Guidelines to Avoid Illicit Funds & How to Handle Bank-Card Freezes

To protect users’ funds on the Tebbit platform, prevent illicit funds from entering, and reduce the risk of bank cards being frozen, please read this guide carefully and follow the rules to help maintain a safe and stable trading environment.

Chapter 1 How to Effectively Avoid Illicit Funds and Prevent Bank-Card Freezes

When conducting fiat trades, observe the following to avoid freezes or risk controls:

  1. Transfer/Receipt Rules
    • Do not accept transfers from non–real-name accounts: Incoming payments must come from accounts whose holder matches the counterparty’s verified identity. If you receive funds from a non–real-name account, refund along the original route to avoid bank risk controls.
    • Avoid third-party payments: Any third-party or proxy payment is high risk. Ensure the payer’s name matches the trading real-name identity.
  2. Handling Sensitive Keywords in Payment Memos
    • Do not include sensitive terms in transfer memos (e.g., “USDT, BTC, ETH, crypto”), which can trigger bank risk systems.
    • If a received transfer contains sensitive terms, consider refunding to the original account and note “mistaken transfer,” reducing freeze risk.
  3. Separate Cards for Receiving vs. Paying
    • Dedicated cards: Use different bank cards for receiving and paying to avoid mixed flows that trigger risk control.
    • Replace receiving cards periodically after high-frequency usage; move funds to a safer card.
  4. Fund Management & Flow
    • Minimize balances on receiving cards: Do not park large amounts for long. Periodically sweep to safe cards or cash-management accounts.
    • Rotate receiving cards across multiple cards to diversify risk.
  5. Card Sanity Checks
    • Test dormant or previously frozen cards first with a small transaction to ensure normal functionality.
Following the above can greatly reduce freeze risks and keep funds flowing safely.

Chapter 2 How to Perform Fund “Filtering”

To lower bank risk, apply fund-filtering strategies:

  1. Methods
    (1) Via Alipay/Yu’e Bao (or similar)    :
    • After receiving funds, top up to an e-wallet/balance or cash-management account.
    • After some holding period, transfer to another safe bank card.

(2) Via short-term cash-management products:
• Deposit into licensed platforms and buy short-term/on-demand products (e.g., 7 or 30 days).
• Redeem at maturity and transfer to a new card to avoid flags from frequent movements.

(3) Cash out then re-deposit to a new card (small amounts):
• Withdraw cash, then deposit into another safe card—preferably via branch counter.

Fund filtering reduces risk monitoring exposure. Always comply with banking rules and laws.

Chapter 3 How to Handle Bank-Card Freezes

Freezes are typically bank freezes or judicial freezes:

Section 1 Bank Freeze

  1. Main Causes
    • Bank risk control: Some regions restrict crypto-related transactions; memos like “BTC/ETH/USDT” may trigger freezes.
    • Unusual behavior:
    – Large transfers late at night
    – Frequent transfers with many unknown parties
    – Dormant card suddenly used for large sums
    – Sensitive memos
  2. What to Do
    • Contact the issuing bank to learn the reason.
    • Provide documents:
    – ID (passport, national ID)
    – Source-of-funds proof (payroll, trade records)
    – Bank statements (stamped)
    • Banks typically review within 7–15 business days.
  3. Prevention
    • Ask counterparties not to use crypto terms in memos.
    • Avoid relying on a single card; rotate cards.
    • Sweep balances to reduce large-sum flags.

Section 2 Judicial Freeze

  1. Main Causes
    • Suspected illicit flows (e.g., links to scams/pyramid schemes/illegal fundraising).
    • Being named in an investigation because of related fund flows.
  2. Process
    (1) Ascertain details: freeze term/type (temporary/long-term), case authority.
    (2) Prepare materials:
    • ID
    • Recent transaction proofs
    • Stamped bank statements
    • Income/source proofs (payroll, invoices)
    (3) Cooperate: provide statements and lawful source proofs.
    • Short-term (36–72h): wait for auto-unfreeze.
    • Long-term (6–12 months): may stay frozen until case ends.
    (4) After unfreeze, move funds immediately to avoid re-freezing.
  3. Prevention
    • Filter funds:
    – Separate receiving/paying cards; filter before onward transfers.
    – Optionally top up to e-wallet/cash-management, then withdraw to a safe card.
    – Require real-name payments; platform KYC name = bank name.
    – If receiving non–real-name funds, refund immediately with note “sent in error.”
