How to sell into a Launch

You can sell NFTs back into the pool as long as the sale is active by clicking "sell NFT" at the top of the trade box. Pick how many you want to sell and hit swap (you will need to approve a transaction so the platform can sell your NFT). You will receive the quoted price from the trade box.
Keep in mind, the owner of the launch can end the sale in 2 ways. If all NFTs are bought out of the pool or when the time runs out. The owner can then, at any point chose to close and end the sale withdrawing all funds.
