In 2018, Uniswap's x * y = k formula democratized market making. Today, Solana's high-performance blockchain (400ms finality, sub-cent fees) enables solo developers to build sophisticated automated liquidity provision businesses that were once the domain of Wall Street firms. This technical deep-dive explores how developers can leverage Solana's DeFi protocols (Raydium, Jupiter, Kamino) to create passive income streams through automated market making, concentrated liquidity positions, and cross-protocol optimization. The article covers protocol integration, strategy components, and risk management frameworks for building profitable, automated DeFi systems. Discussion welcomed on the intersection of algorithmic trading, DeFi composability, and solo developer opportunities in the new financial paradigm.
