Blockstream's verified channels span X (@Blockstream, @BlockstreamHelp, plus product-specific accounts), Telegram, Discord, GitHub, Reddit (r/blockstream), Nostr, Instagram, TikTok, and YouTube. Blockstream employees will never DM you first on Telegram, Discord, or any messaging app, so treat anyone who does as an impersonator. For account-specific issues involving personal information, submit a Help Center ticket rather than reaching out over social DMs.

Blockstream's "Help Us Improve" analytics is opt-in, and no data is shared with third parties. It links app interactions to an opaque, unguessable identifier, never to your wallet, keys, addresses, balances, or transactions. The data it does collect (language, country, button presses, load times, OS and app version) is AES256-encrypted, deleted after two years, and timed deliberately imprecisely so usage can't be tied to on-chain events. You can disable it anytime through the "Help Us Improve" setting.

The app generates your recovery phrase using the BIP39 standard (12 words by default, or 24, drawn from a fixed 2,048-word list) and derives your wallet's keys with the BIP32 hierarchical deterministic standard. Singlesig wallets can be restored in other BIP39-compatible software such as Electrum, but wallets created with two-factor authentication use a multisig security model and can only be restored in the Blockstream app.

The Blockstream app is a "hot" software wallet: it stores your private keys on your internet-connected phone or computer, leaving them exposed to malware, phishing, deceptive download links, OS vulnerabilities, and device theft. Jade is "cold" storage, keeping keys offline and signing transactions internally, so there is nothing of value to extract even if your computer is compromised. Use the app for small everyday amounts and Jade for long-term storage of significant holdings.

A recovery phrase is a list of 12 or 24 BIP39 words that holds everything needed to restore your wallet, your private key in human-readable form. Blockstream never keeps a copy, so backing it up is your responsibility: store it offline (metal is more disaster-proof than paper), keep it completely secret, and never type or send it over any internet-connected channel. Anyone who gets your recovery phrase can take your funds, and Blockstream support will never ask for it.

The app generates a new, unused address every time you receive, which is standard Bitcoin best practice for privacy: reusing one address lets anyone watching the public blockchain link your payments together. Every address belongs to the same wallet, and older addresses keep working, so bitcoin sent to a previous address still arrives without issue. The app handles this automatically, so you get the privacy benefit with no extra steps.

Bitcoin blocks are mined roughly every ten minutes on average, but the timing is unpredictable, and miners prioritize transactions paying higher fees since block space is limited. If yours is stuck behind a backlog, you can increase the fee to move it toward the front of the line. High-value transactions are typically considered settled after six confirmations; for faster, more predictable everyday payments, Liquid and Lightning are alternatives.

Every network has limited block space, so fees decide whose transaction gets prioritized. Bitcoin mainnet fees are the highest and can spike (historically $20 or more) when demand surges from price moves or new token systems like Ordinals and Runes; the app's fee figures are estimates, and you can raise the fee to speed up a slow transaction. Liquid fees are far lower with one-minute blocks, and Lightning fees, based on payment amount rather than data size, are lower still.
