Security Notice on Preventing Common OTC Trading Scams

Dear Users,

To help you identify common OTC trading scams and protect your funds and digital assets, SUNX reminds you: Trade through the Platform’s official OTC channel and verify each order, payment details, and actual receipt of funds individually.

A buyer marking an order as “Paid,” or providing a text message, screenshot, or payment receipt, does not mean that funds have arrived. When selling digital assets, release them only after confirming that the corresponding payment has actually reached your own receiving account.

I. Fake Payment Notification Text Messages

Scammers may use the phone number displayed in your payment method to send a fake payment notification while marking the order as “Paid” and urging you to release digital assets.

Prevention advice:

Log directly into your bank’s or payment provider’s official app and check actual incoming transaction records. Do not confirm receipt solely from messages, notifications, or the counterparty’s verbal statements.

II. Requests to Pay on Someone Else’s Behalf and Incorrect Payment QR Codes

1. Disguising a Payment Request as Proof of Payment

Scammers may send screenshots requesting you to pay on their behalf, making them look like completed transfers and inducing you to release assets without receiving payment.

Prevention advice:

Distinguish carefully between a “Payment Request” and a “Successful Payment.” Rely on actual incoming transaction records in your account, not the appearance of an image.

2. QR Code Amount Does Not Match the Order

A payment QR code may contain a preset amount. For example, an order requires 500 yuan, but the scanned payment page shows 5,000 yuan. Failure to check may result in overpayment.

Prevention advice:

Verify the recipient, amount, currency, and order information before paying. If anything differs, pause payment and clarify the reason first.

III. Forged Screenshots or Transfers to Other Accounts

Scammers may provide altered payment screenshots or receipts, or transfer funds to another account and then demand that you release digital assets.

Prevention advice:

Rely on actual transaction records in your own receiving account. Verify the amount received, payer’s name, receiving account, and transaction time. Do not release assets if the corresponding payment has not arrived.

IV. Confusion Through Repeated Orders of the Same Amount

Scammers may submit several same-amount orders in quick succession through one or multiple accounts, using identical amounts and similar timestamps to confuse payment records.

For example, the first four orders are paid, but the fifth is unpaid and marked “Paid,” with an earlier payment record used to demand release.

Prevention advice:

1. Match every order with its corresponding incoming transaction. Do not use one receipt of funds to confirm multiple orders.
2. Verify that the paying account name matches the counterparty’s verified identity on the Platform.
3. If records cannot be matched, payment is insufficient, or names differ, pause release and contact official customer support.
4. Do not skip verification because the counterparty is pressuring you.

V. Collusion Using Another Person’s Payment Receipt

Two users may simultaneously submit orders for the same amount. One pays but does not yet mark the order as paid; the other does not pay but marks “Paid” and uses the first user’s screenshot to request release.

Prevention advice:

Identical amounts do not mean that payments belong to the same order. Verify the actual payer, incoming transaction, and order counterparty individually to avoid matching funds to the wrong order.

VI. Underpayment or Confusion Between Amount Units

A counterparty may pay only part of the amount or confuse the digital asset quantity with the fiat payment amount.

For example, an order requires 10,000 yuan, but only 1,000 yuan arrives; or the buyer mistakenly assumes that purchasing 1,000 USDT requires paying only 1,000 yuan.

This may result from an operational mistake or involve fraud. A difference in amounts alone does not establish the counterparty’s intent.

Prevention advice:

Check the total payable amount, payment currency, and actual amount received. If payment is insufficient, pause release and resolve the matter through order communications and official customer support.

VII. Impersonating Support, Official Staff, or Trusted Guarantors

Scammers may add you as a contact under the pretext of “long-term cooperation,” then change their avatar or nickname to impersonate support, official staff, industry figures, or team members. They may offer false guarantees and encourage off-platform trading.

They may also use group chats or forged screenshots to request early release or transfers to a specified address.

Prevention advice:

1. Do not verify someone’s identity solely from an avatar, nickname, group membership, or screenshot.
2. Do not accept unverified private guarantees or release assets early because of a supposed “official guarantee.”
3. Do not follow social chat instructions to transfer assets to unfamiliar addresses.
4. Verify claims about support identities or transaction handling through SUNX’s official customer support channels.

VIII. Three-Party Trading and Replacement of Receiving Accounts

Scammers may contact both buyer and seller, forward genuine order screenshots, or use someone else’s name to make the buyer believe they are dealing with the order’s seller. They then direct payment to an account selected by the scammer.

The buyer may have paid while the actual seller has received nothing.

Prevention advice:

1. Pay only to the receiving account displayed on the order page whose name matches the counterparty’s verified identity.
2. Do not accept last-minute account changes through WeChat, other social media, or private messages.
3. Do not send a specified person’s name or help create potentially misleading transaction evidence at a third party’s request.
4. If screenshots and orders differ, or someone requests payment on behalf of another person or to a different account, stop and contact official customer support.

IX. Handling Suspicious Situations

Stop suspicious payments, releases, or asset transfers and preserve:

• Platform order numbers and details;
• Actual payment and receipt records;
• Communications within the order and outside the Platform;
• Links, screenshots, account details, or addresses provided by the counterparty;
• Digital asset transfer records and transaction hashes, where applicable.

Report through SUNX’s official customer support and cooperate with verification. If funds have been lost or fraud is suspected, promptly contact your bank, payment provider, and relevant local authorities.

X. Important Reminder

Release only after actual payment receipt, verify orders individually, use accounts under verified real names, reject private guarantees, and do not move transactions to unofficial channels.

These scams do not represent all risks, and preventive measures cannot guarantee protection against every loss. Comply with local laws, bank and payment provider requirements, and SUNX OTC trading rules.

Thank you for your support and trust in SUNX.
