# Liquidity lock

Locking permanently leaves your liquidity in the pool. It's a signal to traders and holders that the liquidity behind a token can't be pulled — the standard way for a project to show it isn't planning a rug pull.

> ⚠️ **Locking is irreversible.** Once confirmed, the liquidity can never be withdrawn — not by you, not by the DeDust team, not by anyone. There is no unlock, no expiry and no partial release. Only permanent locking is supported.

You keep everything else: the position stays yours and keeps earning your share of [trading fees](/en/protocol/fees.md#trading-fees) and [boost rewards](/en/liquidity/boosts.md), which you claim as usual.

### Need to know before you lock

* [**CPMM v2 pools**](/en/liquidity/pools/types.md#cpmm-v2-pool) **only.** Classic and Stable-swap pools don't support locking.
* **Locking happens during the** [**deposit**](/en/liquidity/deposit.md)**, and only then.** To lock liquidity that's already in a pool, you have to [withdraw](/en/liquidity/withdraw.md) it and deposit again with the toggle on.
* **Pick the pool carefully.** Two pools with the same pair can perform very differently depending on the fee tier and the token fees are collected in — and a higher trading fee doesn't always mean a higher APR. Since you can't move the liquidity afterwards, compare the options before you commit.
* **Lock only what you can afford to leave.** The tokens stay exposed to price movement in the pair, and you have no way to exit the position.

### How to lock

1. Open the pool's page and press **Deposit**.
2. Enter the amount you want to deposit and lock.
3. Expand the **Advanced** section and enable **Lock liquidity permanently**.
4. Press **Deposit**, review the details and press **Confirm**.
5. Sign the transaction in your wallet.

### After locking

* The **Pool summary** shows the pool's permanently locked share of total liquidity — this is what traders check.
* [**Portfolio → Position**](https://dedust.io/portfolio) marks which part of your own liquidity is locked.
* Fees and boost rewards keep accruing and stay claimable indefinitely.
