Payouts
Once your collection has made some money from mints, you can withdraw your funds from the collection contract.
To withdraw, go to your collection's page and click Edit, select the Contract tab, and find the Withdraw section.
Some versions of the contract require two transactions to withdraw, others require only one. You'll see what you need to do for your collection specifically on the page.

If your collection uses the affiliate system, you may see some funds remain in the contract after withdrawal. These are the affiliate's funds, and it will remain in the contract for them to withdraw.
