Root domains can enable the minting of segments (subdomains), but these segments cannot mint additional sub-segments. You can mint segments from any root NFD which has segmenting unlocked.
Root domains have two segment minting states, locked & unlocked. This defines who is allowed to mint segments from the domain root. When locked, only the root owner can mint. When unlocked, anyone can mint at a price specified by the owner.
Example:
When nfd.algo is locked, only the owner can register pooof.nfd.algo as a segment.
When nfd.algo is unlocked, anyone can register pooof.nfd.algo as a segment at the price specified by the owner.
You can utilize the Segments filter on the marketplace to find unlocked roots, or segments for sale.
There are two fees associated with segments, a platform fee and a root owner fee.
The platform fee for segments is $5/year, see the full pricing schedule here.
The root owner fee is determined by the root owner. Root owners receive the proceeds from root owner fees for their domains.
If you are minting a segment from a domain you own you will only pay the platform fee.
Example:
Segment Sale Price (USD)
Platform Fee (USD)
Root Owner Fee (USD)
