Defi Protocol Templates

This gives you production-ready Solidity contracts for common DeFi primitives: staking with reward distribution, a constant product AMM with liquidity pools, governance tokens, and lending protocols. The templates use OpenZeppelin for security basics like reentrancy guards and include the math you'd expect (reward per token calculations, liquidity share formulas, swap pricing with 0.3% fees). It's solid scaffolding if you're prototyping a DeFi protocol or learning how these mechanisms work under the hood. The code is clean but simplified, so you'll want to add proper access controls, emergency pauses, and thorough testing before putting real money on it. Saves you from writing the constant product formula from scratch for the hundredth time.
