Buying & selling

Every certed.one subdomain is a tradeable asset. The marketplace lets owners sell names and buyers acquire them, all settled in CTD.

Listing a subdomain for sale

Open one of your subdomains and set a fixed CTD price to create a listing. Each subdomain can have one active listing at a time. While listed, your name appears on the public marketplace and is flagged as for sale in the directory.

Buying at the listed price

Any signed-in user (other than the seller) can buy a listing instantly at its price. On purchase:

• the buyer's CTD balance is debited the listed price;
• 3% of the price is burnt as a listing fee and 10% is shared among the domain's stakers (when it has any);
• the seller is paid the remaining proceeds;
• any CTD staked on the domain is released back to its stakers;
• ownership of the subdomain transfers to the buyer;
• the sale is recorded in the name's price history.

The same split applies when a seller accepts a bid. See verification staking for how the staker reward is divided.

Verification score

Each listing shows a 0–99 verification score reflecting how much CTD the community has staked behind the name. A higher score signals a more trusted domain — learn how to raise it in verification staking.

Price history

Each subdomain's detail page shows a chart of previous traded prices and a table of past sales. This history is preserved independently, so it remains accurate even if a listing is removed later.

Prefer to negotiate?

Buyers don't have to pay the full asking price — they can place a bid the seller may accept. See bidding & escrow for how that works.
