UniQTCUniQTC User Guide
UniQTC is a QTC / USDT market available at UniQTC Market. Orders, USDT escrow and settlement take place on BSC mainnet; sellers send QTC directly from their Quantus mainnet address to the buyer's address. The website also supports QTC, BSC USDT and BNB transfers from the same set of local wallets, along with on-chain order and trade history queries.
This documentation is based on the mainnet V2 pages, client and contract code in the repository as of September 24, 2026. Displayed balances, order statuses and statistics change as on-chain state changes. Before trading, check the current page, full addresses, on-chain records and the actual transaction you are signing. This documentation makes no price commitments and does not guarantee continuous network or service availability.
What you can do on the website#
| Section | Purpose |
|---|---|
| Market | View offers, create buy or sell orders, accept other users' orders and view trade history. |
| My orders | View on-chain orders involving your current local wallet, continue QTC delivery, cancel orders or claim available funds. |
| Transfer | Send Quantus QTC, BSC USDT or BNB directly from your local wallet. A standalone transfer does not automatically create a market order. |
Public pages support Chinese and English, as well as light and dark themes. Market listings can be viewed as cards or switched to a list. Buying, selling, signing, claiming and transferring require you to create or unlock a local wallet in this browser.
The basic steps of a trade#
- Create or import a local wallet and back up all 24 recovery words offline. The same recovery phrase generates a Quantus QTC address and a BSC address. USDT and BNB on BSC share the latter address.
- Fund the BSC address with enough BNB to cover network fees. Before your first market trade, follow the page instructions to bind both wallets.
- The buyer needs USDT, and the seller needs QTC. Refresh your balances, check the QTC quantity and the USDT price per QTC, then create or accept an order.
- The buyer's USDT enters the BSC escrow contract. The seller signs the QTC transaction with their local wallet and delivers QTC directly to the buyer's Quantus address bound to the order. After a buyer accepts a sell order, the seller may need to continue delivery from My orders.
- Once the system verifies that the QTC transaction has reached 3 block confirmations, it submits the BSC settlement. The seller's claimable USDT and any refund available to the buyer are shown according to the on-chain order status. When a Claim button appears, use the wallet entitled to those funds to claim them.
An order may move through stages such as open offer, accepted, delivery locked, confirming and delivered, or refund review and refunded. A successful page action does not mean final settlement is complete. Check the order status, block confirmations and on-chain receipt. See Placing Orders and Trading QTC and Delivery, Confirmations and Fees.
