What Is Total Value Locked?
Total Value Locked (TVL) measures the aggregate dollar value of all assets deposited into a DeFi protocol's smart contracts. It includes liquidity pool deposits, staked tokens, collateral in lending protocols, and any other assets under the protocol's management. TVL is the most widely used metric for comparing DeFi protocols' adoption and trust.
How Total Value Locked Works
TVL is tracked by DeFi aggregators and is typically measured in real-time. It fluctuates based on: new deposits/withdrawals, price changes of deposited assets (if ETH drops 20%, ETH-denominated TVL drops proportionally), and the addition of new chains or pools. Some protocols inflate TVL through recursive deposits or double-counting across chains.
Why It Matters for Traders
While TVL is useful for comparing protocol adoption, it has limitations as a valuation metric. TVL can be temporarily inflated by unsustainable incentives (high APY attracts mercenary capital that leaves when rewards end). Revenue per TVL is a better measure — it shows how efficiently the protocol converts locked capital into actual fees. A protocol with $1B TVL and $100M annual revenue is more valuable than one with $5B TVL and $50M revenue.
