Ok I will bring my concern here so that anyone can look up to.
In my whole history of doing transaction, this is the first time I encountered the noticed. Im trying to send SDRN to Cryptopia and after getting the deposit address provided by Cryptopia, I paste it on MEW and suddenly that noticed appear.
According to note:
There are two versions of Ethereum addresses: one that contains uppercase letters and one that does not:
0x7cb57b5a97eabe94205c07890be4c1ad31e486a8
0x7cB57B5A97eAbe94205C07890BE4c1aD31E486A8
The one that is all lowercase is "not checksummed" meaning that you could mis-type a letter/number and it send it off and it would be lost forever. If you use the checksum'd version and mis-type it, it will tell you that it's an invalid address.
For this reason, we warn you when you address is not checksummed. You can still send to it without issue but if you should double-check the address before doing so, especially if you hand-typed it.
If you are sending to one of your own wallets, you can save the checksummed address via the "View Wallet Info" page and copying the address displayed there.
Both addresses are exactly the same, except for the uppercase vs lowercase letters. Capitalization simply means the address has a checksum. Both will work exactly the same and have your funds.
Just need feedbacks from the community on what you can say about this? So that I can have such idea on future transaction.
