Type parad0x.null in your address bar and load a website that has no server, no host, no DNS — just a name on Solana pointing at content on Arweave. Nothing to seize, no one to send a takedown to.

This is a small, open browser extension that resolves .null domains. It reads a name's account on Solana, follows the pointer to Arweave, and loads the page. No backend, no tracking, ~100 lines of resolver logic. Read every byte before you run it.

1. Load the extension (below).
2. Type parad0x.null in the address bar.
3. It resolves on Solana and loads the live page from Arweave.

Don't trust it — verify on-chain:

There is no Web Store listing yet — this is load-unpacked, on purpose, so you can read the code first.

git clone https://github.com/Parad0x-Labs/web0-resolver.git

1. Open chrome://extensions (or brave://extensions, edge://extensions).
2. Turn on Developer mode (top-right).
3. Click Load unpacked.
4. Select the web0-resolver/extension folder — not the repo root.
5. Confirm it loaded: you should see Null Resolver at version 0.1.2.

Now type any .null name. Done.

Updating later? git pull, then hit ↻ reload on the extension card. The version number is there so you can tell a fresh load from a stale one.

A normal site rents three things — a domain, a server, DNS. Pull any one and it's gone. .null removes all three:

  you type            the extension does                    you get

  parad0x.null   →    1. read the name's account on Solana
                      2. take the arweave_txid it points to  →   the page,
                      3. load that content from Arweave          from Arweave

• The name is a Solana account (a PDA on the null_registrar program). The owner controls it with a keypair. No registrar.
• The content lives on Arweave — paid once, stored permanently. No server.
• The link between them is one field in the Solana account. Only the owner's key can change it. No DNS, no admin panel.

The extension catches the navigation (including the case where your browser's omnibox sends name.null to a search engine), does the lookup, and redirects the tab. That's the whole thing.

Want to resolve .null without a browser — from an agent, a script, a backend? See AGENTS.md. It's the same logic in ~15 lines of Node, with the on-chain byte layout and the RPC gotchas documented.

A name is just an account on the null_registrar program — a one-time ~0.003 SOL of rent (refundable if you ever close it), no annual renewal. Self-serve registration (one-command CLI + a simple UI) is rolling out next. Until then, watch this repo or follow @Parad0x_Labs. The resolver here is read-only — it never asks for a key, never signs anything.

Click the extension icon → Advanced to set your own Solana RPC (e.g. Helius, QuickNode, Triton). Whatever you save goes first in the resolver's RPC chain; the public fallbacks still back it up.

Leave it blank and it uses a built-in public chain (publicnode + onfinality). Do not set api.mainnet-beta.solana.com — see pitfalls.

Browser support: works today in any Chromium browser (Chrome, Brave, Edge, Arc, Opera). Firefox and Safari ports, a mobile resolver, and a Web Store listing are on the roadmap.

• Read-only. The resolver only reads public Solana accounts and fetches public Arweave content. It never asks for, holds, or signs with a key.
• No backend, no analytics. Everything runs in your browser against public RPCs you can change.
• host_permissions is <all_urls> because it must see navigations to any *.null URL. It does nothing on non-.null pages.
