Bitkit primary sources — 2026-05-01

Project status in this pass

  • No canonical standalone whitepaper or litepaper surfaced.
  • The clearest current source of truth is Bitkit’s official site plus its first-party GitHub repo network.

Primary-source snapshots

1) Official product site

  • URL: https://bitkit.to/
  • Key excerpt:
    • The homepage markets Bitkit as a Bitcoin and Lightning wallet for Android and iOS.
    • The hero line says users should not carry pocket money in someone else’s pocket, which is a clear self-custody framing.
    • The public web surface is sparse, so the repos matter disproportionately for recovering the real product shape.

2) Umbrella architecture repo

  • URL: https://github.com/synonymdev/bitkit
  • Key excerpt:
    • The umbrella repo says Bitkit ships as native iOS and Android apps that share a Rust core via FFI.
    • It points to distinct repos for bitkit-android, bitkit-ios, bitkit-core, vss-rust-client-ffi, and ldk-node.
    • That layout is a strong clue that Bitkit is a multi-layer wallet stack rather than a thin mobile client.

3) Shared core repository

  • URL: https://github.com/synonymdev/bitkit-core
  • Key excerpt:
    • The shared core README lists scanner support for BOLT-11, BIP21, and LNURL.
    • It also documents LNURL invoice generation, LNURL-auth, LNURL withdraw and channel-request helpers, Bitcoin address derivation and validation, and an activity/history layer.
    • The Blocktank module exposes Lightning Service Provider order creation, channel opening and management, just-in-time channels, and gift-code redemption.
    • The Trezor module exposes deep-link integration plus Electrum-backed account and signing workflows.

4) Android app repository

  • URL: https://github.com/synonymdev/bitkit-android
  • Key excerpt:
    • The Android repo confirms Bitkit now ships as a native Android app.
    • Build flavors explicitly map to regtest, testnet, and mainnet, and E2E flows can switch between local and network Electrum backends.
    • The repo references bitkit-docker for LNURL development testing and exposes Blocktank-specific Claude plugins for Lightning testing, which are unusually clear operating clues for a wallet project.

5) iOS app repository

  • URL: https://github.com/synonymdev/bitkit-ios
  • Key excerpt:
    • The iOS repo confirms a separate native iOS app with network selection tied to build configuration.
    • Debug builds default to regtest and release builds to Bitcoin mainnet, while E2E builds can target regtest or mainnet network backends.
    • This reinforces that Bitkit is built as a serious multi-environment wallet stack rather than just a consumer release artifact.

Working conclusion

Bitkit is best cataloged as self-custodial Bitcoin-and-Lightning wallet infrastructure with a native-app layer, shared Rust core, Lightning liquidity tooling, and hardware-wallet integration. The strongest evidence is the combination of official self-custody framing, explicit multi-repo architecture, LNURL and Bitcoin primitives in the core, Blocktank channel-management flows, and Trezor / Electrum integration details.
