Who this is for — Anyone valuing DeFi and L2 protocols: TVL measures capital «locked» in contracts — proxy for trust and usage, cross-check with fees and tokenomics.
TVL (Total Value Locked) is the USD (or ETH) value of assets deposited in a DeFi protocol — lending, DEX liquidity, staking, restaking — sum of user positions in smart contracts.
In plain terms — «How much money is in the protocol right now» — popularity and depth, not automatic profit.
What it signals
| Reading | Interpretation |
|---|---|
| TVL ↑ | Adoption, incentives, narrative |
| TVL ↓ | Outflows, hack fear, better yield elsewhere |
| TVL / token market cap | Narrative leverage on token |
| TVL per chain | Ecosystem dominance |
Protocol revenue = fees × volume, not TVL directly. Two protocols with same TVL can have opposite economics.
Limits
- Double counting cross-protocol (wrap, recursive deposit)
- Mercenary incentives (farming) inflate TVL temporarily
- Does not replace security audits and token supply
- Bridge TVL fragile on cross-chain exploits
Common mistake — Buying token only because TVL rises — without real fees and emission dilution.
Example — DEX A TVL $2B, 0.05% fee on $5B/month volume → meaningful revenue; Lending B TVL $2B but low borrow → weak revenue.
