If I'm looking to sell one of the zil names I've purchased, how would I go about it?

You will own it with your private key so you can transfer it directly to a buyer. We’ll have simple escrow contracts to enable on chain sales (without having to use a 3rd party) soon after auction.

We are building a WhoIs service which are tools for safe p2p domain transfers. These tools will consist of a place to add a contact address so interested parties can reach out to you about your domain and smart contract tools to list a domain in a contract that will allow for safe transfer from one user to another.

The WhoIs service is scheduled to go live in September following an update from Zilliqa.
