# Claiming FLEX & Big Pay Days (BPD)

After participating in an auction day, users can claim their <mark style="color:blue;">**FLEX**</mark> starting **the next&#x20;**<mark style="color:blue;">**FLEX**</mark>**&#x20;Day**. Claims can be delayed, but **must be completed by Day 170**. Unclaimed <mark style="color:blue;">**FLEX**</mark> is forfeited.

When claiming, users must make a **permanent choice**:

They can claim <mark style="color:blue;">**FLEX**</mark> as **liquid**, or claim <mark style="color:blue;">**FLEX**</mark> as a **stake**.

Claiming as liquid sends <mark style="color:blue;">**FLEX**</mark> directly to the wallet. However, this choice has a permanent consequence.

{% hint style="info" %}
If an address **ever** claims auction <mark style="color:blue;">**FLEX**</mark> as liquid — even once — that address becomes **forever ineligible** for Big Pay Days.
{% endhint %}

Claiming as a stake automatically creates an **irrevocable stake** with:

* a minimum duration of **150 days**
* a built-in irrevocable bonus
* eligibility for Big Pay Days

#### Big Pay Days Explained

Big Pay Days are **random USDT refund events** funded by the auction.

From every auction contribution:

* **70%** is reserved for Big Pay Days

Each auction day, the protocol executes **at least 50 Big Pay Day refunds**.\
Eligible addresses are selected randomly using on-chain randomness.

When an address is selected, it receives **100% of its total auction contribution back in USDT**.

Important rules:

* An address **can be selected more than once**
* Receiving a refund does **not** remove eligibility
* No single refund can exceed **2% of the total BPD pool**

#### Example

If a user contributed **200 USDT** during the auction:

* If selected once → receives **200 USDT**
* If selected again later → receives **another 200 USDT**

This can happen multiple times over the 150-day auction period, or not at all. Selection is random and cannot be influenced.
