Yes. You can reserve up to 10% of your Editions for yourself. These Editions can be minted by your address for free (excluding the gas fee) during the presale window.
You can mint the maximum that you allocated yourself in one transaction. For example, if you set aside 10, it’s possible to mint these all in one go or through 10 individual transactions.
Those allocated for yourself can be used as prizes in contests and giveaways. It is possible to allocate a further 10 to the Async team who could also potentially use these in giveaways. Find more information about this here.
