certed.one lets you claim a free certified subdomain in seconds, mint it as a name you truly own, manage its DNS records, and buy or sell premium names using the CTD token. This guide explains every part of the platform.

What is certed.one?

certed.one lets anyone claim a personal subdomain such as yourname.certed.one for free in seconds. Each name is minted as a certified domain you provably own and comes with full domain control, so you can point it at a website, an app, or any service you run. Names are tradeable assets: list yours for sale or bid on names owned by others, all settled in the platform's CTD token.

Core concepts

• Subdomains — a label you own under certed.one, e.g. blog.certed.one.
• DNS records — A, AAAA, CNAME and TXT records that control where your subdomain resolves.
• Hosted pages — publish a simple HTML page directly on your subdomain, no external host required.
• CTD token — the unit of value used to register names and trade on the marketplace.
• Marketplace — buy names instantly or place escrow-backed bids that sellers can accept.
• Verification staking — lock CTD behind a name to raise its 0–99 verification score and share in its sale.

Roadmap

Certified domains are the foundation. certed.one is building toward becoming the trusted certificate authority for web3 — issuing verifiable identity credentials for web3 services, enabling digital-native document signing against domains you own, and binding certified names to smart contracts so on-chain agreements carry a human-readable, verifiable identity.

Where to next

• Quick start — go from sign-up to a live subdomain.
• Managing DNS records — configure A, CNAME, TXT and more.
• Buying & selling — trade names with CTD.
• Token economy — how CTD is earned and spent.
