Liquidity Locking
A mechanism where a token project's liquidity pool funds are locked in a smart contract for a set period so developers cannot drain them.
Also known as: LP lock, liquidity lock
Last reviewed: 10 June 2026
Liquidity locking involves a project depositing its LP tokens into a time-locked third-party smart contract, making it mathematically impossible for anyone, including the developers, to withdraw the funds before the lock expires. Services such as Team.Finance or Unicrypt are commonly used for this purpose.
While liquidity locking is a meaningful safeguard against an immediate rug pull, it is not a guarantee of legitimacy. Common evasion tactics include: locking a tiny fraction of total liquidity while keeping the rest free; setting very short lock durations (days or weeks); using a fake locking contract that appears legitimate but has a hidden backdoor; or locking liquidity while still controlling a huge portion of the token supply that can be dumped to crash the price.
Investors should verify locks directly on the locker platform, confirm the locked amount represents the majority of total liquidity, check the lock duration versus the project's stated roadmap, and examine the token distribution for whale concentrations.
