I wrote about multisig with different hardware wallets something more than a year ago. Back then It was awfully complicated and I didn’t really get it working.

Trezor BitCoin HardwareWallet

Today I received my Trezor BitCoin HardwareWallet. When I ordered it in June 2013, the expected delivery Date was October. But as it happens all that often with BitCoin related hardware, the dates get pushed back. They offered a device with plastic case for XBT 1 and one with an alloy case for XBT 3. … Continue reading »
