Wallet of Satoshi

• Name: Wallet of Satoshi
• URL: https://www.walletofsatoshi.com/
• Category: hybrid-custody Lightning wallet / Spark-backed self-custody shell / merchant receive add-on
• Tags: bitcoin-ecosystem
• Summary: Wallet of Satoshi is mostly a custody-mode comparison now. The product note matters because it straddles two very different stacks: a legacy custodial wallet in some regions and a Spark-wrapped self-custody shell elsewhere. Keep this note on the user-facing packaging; the named operator and legal perimeter that decides which mode appears where now lives in wallet-of-satoshi.
• What it does:
  • Ships a simple iOS and Android Bitcoin wallet for Lightning payments, with on-chain support and Lightning Address handling
  • Runs two modes: self-custody globally and custodial wallets only in select regions
  • Uses Spark for the self-custody path rather than extending the legacy custodial stack directly
  • Still sells convenience features around the wallet, including in-app bitcoin buys and a separate receive-focused POS app with LNURL and Bolt Card support
• Key claims:
  • This is not a Lightning control-plane anchor. It is a packaging note about custody mode, recovery posture, and who really controls the user path.
  • The important architectural move is the Spark dependency: self-custody here is not a homegrown Lightning stack, it is a wrapper around another network.
  • Regional custodial gating still matters because the operator decides where the old hosted wallet remains available and where the Spark route becomes the only path.
  • The POS shell is real but small. Keep the note for custody comparison and product packaging, not because Wallet of Satoshi became core merchant infrastructure.
• Whitepaper: No canonical standalone Wallet of Satoshi whitepaper or litepaper surfaced in this pass. The clearest current sources of truth were the official homepage, disclosure document, support articles, and POS page; see ../whitepapers/wallet-of-satoshi-primary-sources-2026-05-01.md.

Internal linkages

• Company / operator boundary for regional custody gating, support, and legal operating perimeter: wallet-of-satoshi.
• Strongest upward comparisons: phoenix-wallet and muun.
• Important dependency in the current product: spark.

Protocol / company boundary

• Keep this note on the product shell: simple Lightning UX, Spark-wrapped self-custody, recovery posture, and the small merchant / POS receive surface.
• Use wallet-of-satoshi for the named-operator layer around custody availability by region, custodial key management where offered, fee and balance-limit policy, privacy/compliance workflow, and packaged third-party rails.
• That split matters because what does the wallet app expose? and which company controls the custody mode and legal operating shell? are related but not identical questions.

Control surface

• At the product layer, the leverage sits in Spark dependence, recovery defaults, Lightning Address behavior, and the receive-side policy inside the small POS shell.

• The regional custody gate still matters here, but it now points upward to the company note because the practical authority is legal and operator-defined, not purely product-defined.

• Useful hybrid-custody packaging note. Still not a wallet-control anchor.
