I recently heard that someone in the community accidentally entered the wrong address when transferring funds, and a $50 million transaction was lost just like that. What’s even more heartbreaking is that he had previously tested a small transfer of 50 US dollars, which went through without any issues, but the large transfer ended up being a problem.

It was only later that I realized there is actually a carefully designed scam scheme behind this. The scammers generate a set of "clone addresses"—the starting and ending characters are exactly the same as your real address, only a few letters in the middle are changed. When you copy the address, you can't tell the difference at all, and thus fall into the trap.

On the blockchain, a single slip-up can mean a lifetime of loss. So I’ve spent three years exploring and summarizing a foolproof transfer verification process, and I want to share it with you:

**Step 1: Check the start and end of the address.** After copying the address from your wallet, don’t rush to paste it immediately. Look at the first 4 characters of the wallet address (e.g., 7375) and the last 4 characters (e.g., 4af2), and repeat them in your mind. Then, paste the address into the exchange and verify whether these characters match exactly.

**Step 2: Verify the middle part of the address.** Return to your wallet and carefully examine the middle section of the address (e.g., 7365 2333 633), and silently read it out. Then switch to the exchange and check whether it’s the same. It may sound a bit troublesome, but this method can minimize the risk of "poison addresses."

**Step 3: Confirm the token and chain.** This is the final step and also the easiest to overlook. You must keep a close eye on the token (USDC or USDT) and the chain (Sui, Ethereum, or others), ensuring that both are exactly the same on both ends. Any mistake in token, chain, or address means the funds cannot be recovered.

Honestly, blockchain security isn’t just about the transfer moment; it’s a systematic habit.
