# On-chain Configurations

## Investment Targets / Underlying Assets 

At the beginning of the product launch, Antimatter will list two mainstream assets as the underlying assets: BTC and ETH (more assets to be added to the list gradually).

1\. **Upward Exercise** 

Deposit Currency - **BTC, ETH** 

Alternate Currencies - **USDT**

2\. **Downward Exercise** 

Deposit Currency - **USDT** 

Alternate Currencies - **BTC, ETH**

## **Strike Price**

1. The strike price of each financial product is predetermined, while APY continues to fluctuate;
2. How to determine the strike price: 

* **Upward Exercise** - Strike Price = Current Price \* 105%, rounded to thousands (E.g. $51,000). The strike price would be $52,000, $53,000, and $54,000.
* **Downward Exercise** - Strike Price = Current Price \* 95%, rounded to thousands (E.g. $51,000). The strike price would be $50,000, $49,000, and $48,000.

## **Settlement Period**

1. Antimatter supports three periods, one day, one week or two weeks.
2. When a one-week period ends, the remaining period is a one-week INVEST, at which point the contract automatically creates a new two-week INVEST (the exercise price rule is as described above).

## **Min. & Max. Limit of Single Investment**

It is supported for users to configure the Min. and Max. deposit limit of single investment.

## **Total Allocation**

Each investment product has a total allocation (e.g. 100 BTC) and new orders will be suspended when all allocation is sold out (the product status changes to \[closed] and new products are automatically incremented).
