Introduction to Decentralized Lending

When I first started exploring decentralized lending protocols, I realized that most documentation focuses on the basics, skipping over the hard parts. Last quarter, our team discovered that building a scalable decentralized lending protocol requires more than just understanding the technology - it demands a deep dive into smart contract development, yield optimization, and the intricacies of blockchain ecosystems.

The Problem with Traditional Lending Protocols

Traditional lending protocols often suffer from scalability issues, high transaction fees, and lack of transparency. We tried to build our protocol on Ethereum, but the gas fees were astronomical, and the network congestion was unbearable. That's when we decided to explore Polygon, a layer 2 scaling solution that promised faster transaction times and lower fees.
