TVL

In Brief
TVL (Total Value Locked) is a key DeFi metric that measures the total value of crypto assets deposited in a protocol — used to gauge its size, adoption, and overall health.
What Is TVL (Total Value Locked)?
TVL, or Total Value Locked, is the total value of all crypto assets deposited in a DeFi protocol at a given moment. It includes funds staked, lent, or supplied to liquidity pools, and is usually expressed in US dollars.
TVL is one of the most widely used metrics in DeFi because it offers a quick snapshot of how much capital a protocol — or the DeFi ecosystem as a whole — has attracted. Generally, a higher TVL signals greater trust, usage, and liquidity.
How Is TVL Calculated?
Add up all the tokens deposited in the protocol (in lending pools, liquidity pools, staking contracts, etc.).
Multiply each token's amount by its current market price.
Sum these values to get the total, typically denominated in USD.
Because it depends on token prices, TVL can rise or fall sharply even if no deposits or withdrawals occur — simply because the value of the underlying assets changes.
Why Does TVL Matter?
| Use | What It Tells You |
|---|---|
| Protocol size | How much capital a protocol manages |
| Adoption trend | Whether users are depositing or withdrawing over time |
| Comparison | How protocols and chains rank against each other |
| Liquidity health | Deeper liquidity generally means lower slippage |
Limitations of TVL
Price-driven swings — TVL can jump or drop purely from token price changes, not real adoption.
Double counting — assets reused across protocols (e.g. staked then re-deposited) can be counted more than once.
Token incentives — high TVL can be temporarily inflated by reward programs that attract "mercenary" capital.
Not a safety guarantee — a high TVL doesn't mean a protocol is secure or audited.
TVL of a Protocol vs a Chain
TVL can be measured for a single protocol (how much is locked in one app) or for an entire blockchain (the sum across all of its DeFi protocols). Comparing chain-level TVL is a common way to gauge which ecosystems are attracting the most DeFi activity.
TVL and Trust Wallet
When exploring DeFi through Trust Wallet's dApp browser, TVL is a useful first signal of a protocol's scale and liquidity. Trust Wallet lets you connect to DeFi protocols across 100+ blockchains while keeping full control of your private keys — so you can research, deposit, and withdraw on your own terms as a non-custodial user.
