# Lock rate
Unlike depositing liquidity [to existing pool](https://help.dedust.io/en/liquidity/deposit), for [newly created pools](https://help.dedust.io/en/liquidity/deposit/create), you need to enter token amounts for both sides of the pool. The proportion will define the initial exchange rate for this specific pool.
{% hint style="info" %}
Once you type in any amount, typically DeDust will automatically add another token amount, based on the existing exchange rate on the market. Toggle the ***Lock rate***, if you want to set own initial exchange rate.
{% endhint %}
1) DUST amount input
USDT amount auto-input
2) USDT amount input
DUST amount auto-input
{% hint style="info" %}
For newly created tokens, with no pools and market rate yet, you have to enter both amounts, in any case.
{% endhint %}
Once ***Lock rate*** option is deactivated you can type in both amounts manually, in proportion you need.
