# POOL
Pools are the simplest way to earn free tokens on SharDex.\
Stake SDT, earn SDT. **It’s that easy!**
## How to Stake in Pool
**Step 1**
Click **\[Earn]**-**\[POOL]** to enter the pool page.
**Auto SDT** automatically compounds your rewards: any SDT you earn will be harvested and re-invested in the same pool for you.
**Manual SDT** does not automatically compound like Auto SDT. You’ll need to harvest and compound your earnings manually.
**Step 2**
Click **\[Enable]** button, and fill in the amount of SDT you want to stake, or directly stake SDT according to the balance ratio.
Click **\[Confirm]** to confirm staking.
Ratio
**Step3**
You can easily add more SDT to a Pool, or move some SDT to a more profitable pool. Click the **-** to take some SDT out of a pool, or the + to add more to the pool.
***Notes***
*1.Unstaking from the Auto SDT pool has some fee if you unstake within 72 hours.(But now it's still 0%)*
*2.When some pools expire, we will put them in the Finish option.*
