Ethereum Address Has Uppercase and Lowercase Letters

Last updated: January 14th, 2021

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 mistype a letter or number, send it off, and it would be lost forever. If you use the checksummed version and mistype it, it will tell you that it's an invalid address.

For this reason, we warn you when your address is not checksummed. You can still send to it without issue but you should double-check the address before doing so, especially if you hand typed it.

Both addresses are exactly the same in how they work and can access your funds, except for the uppercase vs lowercase letters. Capitalization simply means the address has a checksum.

If you are sending to one of your own accounts, you can save the checksummed address via the settings page and copy the address displayed there.
