# Initialization

There are two entrypoints are responsible for initializing the new DEX pool contract.

{% hint style="warning" %}
These entrypoints should be called only by `Factory` contract address. 
{% endhint %}

Both methods are called as internal operations of one entrypoint of Factory: [start\_dex](https://docs.quipuswap.com/smart-contracts/quipuswap-stable-swap-dex/factory/initialize-new-dex-flow/start_dex "mention").

### Copy core dex lambdas

This method receives big\_map of `nat -> bytes` - lambdas of [dex-methods](https://docs.quipuswap.com/smart-contracts/quipuswap-stable-swap-dex/standalone-dex/dex-methods "mention").

{% endcontent-ref %}

### Freeze

{% hint style="info" %}
The DEX pool contract deploys with `started = False`. This method changes this field.
{% endhint %}

This method is used only to trigger "unfreeze" of the contract after copying DEX lambdas - the last needed lambdas to enable full functionality of DEX pool.
