# Total Value Locked (TVL)

Total value locked is the value deposited in a pool or protocol. What it measures on app.leather.io.

Total value locked (TVL) is the value of assets deposited in a pool or protocol at a given moment. A higher TVL shows that more funds are in use. It does not measure profit or safety.

On app.leather.io:

* **Staking pools ("TVL"):** the STX staked with the pool for the current cycle, summed across all of the pool's signer-manager contracts. A pool needs at least 50,000 STX staked to earn rewards for a cycle.
* **sBTC rewards providers ("Total Value Locked (TVL)"):** the value deposited with the provider, as the provider reports it. Leather does not check it.
