The Vibe: The total amount of real crypto money people have put into a DeFi project or chain—like checking how much cash is sitting in a bank’s vault to see how popular and trusted it is.
The Details: TVL (Total Value Locked) is a key number in DeFi that shows the dollar value of all assets users have deposited or locked in a protocol’s smart contracts. It includes money in liquidity pools, lending platforms, staking, or yield farming. Higher TVL usually means more users trust the project, more liquidity for trading, and potentially better rewards. It’s calculated by adding up the current market prices of all locked tokens. Trackers like DefiLlama or CoinGecko show TVL for individual protocols or entire chains (e.g., Ethereum, Solana).
Pro Tip: Check TVL on sites like DefiLlama before using a DeFi app—higher TVL with steady growth is a good sign of trust and liquidity. Compare TVL to the project’s age and features; very high TVL in a new project can sometimes be risky (watch for manipulation).
