About Domains

What are .hostdec domains?

.hostdec domains are unique names registered as ERC-721 NFTs on the Arbitrum One network. Unlike traditional domains, which are rented annually from centralized registrars, a HostDec domain is a permanent digital asset you truly own: you pay once and it's yours forever.

Each domain points to content published on IPFS via an identifier called a CID. The smart contract immutably records the relationship between the domain, its owner, and the content it points to. No one can censor it, cancel it, or take it from you.

When you register a domain on HostDec, you can access it both as a HostDec subdomain and natively through the HostDec browser, allowing you to view content directly and easily.

Features

♾️

Perpetual, no renewals

You pay once with HDEC tokens. There are no annual fees or risk of losing your domain by forgetting to renew.

🔒

True on-chain ownership

The NFT lives in your wallet. No one can cancel, transfer, or censor it without your signature.

🔄

Always-updatable content

Link an IPFS CID to your domain and update it whenever you want.

💱

Transferable and sellable

The domain is a standard ERC-721 NFT. You can sell or transfer it on the Marketplace or OpenSea.

⚡

Minimal gas on Arbitrum

Arbitrum One is a Layer 2 network on Ethereum: confirmations in seconds and fees in cents.

📜

Version history

The contract maintains a circular buffer with the metadata CID history. Queryable on-chain by anyone.

Pricing

Price by name length
