The address has been pasted—don’t just look at the first and last few digits first.

Copy the address from the payment page, then go back to the withdrawal page to prepare for confirmation. Don’t use the most recent successful record to compare. That record only shows that an address (e.g., address A) was used at some point in the past—it doesn’t mean today’s payment page still requires address A.

Teaching example: Suppose the historical record is address A, and the currently trusted payment page shows address B. If two address strings differ by even one character, treat it as a mismatch. Similar beginnings, endings, and lengths don’t replace a full character-by-character comparison.

After copying, go back to the current payment page and confirm that the complete address exactly matches the withdrawal confirmation page character by character. If the confirmation page only shows the first and last few digits, or if the payment page refreshes or you switch and the address appears again, the historical record can’t be used to fill in the missing middle characters. If the addresses don’t match, don’t manually change one digit—go back to the trusted payment page and copy again.

Only when both pages can expand to show the full strings and they match character by character can you support the判断 「copied content is unchanged」. Now, place the current payment page and the withdrawal confirmation page side by side and check them—if they don’t match, copy again.
