## Status

Renamed: GreenAddress became Blockstream Green in March 2019, and Blockstream Green became the Blockstream app in May 2025.

## What is Blockstream app

The Blockstream app (formerly Blockstream Green, and before that GreenAddress) is a self-custodial Bitcoin wallet made by Blockstream. It covers on-chain bitcoin, Lightning and Liquid assets, runs on mobile and desktop, and can work with the Blockstream Jade hardware wallet.

## Who holds the keys

| Parameter | Details |
|---|---|
| Key control | Self-custodial: the app generates the private keys and stores them on the user's device. |
| Recovery | Funds can only be recovered with the backed-up recovery phrase if the device is lost or broken. |
| Account model | Optional 2FA multisig accounts: one key on the device, a second held by Blockstream and released only after a two-factor code. |
| Spending without Blockstream | In 2-of-2 accounts the device key alone can spend after a timelock (about a year on Bitcoin, about 45 days on Liquid); 2-of-3 accounts add a user-held backup key. |

## Features and supported networks

| Parameter | Details |
|---|---|
| Platforms | iOS, Android (Google Play and F-Droid), macOS, Windows and Linux. |
| Supported networks | On-chain bitcoin, Lightning and Liquid assets in one view. |
| Liquid assets | Through the Liquid Network the app supports tokenized assets such as L-BTC and USDT, with Confidential Transactions. |
| Buy / sell | Bitcoin can be bought in the app through integrated exchange partners. |
| Hardware wallet support | Works with the Blockstream Jade hardware wallet. |
| Multisig | 2-of-2 (2FA Protected) and 2-of-3 multisig accounts; 2FA by authenticator app, SMS, email or phone call. |

## Security and audits

- The app is open source; Blockstream describes it as 100% open-source software.
- The Android app's source code is published on GitHub under the GPL-3.0 licence.
- A 2FA multisig account needs both the device key and Blockstream's key to send, so a stolen phone or leaked recovery phrase alone cannot move those funds.
- An open-source recovery tool lets users of multisig accounts move coins without Blockstream's servers.

## History

| Date | Event |
|---|---|
| 27 July 2016 | Blockstream announced it had acquired the GreenAddress wallet. |
| 19 March 2019 | A rebuilt GreenAddress mobile wallet was released as Blockstream Green for Android and iOS. |
| 19 March 2019 | Blockstream said it would gradually retire the older Greenbits and GreenAddress wallets. |
| 29 May 2025 | Blockstream introduced the Blockstream app, built on the foundation of Blockstream Green. |

## Risks and caveats

- If the device is lost or broken and the recovery phrase was not backed up, the funds cannot be accessed.
- In 2FA Protected (2-of-2) accounts, spending needs Blockstream's server key until each deposit's timelock expires (about a year on Bitcoin by default).

## About the developer

- **Developer**: Blockstream
- **Founders**: GreenAddress was created by Lawrence Nahum, who joined Blockstream with the acquisition.

## How voting works

Votes are anonymous and carry no text. Each device has one vote per item; press the same button again to remove it. Cloudflare Turnstile checks that a person is voting. We keep a random device ID in a cookie and a salted hash of the IP address to limit abuse — no names, no accounts. Votes are visitors’ opinions, not investment advice.
