The problem

Internet businesses run on chat and stablecoins. Their money doesn't keep up.

Paid your invoice yesterday. Can you confirm it arrived?

Which invoice was that?

09:34✓✓
No clean view · receipts everywhere · reconciled by hand

Meanwhile, the business runs blind

Collection in one tool, payouts in another, treasury in a wallet, receipts in a sheet. What the owner actually knows, at any moment:

What's actually in stock?
Who has paid?
Who's overdue?
Where the margin is?
Lives in someone's head, or a sheet that's already stale

All of it happens inside messaging, not a finance dashboard. A fix that pulls the team out of chat is a fix they won't adopt.

Three jobs, one place

Collect, pay, and run. Without leaving chat.

01

Collect

Send a USDt invoice or payment link, track what comes in, hand the customer a clean receipt.

02

Pay

Pay your whole roster across borders in one approved move, with claim links for anyone without a wallet.

03

Run

A private AI brain on your device tracks inventory, reconciles payments, and keeps a clean ledger.

The payout wedge

Fund once.
Pay everyone.

Everyone chasing stablecoin commerce builds the checkout button. Almost no one solves the harder half: how a global team gets paid. One self-custodial action settles to contractors, teammates, and creators worldwide; anyone without a wallet redeems a claim link with a tap.

A day with Roster

Run the whole business without leaving the chat.

A client pays a USDt invoice straight from Telegram, and the brain matches it to the right invoice on its own. At month end the founder approves one payout for six people in four countries. Books clean, receipts stored, and none of the business's data ever left the founder's device.

Chat is the frontAI advises, never signsNo bank delay, no custodian
How it works · where custody lives

Your keys never leave your app. Chat is only the front.

Fund once · pay your whole roster
1

Fund your wallet

Keys live in your own app, built on WDK. Roster never takes custody.

2

Add your roster & approve

Add recipients, review, and approve the batch. You sign, every time.

3

Everyone is paid in USDt

WDK settles on-chain in seconds. Claim links cover anyone without a wallet.

The local business brain

A private AI that helps run the business, on your device.

Built on QVAC, the brain tracks inventory, suggests the better move, reconciles payments, and keeps the books. It advises; you decide. Nothing leaves your device.

The three pillars

We don't reinvent rails. We compose the three pillars into one operating layer.

WDK
Self-custodial wallet

USDt payouts + claim links. Keys never leave the user.

Pears
P2P coordination

Receipts and state sync, no central server.

QVAC
The local AI brain

Inventory, suggestions, reconciliation, on-device.
