Announcing Blockstream’s GreenAddress acquisition

Dear GreenAddress User,

Today, we have some exciting news. We are proud to announce that we are joining forces with Blockstream, a leader in open source blockchain technology.

For the last two years we have worked hard to bring you a user friendly, innovative, and safe bitcoin wallet. We couldn’t have come this far without you. No worries! Your wallet will continue to operate, and, as always: your funds are safe by design. We are grateful for your support and feedback. From the bottom of our hearts, thank you!

Many of you know that GreenAddress was one of the first bitcoin wallets to deliver features like HD multisig, hardware wallet support, dynamic fees, and transaction replacement. Now, with the expertise, experience, and resources of Blockstream, we will continue improving GreenAddress. Our goal is to remain at the forefront of innovation and deliver new improvements to our users.

Here’s a preview of upcoming improvements we are working on: a multi-platform wallet library to enable more rapid development of all platforms, enhanced privacy and security, and of course sidechain support throughout the platform. Extending GreenAddress to work with sidechains will mean you, as a GreenAddress user, will have the ability to manage not only bitcoin, but other assets and features that are coming online over the next months and years ahead as Blockstream and other developers establish new sidechain-based networks.

You could already experience the benefits of our collaboration with Blockstream: out of it came the novel and trustless nLockTime backup feature. Many other improvements are yet to come as a product of very exciting discussions we already had! We are extremely excited to solidify this relationship and continue evolving the space to the benefit of you and all our other valued users.

Wishing you all the best,
