Yesterday, there was a chilling message in the circle: an old brother mistakenly copied the address while transferring money, and 50 million dollars went directly down the drain. The scariest part is that he cautiously tested with a small amount of 50U before the transfer, which went through — but when he transferred the large amount, the money disappeared forever.
The attacker's tactics are extremely insidious: they generate a batch of 'poison addresses' that have the same starting and ending letters as your real address, just waiting for you to confuse them when copying. It's like someone copied your house number but changed one digit in the middle, and both the mailman and you could be deceived.
In the dark forest of blockchain, every time you type on your keyboard could be a life-and-death moment for your lifetime savings. Here is the 'Nine-Step Transfer Life-Saving Method' that I have used for three years without any mistakes; please make sure to save it:
The core is just two points: say it out loud! Repeat it three times!
For 'head and tail': After copying the address from the wallet, don’t rush to paste it. First, mentally repeat the first 4 characters (like 7375) and the last 4 characters (like 4af2), paste it in the exchange, and then verify it again.
For 'middle': Look back at the middle part of the wallet address (like 7365 2333 633), mentally repeat it, and check it against the exchange again. Don’t find it troublesome; this can eliminate 99% of 'poison addresses'.
For 'currency and chain': Finally, keep a close eye on the currency (USDC) and the chain (Sui), and confirm that both sides are exactly the same before sending. If any of the currency, chain, or address is wrong, the money will be lost.
But is that enough?
I later realized that true security is systemic. It is not just about the moment you send, but also about what kind of assets you choose to hold as your value carrier.
If you have to anxiously battle a long string of garbled characters every day, worrying about being poisoned or forged, it indicates that the 'user-friendly layer' of this system is still too weak. This is also why, when managing large assets, I tend to choose those naturally transparent, verifiable assets with mechanisms that are simple enough to be impossible to forge.
For instance, a part of my core position is @usddio (USDD).
I choose USDD not just because it is stable. More importantly, its 'stability' comes from a completely on-chain, over-collateralized, verifiable mechanism. I do not need to verify some mysterious address; I just need to know that each USDD corresponds to real, over-collateralized BTC or TRX on the chain. Its security does not depend on whether I copied the address wrong, but on mathematics and open code.
In terms of transfer security, we rely on the 'Nine-Step Method' to combat the dark forest.
In terms of asset security, I rely on #USDD for stable trust, choosing protocols that engrain transparency and reliability in their genes.
True risk control starts with what you choose to hold.
Put your underlying assets in a place you can 'see' and 'verify'.
Follow @usddio, so your security goes beyond just the transfer step.
