Newbies entering the circle are most likely to step on this pitfall, and finally someone has asked about it! When selling U, if the other party didn't use a real-name account to transfer money to you, and the money is in your card, while you have the U in your hands—at this moment, should you refund? Not release the coins? Or stubbornly proceed with the deal?
Let me tell you, this might be the most classic 'triangular scam' opening. The principle is simple: the money sent to you is likely paid by the scammer using a third party's (like an unsuspecting victim's) account. Once the real owner reports it, the bank may freeze or even recover the money, and you have already given the U to the scammer, ultimately leaving you with nothing and possibly getting involved in a money laundering investigation.
So the answer is clear: stop trading immediately, do not release coins! The safest way is to return this unexplained payment along the original path and blacklist the other party. It is better not to do this business than to risk having your card frozen and losing all your assets.
This real and tricky problem exposes the most vulnerable link in current C2C trading: trust must be built on the unverifiable information of 'whether the other party's payment account is safe and reliable.' When the trust cost of OTC trading is so high that it causes anxiety, we must think: Is there a way to free ourselves from reliance on 'strangers' bank accounts' when trading value?
This leads to the solutions that @usddio (USDD) and the decentralized finance (DeFi) concept it represents can provide. #USDD with stable trust#, this 'trust' in combating C2C trading risks can be understood as: trust should come from publicly transparent on-chain rules and the assets themselves, rather than vague background investigations of the trading counterpart.
Why is it said that USDD and the DeFi ecosystem can fundamentally optimize this trading experience?
Transaction equals settlement, no third-party risk: when using decentralized trading platforms (DEX) that support USDD or conducting P2P transactions through smart contracts, the 'atomic swap' model is adopted. This means that the buyer's USDD and the seller's U (or other assets) are exchanged on-chain through a smart contract, either succeeding simultaneously or failing simultaneously, with no intermediate state of 'money arrived but no coins given' or 'coins given but money not arrived.' This completely eliminates the aforementioned payment fraud and disputes.
Asset transparency and traceable paths: USDD, as a blockchain-based stablecoin, has completely open and traceable circulation records. While privacy is emphasized, the authenticity of the assets themselves and the certainty of transfers are 100%. Receiving USDD means that value has been definitively transferred from the sender's address to your address, with no possibility of freezing or withdrawal. You only need to verify the number of confirmations on the chain, not the identity of the payer.
No reliance on centralized intermediaries for 'real-name authentication': your trust is no longer dependent on the trading platform's review of whether the other party's bank card is real-name verified (which itself is difficult to ensure safety), but is instead based on the immutability of the blockchain network and smart contract code. You only need to safeguard your private key and interact with an on-chain address, eliminating the huge costs and risks of verifying the other party's identity.
Therefore, for all users troubled by C2C trading risks, a more advanced thought is:
Basic security: when conducting fiat currency transactions, insist on using OTC platforms or merchants that have undergone real-name verification with you and have a long-standing reliability, and never accept non-real-name transfers.
Advanced choice: gradually learn and use DeFi exchange channels based on stablecoins like @usddio (USDD). You can purchase USDD through compliant channels and then exchange it for other assets on DEX, completing the entire process on-chain, fully controlled and without entangling with untrusted counterparties at the fiat level.
The trust dilemma in over-the-counter trading highlights the friction costs of the old system. Assets like @usddio (USDD) and the DeFi ecosystem it supports are constructing a new trust paradigm: allowing the flow of value to return to its essence—relying on the certainty of mathematics and code, rather than the fragile and costly mutual trust investigations between individuals.
When you are anxious about 'whether to release coins,' it may be the right time to understand how a more autonomous and certain value exchange world operates.
