You may notice that some projects have a subdomain like dev.mirror.xyz. Currently, the Mirror core team rewards them with a $WRITE token to selected projects which gives access to register a subdomain and entry into the Mirror DAO.
Please note that this process may take some time, as $WRITE is being allocated on a case by case basis.
In the future, the Mirror core team plans to hand over this selection process to the Mirror DAO so it's a fully community-led process.
In the meantime, if you'd like to be considered to receive a $WRITE token, join our Discord and post your project URL in the #pitch-spotlight-project channel.
Once you've received a $WRITE token, you can go to mirror.xyz/join, "Burn" your $WRITE, and confirm the transaction.
