Testnet running Quantum-safe wallets Tokens built in 5-second BlockDAG Ticker IMN No premine 5% maintenance fee, first 3 years

Money built for the quantum age.

Every wallet is quantum-safe from day one. Make your own token and trade it without an exchange. Keep savings a thief can't empty. All of it is built into the coin itself, on a BlockDAG that adds a block every five seconds, mined fairly on ordinary graphics cards.

§2Features

Safe for decades. Useful today.

Built to last

Safe from tomorrow's computers, too.

Every wallet is locked twice: once with today's proven standard, and once with a newer lock designed to resist future quantum computers. Spending needs both keys.

You get quantum protection now, without giving up the security that already works. Why two locks?

Build on it

Your own token

Make one in a minute and trade it with anyone. No exchange.

Save it

Safe from thieves

Vault withdrawals wait, and your backup key can stop them.

Spend it

Ready for shops

Under a cent a payment, in a block within seconds. Order numbers, refunds and escrow built in.

Every feature, and how we compare

How it works, for the technically curious
  • Wallet addresses carry two public keys, Ed25519 and SQIsign (a post-quantum signature scheme in NIST's standardisation programme). Spending needs a valid signature from each; nodes check them in parallel. SQIsign was chosen over the more common ML-DSA and Falcon for size: its key and signature together are 283 bytes, against about 1,560 for Falcon-512 and 3,730 for ML-DSA-44.
  • A block every five seconds. When two miners find one at the same moment, both are kept and put in order (GHOSTDAG), so a short block time wastes no work.
  • A full node is small enough for a shop to run on a cheap server and check its own payments, instead of trusting someone else's.
  • Mining uses graphics cards. The algorithm, Hallmark, is FishHash with our own seed: each hash reads randomly across gigabytes of memory.
  • Escrow, trading and tokens are fixed rules every node checks, not contracts anyone can deploy, which keeps them small enough to review.
  • Trades with other chains use hash locks with SHA-256, which Ethereum-style chains can check too.

The details are in the specification and the developer cookbook.

This is a test network, and test coins have no value.

§3Get the app

Your wallet, in its own window.

Install it and open it. It checks your payments itself, with nothing to set up.

Your computer may warn that the app is from an unknown publisher. On Windows choose "More info", then "Run anyway"; on a Mac, allow it once in Settings, Privacy & Security. Test network only. All downloads and checksums to confirm a download is genuine.

§4Supply

Every coin is mined, on a schedule nobody can change.

The reward halves every four years, four times, and then stays at 0.3125 IMN per block for good, so miners are always paid to secure the network. There is no premine. For the first three years, 5% of each block reward goes to a maintenance fund that pays for the network's servers and development; the rules send it to one public address and stop it automatically after 18,921,600 blocks.

§5For shops

Add it to your shop in minutes.

On WordPress, install the WooCommerce plugin and enter your address. Customers scan a code to pay, and the order is marked paid by itself.

  • No sign-up and no account with anyone
  • The money goes straight to your address
  • The Refund button works as you'd expect
  • For other sites, a few lines of JavaScript

Test network only for now. Don't use it for real orders yet.

§6Where it stands

A test network is running. Here's how far along it is.

Test coins have no value. There is no coin to buy yet, so anyone selling IMN today is not us.

Works today

  • Nodes on three continents
  • Wallet and explorer on this site
  • Mining with graphics cards, and a mining pool
  • Order numbers, so a shop sees which order was paid
  • Refunds linked to the order
  • Shared wallets that need two people to approve
  • Payments older than 12 hours can never be undone
  • A node small enough for a shop to run
  • Wallets protected against future quantum computers
  • Trading, tokens and escrow
  • Subscriptions and savings vaults
  • A desktop app for Windows, Mac and Linux
  • Four rounds of security testing, every finding fixed

Being built

  • Swaps with Ethereum, in the wallet
  • Encrypted connections for miners
  • A mining pool built for many miners

Not started

  • A full independent audit
  • Swaps with Bitcoin
  • Hardware wallets
  • Main network

Security testing, in the open

Every feature has been through four rounds of penetration testing, with reviews by three AI models (MiniMax, GLM and DeepSeek). Every finding was fixed and covered by a test; the fixes are described in the changelog. A full audit by a security firm costs more than the project has today; it is planned for when the maintenance fund or community support can pay for one.
