TVL
TVL (total value locked) is the total dollar value of crypto deposited in a DeFi protocol or network. It shows how much money users have entrusted to its smart contracts.
How it works
TVL adds up everything sitting in the contracts: liquidity pools, collateral in lending protocols, staked assets. People use it to compare the size of protocols and chains and to see where money in DeFi is flowing.
TVL is measured in dollars, so it depends heavily on prices. If ETH halves, TVL nearly halves too, even if nobody withdraws. The same money can also be counted several times: ETH is staked, the LST is posted as collateral, the loan goes into a pool.
High TVL signals trust and liquidity, not safety or protocol revenue. It can be inflated by temporary rewards that run out, after which the money leaves. It is more useful alongside trading volume, fees and revenue.
A protocol holds 1,000 ETH at $3,000 plus 3,000,000 USDC, so TVL is $6 million. ETH falls to $1,500, nobody withdraws, yet TVL becomes $4.5 million, down 25% from price alone.
A common mistake is assuming a protocol with big TVL is safe, or that rising TVL means its token will go up. Large protocols have been hacked too, and TVL can rise on rewards nobody holds for long. Look at audits, track record and what the TVL is made of.
Questions and answers
What is TVL in simple terms?
It is how much money is sitting in a DeFi protocol right now, counted in dollars at current token prices.
Why does TVL drop when nobody withdraws?
Because TVL is counted in dollars. When the tokens in the protocol fall in price, TVL falls with them.
Does high TVL mean a protocol is safe?
No. It measures size and trust, not security. Protocols with billions in TVL have been hacked.
