What is Tazor

USDT checkout for businesses on Whitechain: customers pay without gas, merchants refund in one click, accountants get the export. Also: B2B approvals.

Tazor is USDT checkout for businesses on Whitechain: customers pay without gas, merchants refund in one click, and accountants get the export.

How a sale works

  1. The customer pays. One signature in their wallet, or a transfer from an exchange such as WhiteBIT. They need USDT only: no WBT, no gas. Payment is confirmed on Whitechain in about 4 seconds.
  2. The merchant refunds, if needed. One click on the Checkout page. A refund can only go back to the customer, and never for more than was paid.
  3. The accountant gets the export. Reports lists every payment and refund with its transaction, as a CSV.

Set up at Start accepting USDT: a pay button for your website, or a payment link for chat, email or a QR on the counter. Details are in Checkout, refunds & subscriptions.

Also built: B2B approvals

For business-to-business payments, Tazor also does invoicing and recurring billing in USDT. A supplier sends an invoice as a link; the buyer's approvers check it and approve it with a passkey (Face ID, a fingerprint or the device PIN); the USDT moves on Whitechain in a few seconds.

What makes it different

  • Approvers are verified people. Each approver is checked against WhiteBIT's WB Soul identity registry in the same transaction as the payment.
  • Your company decides who approves. Roles live on your company's ENS name (for example acme.taz0r.eth) and are proven onto Whitechain, not taken from a Tazor server.
  • Payments can't be redirected. Your phone rebuilds what you sign from the invoice link and refuses if the contract disagrees. Removing a person takes effect in seconds.
  • Payments can't be stopped. Anyone can submit a signed payment. If Tazor's relayer is down, you can submit it yourself, or send it through Ethereum.

The end-to-end B2B cycle

  1. Receive. A supplier sends an invoice link, or collects under a mandate.
  2. Pay. The buyer's approvers check the invoice and approve it with a passkey; USDT moves on Whitechain.
  3. Control. Roles come from the company's ENS name, limits from its policies, and anyone can be removed in seconds.
  4. Books. Every payment can be exported for your accounting system, alongside the on-chain statement.

The Product tour walks through each step in the app.

What you can do with B2B

  • Create invoices and share payment links.
  • Pay one invoice, or a run of up to 50 invoices with one signature.
  • Set up mandates so a supplier can collect a fixed amount each period.
  • Export payments for Tally, Xero, QuickBooks or as an ISO 20022 camt.054-style file.

What it is not

Tazor is a self-custodial business account and billing layer. It holds no deposits and has no bank or card rails. There is no wallet, seed phrase or gas for approvers to manage.

This build runs on Whitechain Sepolia, a test network. Some parts are simulated; see Testnet simulations.
