Protocol-owned liquidity (POL)
Protocol-owned liquidity (POL) is DEX liquidity that a protocol holds in its own treasury instead of renting it from outside providers with token rewards.
Most DeFi projects attract liquidity by paying token emissions to outside providers, who often leave as soon as the rewards fall. With protocol-owned liquidity, the treasury itself holds LP positions in the pools that matter for its token, so the market depth stays in place regardless of what mercenary capital does. The positions are usually acquired by selling bonds, swapping treasury assets or keeping part of the trading fees.
The idea became popular in 2021 with OlympusDAO, which sold its token at a discount in exchange for LP tokens, and spread to many DAOs and DEX designs. A protocol that owns its liquidity also earns the trading fees those positions generate, turning a cost into a source of revenue.
POL is not free. The treasury bears impermanent loss and smart-contract risk on the pools, and capital locked as liquidity cannot be spent elsewhere. If the paired asset is the protocol's own token, a falling price drains the value of the position just when the treasury needs it most.
Example
A DAO uses part of its stablecoin reserves to add 2 million dollars of liquidity to its TOKEN/USDC pool and stops paying farming rewards to outside LPs.
