Bitkit

• Name: Bitkit
• URL: https://bitkit.to/
• Category: mobile Bitcoin-Lightning wallet / self-custodial app-core-LSP stack
• Tags: bitcoin-ecosystem
• Summary: Bitkit is a self-custodial Bitcoin-and-Lightning mobile wallet built around a fairly opinionated stack, not a category anchor. The useful part is the shape: native iOS and Android shells over a shared Rust core, Blocktank-wired liquidity flows, LNURL support, and Trezor / Electrum integrations. Read it as a productized Blocktank wallet, not as the note that should anchor the broader wallet-control branch.
• What it does:
  • Ships as a self-custodial mobile wallet for Bitcoin onchain and Lightning payments
  • Splits the product across native iOS and Android apps that share a Rust core via FFI rather than a single thin cross-platform shell
  • Implements payment decoding and wallet flows around BOLT-11, BIP21, LNURL, Lightning Address invoicing, LNURL-auth, and LNURL withdraw / channel-request handling
  • Exposes Blocktank-backed Lightning Service Provider flows for order creation, channel opening and management, just-in-time channel creation, and gift-code redemption in the shared core
  • Supports Trezor hardware-wallet deep linking plus Electrum-backed account, address, UTXO, and transaction-signing workflows
  • Keeps explicit regtest, testnet, and mainnet build flavors for development, E2E testing, and production release work
• Key claims:
  • The official site positions Bitkit as a Bitcoin and Lightning wallet for Android and iOS and frames the product around self-custody rather than custodial convenience
  • The umbrella repository says Bitkit ships as native iOS and Android apps sharing a Rust core via FFI and points to the production repos for the app and core layers
  • The shared-core README shows scanner, LNURL, onchain, activity, Blocktank, and Trezor modules, which is much broader than a simple send / receive wallet surface
  • The core README explicitly lists support for BOLT-11, BIP21, LNURL, Lightning Address invoice generation, LNURL-auth, and Bitcoin address derivation across mainnet, testnet, and regtest
  • The Blocktank module documents LSP order creation, channel opening, just-in-time channel creation, and gift-code redemption, which is a strong signal that Bitkit packages Lightning liquidity operations into the wallet stack
  • The Trezor module documents deep-link integration plus Electrum-backed xpub, address, balance, UTXO, and signing flows, which reinforces that Bitkit is building a broader wallet-control-plane layer around the mobile app
• Whitepaper: No canonical Bitkit whitepaper or litepaper surfaced in this pass. The clearest current sources of truth were the official site plus the first-party umbrella, app, and shared-core repositories; see ../whitepapers/bitkit-primary-sources-2026-05-01.md.

Internal linkages

• Direct liquidity backend in the stack: blocktank
• Stronger mobile-Lightning anchors: phoenix-wallet and zeus

Control risk

• Practical leverage sits in Blocktank-dependent liquidity behavior, wallet-core defaults around payment and channel flows, and which hardware or backend integrations Bitkit chooses to keep first-class inside the app shell.
