# Use Idle Liquidity

A51 Carbon has a feature that allows pools to earn additional yield by depositing idle assets into external protocols. This mechanism maximizes the efficiency of capital within the pool and increases returns for liquidity providers (LPs).

Any external protocol can be used where liquidity can be brought back to A51 if liquidity becomes active again and the current price is in the position range.

This feature can be used in conjunction with JIT (Just-in-time) mode in Market Shift intent where liquidity is earning yield in any external protocol most of the time like AAVE, but is brought to A51 when the range becomes active. In JIT, liquidity is provided in an extremely narrow range, usually a single tick.
