# Liquidity lock
Locking your liquidity helps build trust for both the token and the project behind it.
{% hint style="info" %}
This liquidity lock option is only available in pools of [CPMM v2 type](https://help.dedust.io/en/pools/types#claimable-fees-pool-cpmm-v2).
{% endhint %}
If you want to lock your liquidity forever:
1. Go to liquidity pool's page. Let's assume it's [DUST/TON](https://dedust.io/pools/EQATCf6DbZhnkqGvWfVg4WjgLoS0J2GRSY7_DBx4yHenxdXQ) pool[^1], where we've already had ≈ $100 equivalent liquidity position.
2. Press **"Depoosit"**.
3. Input the amount you're going to lock forever in this specific pool. Let it be ≈ $10 in total.
4. Go to **Advanced** section and toggle ***Lock liquidity permanently*** switcher. And press **"Deposit"**.
{% hint style="warning" %}
Once permanently locked, this liquidity cannot be withdrawn. But it still belongs to you and lets you earn share of liquidity providers earnings, from trading fees. As well as other earnings from this liquidity.
{% endhint %}
{% hint style="info" %}
Consider that even same-assets pools performance may differ — depending on trade fee tier, token(s) in which the fee is collected, and [other conditions](#user-content-fn-2)[^2]. And higher trade fee doesn't always mean higher APRs.

5. Check all the details. ***Lock liquidity*** row will say "Yes". If everything is correct, press **"Confirm"**.
6. Sign the transaction in your wallet app.
{% hint style="success" %}
All done. Your liquidity is now permanently locked.
{% endhint %}
Check the **Pool summary**. There is now a row with pool's ***Permanently locked*** share of total liquidity.
And check the **Position** section. There is now an indication of your own liquidity share, that is locked.
