The system automatically uses Uniswap V3 to swap these into the correct weighted basket.
This introduces complex challenges:
- Calculating optimal swap paths across multiple liquidity pools
- Accurately determining input amounts based on dynamic prices
- Handling slippage and gas efficiency
We’ll tackle these with real code examples and architectural best practices.
Automated Rebalancing with Price Oracles
Over time, price fluctuations cause deviations from target weights. To maintain accuracy, the ETF requires periodic rebalancing — selling overperforming tokens and buying underperforming ones.
This process relies on:
- Chainlink price oracles for accurate off-chain data
- Automated execution via Keeper services
- Efficient multi-hop swaps using Uniswap
You'll learn two approaches to implement Keepers:
- A custom Golang-based service
- Integration with Chainlink Automation
Adding DeFi Incentives: Liquidity Mining & Staking
To encourage participation, we integrate liquidity mining, allowing users to earn project tokens by providing liquidity. This mimics yield-bearing accounts but with blockchain-native mechanics.
Additionally:
- A Uniswap V2 liquidity pool will be created for the ETF token
Users who stake their LP (Liquidity Provider) tokens can earn:
- Project tokens as rewards
- A share of protocol fees
This creates a sustainable economic model while teaching critical DeFi concepts.
Governance and Security: Multi-Sig & DAO Voting
Real-world Dapps don’t rely on single-owner control. We’ll use a multi-signature wallet to manage contract ownership securely.
Later, we transition toward decentralization by implementing:
- DAO-style voting governance
- Proposal submission and execution workflows
- On-chain decision-making using ERC20-based voting power
These modules ensure your project evolves from centralized control to community-driven operation — a hallmark of mature Web3 applications.
Frontend Integration & Full Deployment
A Dapp isn’t complete without a user-friendly interface. We’ll build a responsive frontend using popular Web3 libraries like:
- ethers.js for blockchain interaction
- wagmi for React integration
- viem for type-safe operations
Finally, we deploy every component:
- Smart contracts (with upgradeability)
- Frontend (hosted via decentralized or traditional CDN)
- Backend services (if needed)
And yes — upon course completion, participants receive a commemorative NFT certificate, minted from a custom ERC721 contract I’ve built.
Course Outline: Step-by-Step Progression
Each module builds upon the last, ensuring gradual mastery without overwhelming learners:
- ERC721 Basics: Build the course access NFT and learn standard deployment patterns.
- ERC20 Variants: Implement mock, fixed-supply, and upgradable token models.
- Token Airdrops: Explore three practical airdrop strategies with trade-offs.
- ETF v1: Core mint/redeem logic with basic basket management.
- ETF v2: Add single-token entry/exit using Uniswap V3.
- ETF v3: Integrate rebalancing powered by Chainlink oracles.
- ETF v4: Launch liquidity mining with reward distribution.
- ETF v5: Upgrade to proxy-based architecture for future-proofing.
- Staking Module: Reward LP providers via staking contracts.
- Keeper Implementation: Automate rebalancing tasks.
- Multi-Sig Management: Secure contract ownership.
- Governance System: Enable community voting.
- Deployment Finalization: Go live on mainnet.

Why This NFT Ticket Model Is Unique
Access to the course is gated by a special CourseNFT, which serves multiple purposes:
- Acts as proof of enrollment
- Grants access to private learning communities
- Can be reused for future courses at no extra cost
- Increases in value as new courses launch (price rises by 1U per sale)
Even after redemption, holders retain eligibility for future perks.
Built-In Referral Program
The NFT includes a dynamic commission system:
- Base referral reward: 5%
- Increases by 1% per successful referral (up to 50%)
- Permanent eligibility — even if the NFT is transferred
This turns early adopters into long-term affiliates, aligning incentives across the ecosystem.
Prerequisites: What You Should Know Before Starting
This is a project-focused course, not an intro to Web3. You should have foundational knowledge in:
Solidity & Smart Contracts
Recommended resources:
- WTF Academy’s Solidity 101 & 102
- Bilibili’s “Mastering Solidity 8.0” video series
Development Tools
Familiarity with at least one of:
- Remix (browser-based IDE)
- Hardhat or Foundry (advanced tooling)
I’ve covered Remix basics in my Bilibili tutorials — perfect for beginners.
Key Concepts to Understand
Before diving in, grasp:
- ERC20 and ERC721 standards
- Common tokens: WETH, USDT, USDC
- How Uniswap, Chainlink Oracles, Subgraphs, and Keepers work
All prerequisite topics are covered in my guide: “Web3 Development Unlocked” — ideal for quick onboarding.
Frequently Asked Questions (FAQ)
