In the first section, only the token contract address is needed.

* **Token contract address:** find the token contract address on [Etherscan](https://etherscan.io/).
* **Token symbol** and t**oken decimals** will be auto-filled after entering the token contract address.

The second section asks for the following parameters:

* **From:** is auto filled after entering the contract address.
* **To:** the currency to receive for the auctioned assets. On the Ethereum network the options are ETH and USDT. On Binance Smart Chain the options are BNB and USDT.
* **Floor swap ratio:** the minimum price bid offers a pool creator would accept. Bidders cannot bid below this ratio.
* **Amount:** the number of tokens to auction.

5\. Customize the fixed swap pool:

* **Allocation per wallet:** the maximum amount of tokens one wallet can purchase from your pool.
* **Participant:**&#x20;
  * **Public** opens the auction to everyone,&#x20;
  * **Bot holders** opens the auction to users who hold at least 0.5 bot in their wallet.
  * **Private** opens to exclusive users or groups secured by password.
* **Pool name:** for participants to identify the pool on the Bounce homepage.
* **Pool running time:** the time that the pool will be available.

6\. Once all parameters are entered, click the **launch** button and approve the transaction in Metamask (or whichever wallet used). Two transactions are needed to launch the pool.

* Approve spending limit:

*If a transaction error with very high gas fee (usually over 200 USD), appears please do not proceed and go back to the parameter page to check if everything is entered correctly.*

### Manual claim for pool creators

Pool creators need to come back to check the pool status page and manually claim the swapped ETH/USDT and any unswapped tokens. This can be done in one transaction at the end of the auction.
