The DeFi landscape continues to evolve with blockchain ecosystems competing for dominance through innovative applications and strategic partnerships. Total Value Locked (TVL) is one of the key metrics to measure the health and attractiveness of these ecosystems. In this article, we have compiled a list of the top 10 blockchains in March 2026 by TVL growth, with a minimum Range of $10 million, using data from DefiLlama, a leading DeFi analytics platform. 

What is TVL?

Total Value Locked (TVL) is a key metric in the decentralized finance (DeFi) ecosystem that represents the total U.S. dollar value of digital assets that are currently locked in DeFi platforms. These assets can include cryptocurrencies, stablecoins, liquidity tokens, and other digital assets used for various purposes such as staking, liquidity provision, and yield farming. It serves as an indicator of a DeFi platform's health and popularity, reflecting user trust and engagement.
