An iOS and Android Bitcoin payment wallet with Lightning support and region-dependent custodial or Spark self-custody modes.
Wallet of Satoshi focuses on mobile payments: scan or paste a Lightning invoice or Bitcoin address, then review the payment before confirming. The custody mode matters. Custodial accounts use provider-held keys and email recovery. Spark self-custody accounts leave backup responsibility with the user. Availability, fees and recovery options differ between modes; check the app's selected mode and current quote before moving funds.
Source-checked information, not a security audit. Details can differ by product mode and region.
The provider holds the wallet keys. Availability depends on the user's region.
The self-custody option uses Spark and leaves keys with users. Its operating assumptions differ from running a personal Lightning node.

Supports Lightning payments in both custody models. The self-custody implementation uses Spark; this is not evidence that the user runs a personal Lightning node or manages channels.
Custodial recovery uses the account email. In self-custody mode, users must protect their own wallet backup; losing recovery material can mean losing access to funds.
Lightning routing costs vary. Bitcoin top-ups and on-chain sends carry service fees, and on-chain pricing differs by custody mode. Spark can add infrastructure fees. Review the disclosure and transaction quote rather than assuming payments are free.
The app selects an eligible custody mode by region. Custodial service is region-limited; self-custody still depends on legal eligibility and third-party network conditions. Stablecoin features have separate jurisdiction restrictions.
