API · Nullifex

Our own APIs. Nobody else’s.

The Nullifex app, the extension and nullifex.fun connect only to servers Nullifex runs, and your browser enforces it. Here is each one, what it can and can’t see, and a live test you can run right now.

Watch it happen live in your browser

This page reads the security policy it was served with, pings each of Nullifex’s APIs, then asks your browser to reach outside addresses. Every number below is measured right now, on your device.

nullifex · network checkready

Running…

Check it without us: open your browser’s developer tools on any Nullifex page and watch the Network tab: every request goes to a nullifex.fun address. Or read the policy directly: curl -sI https://nullifex.fun/app | grep -i content-security-policy

Every API your device uses

None of them keeps access logs. Your IP address reaches them, as with any website, and is only held in memory to limit how many requests one client can make. It is never stored.

The appnullifex.fun/app

checking

Serves the app itself: its pages, its code and the proving files. Static files, the same for everyone.

Receives: Requests for those files.
Never sees: Anything you type or hold. The app runs on your device, and your keys never leave it.

The extension carries all of this inside its own package.

Solana gatewayrpc.nullifex.fun

checking

Reads Solana for the app: balances, transaction status and live updates.

Receives: The Solana requests the app makes, such as a balance lookup.
Never sees: Your keys, or which notes are yours.

The Solana node behind it sees Nullifex’s server, never your IP address, your browser or the page you’re on.

Relayerrelayer.nullifex.fun

checking

Submits your private transactions and pays their network fee. Quotes fees, trades and NullifexSwap routes.

Receives: Each transaction with its proof, and quote requests: tokens, amounts, and a withdrawal’s destination. For NullifexSwap, the destination chain, recipient and amount.
Never sees: Your keys or your balance. It can’t change where funds go: your proof fixes the recipient and the fee.

Indexerindexer.nullifex.fun

checking

Serves public on-chain data, the same for everyone: encrypted notes, the Merkle tree, and token names, prices and logos.

Receives: Requests for that public data.
Never sees: Which notes are yours. Your device finds them by decrypting, and checks the data against the root the Nullifex program records on-chain.

nullifex.fun

May connect toNothing: it only loads its own files

Nullifex extension

May connect toThe Solana gateway, relayer and indexer

Endpoint reference for the relayer and indexer: Docs → Relayer & indexer API. Anyone can run their own.

Nothing else runs in your browser

No third-party code

Every script comes from Nullifex’s own server or the extension package. No analytics, ads, tag managers or chat widgets.

No outside fonts or images

Fonts are Nullifex’s own files. Token logos come through Nullifex’s indexer, so the sites that host them never see you.

No cookies, no accounts

Nothing to sign up for, and nothing that follows you from site to site.

No remote code in the extension

Everything it runs is inside the package Chrome reviewed. Its only permission is storage.

Where outside services come in

Some work needs the wider network. Nullifex’s servers do it for you, so these services hear from Nullifex, not from you.

Service	What Nullifex asks it for	What it sees
A Solana node	Reading Solana and sending transactions, for the gateway and the relayer	Nullifex’s server. Your requests arrive without your IP address, browser or origin.
Jupiter	Trade routes, lending markets, the token list and prices	Nullifex’s server, and the trade or position being quoted, which becomes public on Solana anyway.
NEAR Intents	NullifexSwap cross-chain orders	Nullifex’s server, and the order you choose: destination chain, recipient and amount.
Public storage networks	Token logos and details, where token creators publish them	Nullifex’s server only.

Your own choices stay yours: a wallet you connect, such as Phantom, is its own software with its own connections. Links you open, such as Solscan or X, take you to those sites. And anything you shield, withdraw or send to a deposit address is public on Solana, like any Solana transaction.
