# LP Promo

### <mark style="color:$danger;">No longer in use.  No Deposits accepted.  Withdraws only.</mark>

The LP Promo is designed to sustainably add liquidity to E280 without having to sell the token.

A key element to E280 as an arbitrage token is liquidity. The more liquidity, the more trading volume, the more taxes/fees are accumulated. The LP Manager is for anyone that wants to help contribute to liquidity by matching E280 with your favorite token, and creating a LP for you. While the LP sits in our smart contract, it starts at 50% ownership and goes up 1% every 28 days! This allows you to earn fees from trading, and more of the LP on top of that!

### Details <a href="#details" id="details"></a>

* Minimum stake length is 1 day.
* Maximum stake length is 3 years.
* No lockup required. Claim at any time after 1 day.

### How it works <a href="#how-it-works" id="how-it-works"></a>

* User Deposits Token of choice into smart contract
* The smart contract matches the deposit with equivalent USD value of E280
* The smart contract creates a LP with 50%/50% ownership between user and smart contract
* While the LP sits in the smart contract, the user earns additional 1% of LP each month
* User claims the LP at any time with current percent ownership sent to their wallet
