Coinbase - Ethereum wallet

On Thursday, Ethereum hit another business milestone when Coinbase, the leading mainstream platform for buying and trading of bitcoin, added support for ether. Coinbase customers—there are 4 million of them in 32 countries—can now easily buy and trade ether using the Coinbase web site or mobile app.
Still, many in the cryptocurrency world say ether is even more exciting than bitcoin because of its potential for storing smart contracts on the Ethereum network. Many developers are already running early-stage apps on top of Ethereum, for all manner of services including blockchain payments via Slack and placing bets on which tech startups will get popular first.

Coinbase had already added ether to its more formal cryptocurrency exchange site for institutional investors, GDAX, back in May. “We saw individual as well as developer interest in Ethereum rise at the end of 2015, and by the early part of 2016 our customers on GDAX were saying, ‘Give us the ability to sell ether,'” says Adam White, VP of business development and strategy for Coinbase. Bringing ether to the mainstream product was the obvious next step.

Coinbase adding ether also means that all partners using the Coinbase “buy widget” can do the same. One such partner is Lawnmower, a mobile app that originally launched as a “roundup” service that invests your spare change into bitcoin, using Coinbase.
