BlueWallet

• Name: BlueWallet
• URL: https://bluewallet.io/
• Category: bitcoin wallet-control-plane / watch-only and PSBT hardware-wallet infrastructure / optional self-hosted Lightning-and-node connectivity stack
• Tags: bitcoin-ecosystem
• Summary: BlueWallet is better cataloged as a bitcoin wallet-control plane than as a simple mobile wallet app. Its official materials jointly expose self-custodial onchain wallets, watch-only cold-storage views, multisig vaults, PSBT signing flows for hardware wallets, optional connection to a user’s own Bitcoin node, and optional Lightning accounts tied to the user’s own LNDhub setup. That mix makes BlueWallet look like a broad operating layer for self-custodial Bitcoin and Lightning workflows rather than only a spend-and-receive wallet UI.
• What it does:
  • Provides self-custodial Bitcoin and Lightning wallets for iOS and Android, with private keys staying on-device
  • Supports watch-only wallets by importing public addresses, xpubs, or ypubs so users can monitor cold storage without exposing spending keys
  • Exposes multisig vault and PSBT-centered hardware-wallet workflows, including explicit Coldcard and Cobo Vault support plus generic hardware-wallet mode
  • Lets users connect BlueWallet to their own Bitcoin full-node stack through Electrum Personal Server, ElectrumX, or Electrs instead of relying only on public infrastructure
  • Supports a Lightning setup tied to the user’s own node through LNDhub, which BlueWallet positions as useful for family wallets, small communities, or groups running their own node
  • Adds advanced wallet-operations features such as coin control, Payjoin, custom entropy, LNURL, multiple encrypted storages, plausible deniability, and a Lightning browser / marketplace layer
• Key claims:
  • The homepage says BlueWallet offers watch-only wallets, multisig vaults, Lightning wallets, notifications, plausible deniability, and transaction controls such as fee choice, bumping, cancelling, and batching
  • The README says BlueWallet is a “Thin Bitcoin Wallet” built with React Native and Electrum, that private keys never leave the device, and that Lightning, SegWit, Replace-By-Fee, encryption, and plausible deniability are all supported
  • The watch-only page says users can import a public address, xpub, or ypub and monitor cold storage or a paper wallet without touching the private key
  • The Lightning page says BlueWallet can connect to a user’s own node via LNDhub, with Lightning accounts associated to that node, and explicitly frames that setup as useful for families, communities, or groups running their own node
  • The features page says BlueWallet supports coin control, Payjoin, plugging into a user’s own Bitcoin full node through EPS / ElectrumX / Electrs, PSBT-based hardware-wallet workflows, multiple encrypted storages, LNURL, a Lightning browser, and a marketplace of Lightning-enabled apps
  • The support docs taxonomy shows BlueWallet maintains first-party guides for offline signing, Coldcard integrations, Cobo Vault, multisig vault creation and spending, and self-hosted LNDhub deployment on Ubuntu, macOS, and RaspiBolt
• Whitepaper: No canonical standalone BlueWallet whitepaper or litepaper surfaced in this pass. The clearest current sources of truth were the official site, feature pages, support taxonomy, and public repository; see ../whitepapers/bluewallet-primary-sources-2026-05-01.md.

Internal linkages

• Best upward comparison points for self-custody coordination and operator-grade wallet workflow: sparrow-wallet and nunchuk.

• Keep this note out of broader custody or privacy branches unless the point is specifically BlueWallet’s watch-only, PSBT, or self-hosted node workflow.
