Guys, this isn't something the Dogecoin founders or the development team responsible for Dogecoin Core are involved in. You can of course jump into whatever projects you like, but please stop asking us about this.

There's work on sidechaining Doge & Ethereum, but that's not a new currency, it's using 1:1 mapped tokens on the Ethereum chain to represent Dogecoins, and they're fixed in value (there's a 1 Doge = 1 Doge joke here, but... seriously, 1 Doge = 1 Doge token in this case). The team working on that is still doing R&D and we don't have any estimated shipping date from them.
