@bsv/wallet-toolbox-mobile

Mobile build of @bsv/wallet-toolbox — the reference BRC-100 wallet implementation. Same wallet, signer, services, and monitor APIs as the full package, trimmed for React Native and other mobile runtimes: no Knex, no SQLite/MySQL native bindings, no Node-only IO.

Use this package in:

• React Native apps
• Capacitor / Cordova mobile apps
• Any other runtime that lacks Node native modules but provides IndexedDB or remote HTTP

For Node servers, use @bsv/wallet-toolbox. For browsers, use @bsv/wallet-toolbox-client.

Install

npm install @bsv/wallet-toolbox-mobile

Peer dependency: @bsv/sdk.

Quick start

import {
  Wallet,
  WalletSigner,
  WalletStorageManager,
  StorageClient,
  Services,
} from '@bsv/wallet-toolbox-mobile'
import { KeyDeriver, PrivateKey } from '@bsv/sdk'

const chain = 'main'
const keyDeriver = new KeyDeriver(new PrivateKey(privateKeyHex, 'hex'))

// Remote storage over HTTP is the default mobile-safe backend.
const storageManager = new WalletStorageManager(keyDeriver.identityKey)
await storageManager.addWalletStorageProvider(
  new StorageClient(keyDeriver, 'https://storage.example.com')
)
await storageManager.makeAvailable()

const services = new Services(chain)
const signer = new WalletSigner(chain, keyDeriver, storageManager)
const wallet = new Wallet(signer, services)

const { tx } = await wallet.createAction({
  description: 'mobile send',
  outputs: [{ satoshis: 1000, lockingScript: recipientScript }],
})

Use cases

Self-custody BSV wallet on a phone

Run the BRC-100 wallet entirely on-device, with remote storage for cross-device sync.

Companion-app signer for a desktop wallet

Use mobile as the signer over a paired channel while a desktop runs the heavier services.

Receive-only mobile app

Spin up a minimal wallet that watches for inbound payments via a remote storage backend.

What's excluded vs @bsv/wallet-toolbox

Wallet, WalletSigner, WalletStorageManager, StorageClient, StorageIdb, Services, Monitor, WalletPermissionsManager, WalletSettingsManager, key management, and MockChain are all included.
