Money for the internet that a shop can check for itself.
Send money, sell things and trade, with no bank or company in the middle. Payments arrive in about five seconds and cost less than a cent.

Pay, get paid, trade. Nobody in the middle.

Get paid, and know it
Every order has its own number, so you see exactly which order was paid. The money goes straight to you. If you want to give some back, the refund is linked to the order.
-
Buy and sell without an exchange
Put coins up for sale at your price, or take someone else's offer. The trade happens in one step: you get what you paid for, or nothing happens and you keep your money.
-
Make your own token
Loyalty points, a game currency, a community coin. Give it a name and say how many. Copies are easy to spot: each token has its own pattern, and a copy's is different.
-
Escrow that can't run off with the money
Pay into escrow and release it when the goods arrive. If there's a dispute, a referee decides who gets it. The referee can be a person or a program, and can only ever pay the buyer or the seller.
How it works, for the technically curious
- 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. Getting paid and refunds work on it today; trading, tokens and escrow arrive with the next one.
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.
// Show a checkout for one order client.openCheckoutModal({ merchantAddress: 'imntest:q...', amountImn: '12.5', invoiceId: 'INV-1042', onSuccess: (payment) => { markOrderPaid(payment.invoiceId); } });
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 and no share for the developers.
| Years | Reward / block | Mined in period | Supply at end | Inflation at start |

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.
