# How it works

### You have two paths: create a Pool or join an existing Pool.

#### To create a Pool

1. Go to [the RockPool main page](https://rockpool.nftfy.org/) and click  **“Create a Pool”**;
2. Then choose an NFT on **OpenSea (ERC721) listed at a fixed price,** paste the NFT URL in the indicated field, and click on **“Start a Pool”** (of course, do not forget to connect to your wallet);
3. Choose your RockPool parameters. If your Pool is private, you will also need to define the **curator fee** percentage – this is a fee, on the NFT value, that the Pool creator will receive after completing the NFT purchase through the platform;
4. Don't forget to **Claim your fractions** as soon as the Pool is finished, that is, it reaches the required amount.

Once the NFT is purchased, it is fractionalized using the Auction method and re-registered in our marketplace for a higher Reserve Price. You must define the **Auction Price Multiplier** as a parameter to be applied to the current NFT price to set the **Reserve Price (the minimum amount needed to buy the entire NFT)** after the fractionalization.

#### To join a Pool:

1. Click **“Join Pools”** on the [RockPool main page](https://rockpool.nftfy.org/);
2. Choose the NFT you want in the **"Hot Pools" tab** and define the value you want to join; 
3. Complete the **Claim** process of your fractions once the Pool is finished.

After the contract buys the NFT from OpenSea, it sends the NFT to the fractionalizer contract, which **holds the NFT and issues ERC20 fractions** to be “claimed” by Pool participants. Thus, **the NFT is “locked” in the Smart Contract and can only be completely withdrawn upon payment of the Exit Price or with 100% ownership of the fractions.**
