Build Protocols from Scratch
Before you fork a protocol, you need to understand every line of it. What you have available, what you'll want to use, and what you'll want to change. Building it yourself, guided, is the only way to get there.
The Fork Problem
Most DeFi builders start by forking a protocol. They clone Uniswap V2, change the fee, swap the logo, and deploy. But they don't understand why the constant product formula uses 997/1000. They don't know why the minimum liquidity exists. They can't modify the core without breaking invariants they never knew existed.
Fork and hope
- xClone repo, change branding
- xNo idea what half the code does
- xModify one function, break three others
- xDeploy with hidden vulnerabilities
Build and understand
- +Write every function yourself
- +Understand every design decision
- +Know which parts to keep, change, or remove
- +Deploy with confidence
How It Works
Pick a production protocol
Each module is a real protocol. Uniswap V2 is live now. Uniswap V3 and Compound V2 are coming. You pick which architecture you want to master.
Read the theory, then write the code
Learn sections explain the concepts and architecture. Build sections give you starter code with TODO blocks. You figure out the logic. No copy-paste. Hints guide you, but the thinking is yours.
Pass automated tests
Every section has tests that verify your implementation. Did you apply the 0.3% fee correctly? Is the reentrancy guard in place? Does your mint function use the sqrt formula? Instant feedback.
Walk away with a complete protocol
When all tests pass, you have a multi-contract system you built and deeply understand. Factory, Pair, Router, Library. All connected. All yours. Deploy to testnet, modify for your project, or move on to the Shadow Arena.
