Locked liquidity: what it means and why it matters in a memecoin
In short
- Liquidity is the money deposited in a pool that makes it possible to buy and sell a token.
- If the creator can withdraw it, they can leave the token with no way out: that is why it matters that it is locked or burned.
- Locking is not the same as burning: a lock expires, a burn is permanent.
- Even with locked liquidity, a token can fall or carry other risks.
What liquidity is
When you buy or sell a token on a decentralized exchange, there is no person on the other side: you trade against a pool, a fund that holds money (for example SOL, USDC or BNB) and tokens. That money is the liquidity. The more there is, the less a large buy or sell moves the price.
Why it matters so much
Whoever creates a token usually provides the initial liquidity and, in exchange, receives special tokens called LP tokens. Whoever holds the LP tokens can withdraw the money from the pool whenever they want. If the creator keeps them with no restriction, they can pull everything at once, and the token is left with no way to be sold. That is a rug pull.
Locking and burning: not the same thing
- Burning the liquidity: the LP tokens are sent to an address from which they cannot be recovered. The liquidity stays in the pool permanently.
- Locking the liquidity: the LP tokens are deposited in a contract that holds them for a period, for example six months. While the lock lasts, the creator cannot withdraw it; when it expires, they can.
That is why it is worth checking what percentage is locked or burned and until when. A lock of a few days offers little peace of mind.
How to check it
- On a pool explorer like DexScreener, see how much liquidity the pair has. Some show a padlock when it is locked.
- On Solana, a checker like RugCheck reports what percentage of the liquidity is locked or burned.
- On Ethereum-type or BNB Chain networks, there are services that show LP token locks and their expiry date.
- Check that whoever locks is really the one who controls the liquidity: sometimes only a small part is locked.
On launch platforms like pump.fun, liquidity is usually handled by design, but it is still worth verifying it in each case.
Total liquidity and its relation to the token's value
Also look at the liquidity relative to the token's total value (market cap). If liquidity is a tiny fraction, for example under 1%, a single large sale can sink the price, even if the liquidity is locked.
What locked liquidity does not solve
- It does not stop the creator from selling their own tokens.
- It does not protect against a honeypot.
- It does not prevent the price from falling because nobody wants to buy.
It is a positive sign, but only one of several.
