DefiLlama is widely recognized as the most transparent and comprehensive decentralized finance (DeFi) data aggregator in the industry. It is fully open-source and does not issue any tokens, maintaining a high degree of neutrality. Unlike CoinGecko, which focuses on token prices, DefiLlama's core function is tracking TVL (Total Value Locked). Through it, users can intuitively view capital inflows and outflows across various blockchains and protocols, thereby assessing the true activity and health of the ecosystem. Beyond TVL, it also offers features such as stablecoin market cap, yield comparisons, and protocol revenue analysis, making it an essential dashboard for researching DeFi fundamentals.
