Total value locked, the dollar value of assets held in a protocol.
TVL is the headline metric for DeFi size. It counts everything deposited in a protocol's contracts, valued in dollars.
Treat it carefully. TVL rises when token prices rise even if no new deposits arrive, and double counting is common when assets are looped between protocols.
DefiLlama tracks TVL across chains and protocols and is the standard reference.
That high TVL means a protocol is trusted. It can be one whale, mercenary capital chasing an incentive that ends next month, or the same deposit counted at several layers. Watch what happens to TVL when the rewards stop.
Common questions
Is high TVL a sign a protocol is safe?

Some of these land faster in conversation than in writing. Sessions are one to one and you can ask anything, including the things that feel too obvious to ask.
