Your money,
squared away
Double Square gives your stablecoins a private balance on Ethereum. Hold, send and run payroll without your amounts, balances or counterparties going on the record.
Anyone can read a public wallet. Double Square gives yours an inner square.
Double Square runs on Ethereum, which is public by design: a block explorer shows what you were paid, what you spent and who you paid, to anyone who pastes in your address. That suits a protocol and fails a salary. Settlement stays on Ethereum; the details move into a balance only you can read.
Illustration: sample transfers pass through the Double Square mark. Before it, each one shows its amount and the receiving address. After it, the chain only shows that a private transfer happened.

With Double SquareWhat Double Square shows
Why the name
One wallet, two squares
The mark is the product drawn flat. Your money sits on Ethereum in plain view, and Double Square gives it a private square inside.
The outer square
EthereumYour stablecoins still settle on Ethereum, so anyone can check that a transfer happened and that it cleared.
The inner square
Private balanceAmounts, balances and who paid whom stay inside it, readable by you and by the people you decide to show.

Who it’s for
For money that’s nobody else’s business
If a stranger could learn something about you from a payment, that payment belongs in the inner square.
Everyday money
Rent, savings, a transfer to your sister. Ordinary payments that never needed an audience.
Freelance work
Clients pay you in stablecoins, and none of them can look up your other clients or your rates.
Payroll
Salaries go out on the same day, and colleagues still can’t compare pay on a block explorer.
