I've been testing Copay and was pleasantly surprised how well it works. Since the latest version it 's one of the best wallets out there, and the support for all major platforms is a big plus. Kudos to team Copay!
One question though: I happen to run a firewall on my laptop, and whenever I open the Copay wallet, it wants to connect to bitpay.com and bws.bitpay.com. Why's that?
I assume (and hope) my wallet is stored locally, and only under my laptop's control. But when I refuse the connection, it won't open the wallet. Maybe it's just something trivial, but it would REALLY help in terms of independence and trustworthiness, if a local wallet would not rely on some extrernal 3rd party.
That's the server it connects to, to sync with blockchain and broadcast the transactions, since it is a lite wallet and doesn't downloads the whole blockchain.
