FOR PEOPLE AND SOFTWARE

Payments that keep up.

Atto is digital cash for people and software. Fast confirmation makes room for the next thing. At a checkout, inside an agent, or between two steps in a workflow.

Pay at the counter. Get confirmation. Get on with your day.

PARALLEL BY DESIGN

Every account has
its own chain.

Your updates follow your account’s order. Other accounts can keep moving at the same time, without waiting for a global batch.

NINE DECIMAL PLACES

Small enough for a single use.

A tip. One request. A small digital purchase. Payments can be useful long before they add up to a whole coin.

THE SMALLER THE PAYMENT, THE MORE FEES MATTER

A small payment shouldn’t carry a big fee.

A fixed fee puts pressure on the minimum price: pay extra, charge more, or bundle purchases. Atto has no protocol fee to build into the price.

THE RECIPIENT CAN CATCH UP

Send now.
Receive when you’re back.

A confirmed Send makes funds available for the recipient to claim. They don’t have to be online when you pay.
