What is TVL (total value locked)?

The total value of assets deposited in a DeFi protocol at a given moment.

TVL became the standard size measure for decentralized finance because it is the one number every protocol exposes on chain and nobody can fake by reporting it. Anyone can read the contract balances and add them up, which is more than can be said for exchange volume.

The trap is that it is a dollar figure and dollars have two moving parts. A protocol whose TVL doubled may have attracted no new deposits at all, and simply be holding the same tokens at twice the price.

How it works

An analytics provider identifies the contracts belonging to a protocol, reads the token balances those contracts hold, multiplies each by a price feed, and sums the result. That is the whole calculation, which is why different providers publish different numbers for the same protocol: they disagree about which contracts count and which prices to use.

Several practices inflate the figure without more money being present. Double counting is the big one. Deposit ETH into a liquid staking protocol, receive a staking token, and deposit that token into a lending market, and both protocols count the same underlying ETH. Chain-level and sector-level totals often add these up. Providers that adjust for it, such as DefiLlama with its double-count filters, publish both a raw and an adjusted figure.

Protocol-owned liquidity is another. Where a protocol deposits its own token into its own pools, TVL rises with the token's price on a position nobody outside the protocol contributed.

What TVL genuinely tells you is how much capital is exposed if the contracts fail, which is why it is the right denominator when thinking about risk and the wrong one for thinking about growth.

Example

Illustrative. A lending market holds 100,000 ETH and 200 million USDC. At an ETH price of $2,000 that is $200 million plus $200 million, so $400 million of TVL.

ETH rises to $3,000. Nobody deposits or withdraws anything. TVL is now $300 million plus $200 million, or $500 million, a 25 percent increase produced entirely by price. Reading that as a quarter more capital arriving would be wrong. The check is to look at the deposit balances in native token units, which did not move.

Why it matters when you buy

TVL is mostly a signal about protocols rather than about buying a coin, but it appears in the pitch for yield products people reach for after their first purchase. Treat it as a measure of how much is at stake in one codebase, not as proof of quality. Where staking is offered through an exchange instead, the yield pages show availability by venue and jurisdiction.

Questions

Why do two sites report different TVL for the same protocol?

They include different contracts, handle double counting differently, and use different price sources. Reading each provider's stated methodology explains most gaps.

Does falling TVL mean people are leaving?

Not necessarily. Falling token prices reduce it mechanically. Compare balances denominated in the underlying tokens over the same period to separate outflows from price moves.

Is TVL relevant to buying a coin on an exchange?

Only indirectly. It describes deposits in a protocol, not demand for a token, and a governance token's price and its protocol's TVL can move in opposite directions for long stretches.
