2\. Find the auction pool to participate in. To participate in a sealed-bid auction, enter the following parameters:

* **Bid swap ratio:** the price you want to pay per token. This amount can not be lower than the floor swap ratio.
* **Bid amount:** the amount in ETH or USDT you want to spend.

4\. If everything is correct click **join** and enter the **join pool** page

5, Enter the bid, click **go** and confirm the transaction in MetaMask (or any other wallet you use).

*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.*

6\. Pool participants need to come back to manually claim the swapped tokens or unswapped ETH/USDT back. This can be done in one transaction at the end of the auction.

**A user can make only one bid transaction in one sealed-bid pool.**&#x20;
