## Using the Longtail AMM

Longtail is the first AMM built with Arbitrum Stylus and the first native Dapp on the Superposition L3. Every pair on Longtail is paired against a Super Asset, ensuring that every transaction is incentivised and paying you yield for making trades!

1. Head to <https://long.so/>
2. Select any of the supported assets on Superposition Mainnet and start swapping!
3. Click on the "PRO" button in the Swap section to see stats and history on your selected liquidity pool and assets
4. Go to the "Stake" section to create your own pool and provide liquidity or add liquidity to an existing pool

{% hint style="info" %}
As Longtail is a V3 AMM, you can choose between providing liquidity in the full range, in an auto range or a custom range. Providing liquidity in the full range is the classic V2 setup, but unused liquidity outside of the current price will not earn fees. Auto will set an automatic range around the current price, while custom lets you set the liquidity range for yourself in tick spaces. Make sure to actively manage your liquidity if you set up a custom range!
{% endhint %}

**The more you swap and the more liquidity you provide, the more you earn.**
