With Ledger’s low level and high level APIs, integration of third-party services can be achieved quite easily.
To celebrate our five major partnerships, we decided to release a limited edition of the HW.1 with the liveries of GreenAddress, Mycelium, Coinkite , Copay and Electrum.
The HW.1 limited editions use the design of the selected service, and are shipped in a box containing a security card, instructions, and a recovery sheet. They are available worldwide for 15.00€ (+20% VAT is you are in Europe) and with a free shipping option.
