What does burning or locking liquidity mean?
Burning or locking liquidity means the LP tokens that control a pool are sent to a dead address (burned) or time-locked, so the creators cannot pull the liquidity.
Because removing liquidity is the classic rug-pull move, burned or locked liquidity meaningfully lowers that specific risk. It does not protect against insider selling or other problems.
Whether liquidity is burned or locked is a contract-level check listed as a planned PumpScore signal.
