I am aware this is from last November, but I did not see how you guys had implemented this until now. The UI and features are outstanding - congratulations, I think anyone would be able to use it!

Thanks!

PS: I didn't noticed I was in page 1, not in view all and just responded to the last post.

You can now use your Ledger Nano with Coinkite multisig wallets! Ledger Nano is a USB hardware wallet, which securely holds your private keys and now can be easily used to co-sign proposed shared Coinkite transactions.


Update! You can now use Ledger + Coinkite! Smart-cards with Multi-Signature for Even More Security

Update; We've added more info about our Offline Bitcoin Toolkit, it allows you to backup, sign transactions and generate any/all Coinkite multisig keys offline!

Quote

Back-up (Key Escrow), Generate Keys and Sign Transactions Offline

For additional security we offer theses downloadable files for use while off-line.

We provide this stand-alone, in-browser key generating tool, which creates a new random BIP32 ‘wallet’ to be your private key for the new wallet. The secret values that it picks are easy to print from the tool (for paper backup), and for storing on computers, we help you pick a secure passphrase and encrypt the file for you (using AES-256-CBC).

The resulting encrypted keyfile is verifiable, meaning if you have a little Unix background, you can be 100% sure that the key is encrypted using AES-256-CBC and with only your key.

Quote
Back-up and Key Escrow

The encrypted keyfile can be uploaded (one click) so that Coinkite can store it forever, and then we can decrypt it and use the key inside to authorize transactions very easily. The encrypted file can also be used offline without giving it to Coinkite if you wish.

Quote
Air Gap

Because we have delivered this “key generating” tool as a standalone Javascript/HTML file, you can use it on any computer with a browser. You can put the program onto a USB flash drive, and run it later, or on another computer or whatever. You do not have to trust us that we didn’t peek at your private key.

Updates: Building what you need!

http://blog.coinkite.com/post/126999568271/updates-building-what-you-need

We’ve been busy listening to our customers and building-out the “little things” that can make a big difference:

  • Flex Liquidity feature can now be controlled on a per-account basis. This means you can reduce or increase the number of “change back” coins you get in each transaction. Perhaps for a busy hot wallet, you want lots of change outputs, so there are always some confirmed balances in your account. In other cases, you might prefer to have fewer larger UTXO. Regardless, you now have the control! We recommend 3 change outputs for multisig accounts (because those transactions can be larger and slower due to extra signatures) and 10 change outputs for max flexibility in normal hot wallets.
  • Pay buttons can now be created by API call! We still encourage the use of JWT Tokens to set prices, descriptions and otherwise modulate the contents of payment buttons, but some customers need to link payment buttons to specific accounts and of course, we all love automation! Now it’s simple to create a payment button via our API.
  • Bitcoin Pay buttons, at your option, may now require a refund payment address from your customer. This was always optional before. Depending on your business and how you use our buttons, this change might give you a lot more confidence you won’t be left in a situation where you’re holding a customer’s money and can’t send it back to them.
  • Proposed, but incompletely-signed shared-account/multisig transactions, are now highlighted on balances page. Some of ourbusy customers would lose track of a proposed transaction that needed signing. Now they are in your face until you cancel or sign them.
  • Webhooks no longer follow redirect responses (302, 300) and your webhooks must be hosted on standard port numbers, such as 80 and 443. This fixes some obscure security risks.
