# Longtail AMM

{% embed url="<https://long.so>" %}

Longtail is Superposition's premiere location for trading tokens, providing liquidity, and getting rewarded for every single transaction you make!&#x20;

It is also Arbitrum's cheapest and most rewarding AMM. Using Super Assets, every swap is eligible for yield.

Built as the first proof of concept AMM utilising Stylus, Long Tail is 4x more affordable than Uniswap V3 on Arbitrum.

(More information on whether this is the cheapest AMM in the entire web3 space coming soon :wink:)

Every swap is eligible for yield, randomly paid by an offchain worker. These rewards are virtually instantaneous, and are tied to the reward distribution.

Long Tail is a concentrated liquidity AMM with a custom fee structure per token address. Each pool is assumed to be sUSDC (Super USDC aka fUSDC)/other asset pool. This means that every swap utilising Long Tail is rewarded with yield.
