# How To Create Your Own Option

You will need 4 steps to create your own option:

1. Get the `OptionFactory`address 
2. Get either the `OptionFactory ABI` (web3) or the `OptionFactory interface` (solidity)
3. Define the parameters of your option
4. Call the `createOption()` function with the parameters

### 1. Get the OptionFactory address

1\) Instantiate our `ConfigurationManager` contract. Check our deployed contracts page [here](https://docs.options.pods.finance/developers/deployed-contracts).

2\) Call the function `getOptionFactory()`.

### 2. Get OptionFactory ABI or Interface

You can find both ABI and interface of OptionFactory in our Github repo. Always check if you are on the master branch to get our latest live update.

* Interfaces [here](https://github.com/pods-finance/contracts/tree/master/contracts/interfaces).
* ABIs [here](https://github.com/pods-finance/contracts/tree/master/abi).

### 3. Define your options parameters

In order to deploy a new option series, we need to define if the option will be a put, or call, expiration date and exercise size window are some of the option properties.

Below you can find all the parameters that you will need to define:

| Input Name         | Type    | Required                            | Description                                                                                                                                                        |
| ------------------ | ------- | ----------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| name               | string  | any                                 | The option token name (e.g., Pod BTC:USDC 300)                                                                                                                     |
| symbol             | string  | any                                 | The option token symbol (e.g., "PodPutBTC")                                                                                                                        |
| optionType         | uint8   | 0 / 1                               | 0 for Put, 1 for Call                                                                                                                                              |
| exerciseType       | uint8   | 0 / 1                               | 0 for American / 1 for European                                                                                                                                    |
| underlyingAsset    | address | contract address                    | Underlying asset address                                                                                                                                           |
| strikeAsset        | address | contract address                    | Strike asset address. Works with interest-bearing tokens aToken from Aave.                                                                                         |
| strikePrice        | uint256 | any                                 | Strike price (units of strikeAsset that buy 1 unit of underlying) (e.g., 12000000000 means you need 12000000000 units of strike asset to exercise 1 unit of WBTC.) |
| expiration         | uint256 | higher than current block timestamp | Expiration option date in UNIX timestamp (e.g., 1609401600)                                                                                                        |
| exerciseWindowSize | uint256 | higher than  86400 (24h)            | Duration of the exercise windows in seconds.                                                                                                                       |
| isAave             | bool    |                                     | If true, deploys a different contract version that supports liquidity mining on Aave (claim rewards)                                                               |

### 4. Call the `createOption()` function

Now that we have the `OptionFactory` address, ABI, interface and we have also defined the initial parameters, its time call the `createOption()`function.
