Overview
DefiLlama is a free analytics tool that tracks and compares the total value locked (TVL) across decentralized finance protocols and blockchains. It provides transparent, community-driven data to help users explore the DeFi landscape. DefiLlama became the standard source for TVL data because it relies on contributors and open methodology rather than a commercial team.
How It Works
DefiLlama's community of contributors maintains adapters that read on-chain balances from each protocol and compute its TVL in a consistent way. The platform aggregates these numbers into dashboards that rank protocols, chains, and categories, and it also tracks yields and stablecoins. Because the data is derived from on-chain state, it is independently verifiable.
Why It Matters
DefiLlama's independence made it the most trusted source for comparing protocol size and market share, and its data is cited throughout the industry. It also exposed how TVL can be misleading when double-counted or inflated, encouraging more careful analysis. Its community model set a precedent for open, contributor-maintained analytics.
