Features

Everything you need to browse web3

A full browser that understands the decentralized web natively, with no extra configuration needed.

⛓
Native on-chain resolution
Resolves .hostdec domains by querying the contract directly on Arbitrum One. No DNS intermediaries, no extensions, no setup.
📦
Built-in IPFS
Includes a lightweight IPFS node. Sites load from the globally distributed network without going through any centralized gateway.
🔒
Privacy by default
No telemetry, no tracking, no mandatory accounts. Your browsing history stays on your device and nowhere else.
🌐
Traditional web too
Browse regular sites (https://) just like any other browser. HostDec Browser adds web3 capabilities — it doesn't replace existing ones.
🕵️
Anonymous browsing by default
No third-party cookies, no fingerprinting, no IP exposed to the decentralized sites you visit. Your web3 identity is yours alone.
⚡
Decentralized cache
Visited sites are stored in your local IPFS node. Subsequent visits are instant and require no internet connection.
Process

How a domain is resolved

Every time you type a .hostdec domain, the browser does this in milliseconds:

1
Intercepts the URL
Detects the hostdec:// protocol or .hostdec TLD and activates the resolver.
hostdec://mydomain.hostdec
2
Queries the smart contract
Calls getCIDWeb(tokenId) on the HostDec contract on Arbitrum One to retrieve the IPFS CID.
3
Loads from IPFS
The integrated IPFS node fetches and serves the content. No DNS, no servers, fully decentralized.
4
Renders the site
The site is displayed like any regular webpage. The NFT owner has full control over the content.
