Your privacy.Built for Solana.

A considered workspace for your wallet, your data, and what you choose to reveal.

A workspace, not a cloak

It reads what the chain already shows, keeps your notes encrypted on this device, and conceals what your screen displays. Public blockchain data remains public.

Scroll

Inside, it is quiet. Outside, the chain is still public.

The Sanctuary

NERO is a workspace, not a cloak. It helps you read what is already public, keep what is yours on your own device, and decide what your screen shows.

Read what the chain already shows.

Wallet Inspector · Live data

Any Solana address, transaction signature, program instruction and token account, through a read-only Solana RPC. Clearly, and before you act.

Keep your notes sealed on this device.

Notes Vault · Local only

Sealed in this browser with AES-256-GCM under a key derived from your passphrase. Titles, text and links are all ciphertext. They are never uploaded.

Decide what your screen shows.

Screen Privacy · Local only

Balances, addresses and amounts stay concealed in this interface until you reveal one. It is for shared screens and recordings, and it changes nothing on the chain.

Receive at one-time addresses.

Stealth Addresses · Solana Mainnet

Solana uses public account addresses. A fresh receiving address separates activity, but does not make a payment private.

Public blockchain data remains public.

Cut in stone

Connecting a wallet does not make you private. Neither does a hidden balance, a local note or an ordinary transaction.

Working tools

Try them here. Your Solana workspace.

Explore the Solana workspace. Inspect public accounts, keep encrypted notes on your device and choose what your screen reveals.

Live data· through the relay

Wallet Inspector

A read-only look at any public address: balance, recent transaction count, whether it is an executable program, and its recent activity when an explorer index answers.

How it works

Understand the boundary.

Every piece of information here lives in one of four places. Knowing which is the whole point: it tells you who can see it, and what this product can and cannot do about that.

Public on-chain

Anyone can read it, now and later.

  • Addresses and their balances
  • Every transfer, with amount and time
  • Token delegates and program instructions
  • The fact that you transacted at all

Nothing in NERO changes this.

Stored in this browser

It stays on your device.

  • Your notes — as ciphertext only
  • Preferences and the Screen Privacy switch
  • A local activity log
  • A cache of public stealth announcements

Clearing browser data removes it. A forgotten passphrase cannot be recovered.

Sent to providers

What you look up leaves the browser.

  • The address, hash or calldata you inspect
  • Through this site’s relay to an RPC provider
  • To an explorer index for history and tokens
  • Program addresses and signatures to Solana RPC

They see the query and this server — never your notes or passphrase. Your wallet uses a provider of its own.

Hidden only on screen

Concealed here, unchanged everywhere else.

  • Balances, addresses, hashes and amounts
  • Until you press reveal on one
  • For calls, recordings and screenshots
  • Typed addresses shown as dots

The chain and the providers see exactly what they saw before.

The one on-chain mechanism

Stealth addresses, stated plainly.

Solana transfers use public accounts and transaction signatures. A fresh address can separate receiving activity; this interface does not implement a stealth-payment protocol or hide the recipient.

What it hides

  • A fresh address separates receiving activity from an existing account, without a privacy guarantee.
  • On-chain activity can still connect addresses.

What it does not

  • The sender, the amount and the time — all public.
  • A withdrawal to an address already known to be yours links the payment to you.
  • SOL and SPL token transfers remain public. This application is not audited.

Not in this build

No cloak, and no claim of one.

Not part of this build, and not implied anywhere in it: mixing, shielded pools, zero-knowledge transfers, private swaps or trading, anonymity or untraceability guarantees. Those integrations are not connected in this edition. Read the full explanation.

Reading the contract…

Every tool in this workspace works without it, and holding it changes nothing about what a public chain shows.

Asked before connecting

Does connecting a wallet make me private?

No. Public blockchain data remains public. Connecting only lets a tool ask for your signature when you choose to use one; the inspector, the vault and screen privacy work without it.

What does Screen Privacy hide?

Balances, addresses, hashes and amounts in this interface, until you reveal one. It is concealment for a shared screen or a recording, not encryption, and the chain is unchanged.

Where are my notes kept?

In this browser, as ciphertext: AES-256-GCM under a key derived from your passphrase. They are never uploaded, and a forgotten passphrase cannot be recovered.

What do stealth addresses hide?

Solana payments are public. A fresh address does not hide the sender, recipient, amount or time. This version does not implement a stealth-payment protocol.

Has it been audited?

No. This application is unaudited, and a passing test suite is not a security audit. The stealth contracts’ own audit status is not asserted either.

The threshold

Choose what you reveal.

No account and no sign-up. The inspector, the vault and screen privacy work without a wallet; connect one only when a tool needs your signature.
