Welcome to the Electroneum Wallet Manager. Creating an account will automatically create you an Electroneum mobile wallet. You'll be able to access your mobile wallet via the Electroneum App on Android using the same log in details you use here.
If you only use the Electroneum app or my.electroneum.com you are safe to ignore this.
If you run your own Electroneum node, you MUST update to our latest codebase on GitHub before May 30th. As of block 307500, you MUST have updated.
Read the documentation to find out what enhancements these changes will bring to Electroneum.
