# The 3 IDO Periods

Our IDOs are done in **3 stages**:

* **Staking Period →** Users stake IDIA/vIDIA & get allocation
* **Purchase Period →** Users buy their allocation
* **Claim Period →** Users claim the tokens that they purchased

Let's take a deeper look at each stage:

### Staking Period

During the *Staking Period*, we will determine how many project tokens will be allocated to you.

To get allocation, you need to stake your IDIA/vIDIA during this stage. The more & longer you stake, the more allocation you get, as explained in [Launchpad FAQ](/impossible-finance-faq/launchpad/launchpad-faq.md#how-is-allocation-calculated).

### Purchase Period

After the *Staking Period* is finished, the Purchase Period begins. As the name suggests, this is the Period where you will be able to buy the tokens allocated to you.

This usually lasts around 1 day to give people in every part of the world time to buy.

{% hint style="danger" %}
You must purchase the tokens during this period! Any allocation that is not bought when the period ends is forfeit and cannot be bought afterwards!
{% endhint %}

### Claim Period

Once the *Purchase Period* has finished, the Claim Period will begin shortly after.\
\
During the *Claim Period,* you will be able to claim the tokens you purchased and proceed to transfer them to your wallet.

{% hint style="success" %}
The *Claim Period* has no end, as long as you bought tokens during *the Purchase Period,* you will be able to claim your tokens whenever you want.
{% endhint %}

{% hint style="info" %}
Note that some IDOs are Airdropped, in which case there is no need to Claim the tokens.

\
If airdropped, the tokens you bought will be automatically transferred to your wallet.
{% endhint %}
