description

This skill should be used when setting up a 1Sat wallet, creating a new wallet instance, syncing addresses, configuring storage, or restoring from backup. Triggers on 'create wallet', 'setup wallet', 'initialize wallet', 'sync wallet', 'restore wallet', 'wallet backup', 'address sync', 'wallet storage', 'IndexedDB wallet', 'SQLite wallet', 'BRC-100 wallet', 'wallet factory', 'remote wallet', or 'full sync'. Uses @1sat/wallet, @1sat/wallet-node, and @1sat/wallet-remote packages. Note: @1sat/wallet-browser is deprecated in favor of @1sat/wallet-remote.

Wallet Setup

Create, configure, and sync 1Sat wallets for Node.js, browser, or remote environments.

Packages

Package	Environment	Storage
@1sat/wallet-node	Node.js / Bun	SQLite (Knex) or MySQL
@1sat/wallet-remote	Any (thin client)	Remote server only
@1sat/wallet	Core library	Indexers, backup, address sync
@1sat/wallet-browser	Deprecated	Use @1sat/wallet-remote instead

Node.js Wallet

import { createNodeWallet } from '@1sat/wallet-node'

const { wallet, services, monitor, destroy, fullSync } = await createNodeWallet({
  privateKey: 'L1...', // PrivateKey instance, WIF string, or hex string
  chain: 'main',       // 'main' | 'test'
  storageIdentityKey: 'my-cli-agent', // unique per device, persist across sessions
  // Optional:
  storage: {           // Knex.Config — default: SQLite at ./wallet.db
    client: 'mysql2',
    connection: { host: '127.0.0.1', user: 'root', password: '...', database: 'wallet' },
    useNullAsDefault: true,
  },
  remoteStorageUrl: 'https://storage.example.com', // enables cloud backup
  feeModel: { model: 'sat/kb', value: 100 },       // default shown
  onTransactionBroadcasted: (txid) => console.log('Broadcast:', txid),
  onTransactionProven: (txid, blockHeight) => console.log('Proven:', txid, blockHeight),
})

// Monitor handles tx lifecycle (broadcasting, proof checking)
// It is created but NOT started — call startTasks() when ready
monitor.startTasks()

// When done: stops monitor, destroys wallet, closes database
await destroy()

NodeWalletResult

Property	Type	Description
wallet	Wallet	BRC-100 wallet instance
services	OneSatServices	1Sat API access
monitor	Monitor	Transaction lifecycle monitor (call startTasks())
destroy	() => Promise<void>	Cleanup: stops monitor, destroys wallet, closes DB
fullSync	((onProgress?) => Promise<FullSyncResult>) | undefined	Only available if remoteStorageUrl was provided and connected
storage	WalletStorageManager	For diagnostics
remoteStorage	StorageClient | undefined	For diagnostics

Remote Wallet

No local storage. The server handles transaction lifecycle.

import { createRemoteWallet } from '@1sat/wallet-remote'

const { wallet, services, destroy, feeModel } = await createRemoteWallet({
  privateKey: 'L1...',
  chain: 'main',
  remoteStorageUrl: 'https://my-wallet-server.example.com',
  // Optional:
  feeModel: { model: 'sat/kb', value: 100 },
  connectionTimeout: 5000, // default: 5000ms
})

RemoteWalletResult has no monitor or fullSync — the server manages those. It includes feeModel indicating the effective fee model used.

Full Sync (Multi-Device Handoff)

fullSync reconciles local and remote storage. It pushes local changes, resets sync state, then pulls everything from the server. This runs automatically during wallet creation when another device is active, or can be called manually via the fullSync property on the wallet result.

// Only available if remoteStorageUrl was provided and connected
if (fullSync) {
  const result = await fullSync((stage, message) => {
    console.log(`${stage}: ${message}`)
  })
  console.log('Pushed:', result.pushed) // { inserts, updates }
  console.log('Pulled:', result.pulled) // { inserts, updates }
}

FullSyncOptions (internal)

The standalone fullSync() function takes { storage, remoteStorage, identityKey, onProgress?, maxRoughSize?, maxItems? }. The factory functions wrap this for you.

FullSync Stages

Stage	Description
pushing	Pushing local data to remote server
resetting	Resetting sync state for clean pull
pulling	Pulling all data from remote
complete	Sync finished

Derivation Paths

import {
  YOURS_WALLET_PATH, YOURS_ORD_PATH, YOURS_ID_PATH,
  getKeysFromMnemonicAndPaths, deriveIdentityKey,
} from '@1sat/utils'

Constant	Path	Purpose
YOURS_WALLET_PATH	m/44'/236'/0'/1/0	Yours Wallet payment
YOURS_ORD_PATH	m/44'/236'/1'/0/0	Yours Wallet ordinals
YOURS_ID_PATH	m/0'/236'/0'/0/0	Yours Wallet identity
RELAYX_ORD_PATH	m/44'/236'/0'/2/0	RelayX ordinals
RELAYX_SWEEP_PATH	m/44'/236'/0'/0/0	RelayX sweep
TWETCH_WALLET_PATH	m/0/0	Twetch payment
AYM_WALLET_PATH	m/0/0	AYM payment
AYM_ORD_PATH	m	AYM ordinals (master key)

// Derive keys from mnemonic
const keys = getKeysFromMnemonicAndPaths(mnemonic, {
  changeAddressPath: YOURS_WALLET_PATH,
  ordAddressPath: YOURS_ORD_PATH,
  identityAddressPath: YOURS_ID_PATH,
})
// keys.payPk (WIF), keys.ordPk (WIF), keys.identityPk (WIF)

// Derive identity key from pay + ord WIFs
const identityKey = deriveIdentityKey(keys.payPk, keys.ordPk)

Address Sync

Address sync uses a fetcher/processor split for Chrome extension compatibility (SSE does not work in service workers). Use AddressSyncManager in unified environments.

import { AddressSyncManager, AddressSyncQueueIdb } from '@1sat/wallet'

const syncManager = new AddressSyncManager({
  wallet,
  services,
  syncQueue: new AddressSyncQueueIdb(), // or AddressSyncQueueSqlite
  addressManager,                        // AddressManager instance
  network: 'mainnet',                    // 'mainnet' | 'testnet'
  batchSize: 20,                         // optional, default 20
})

syncManager.on('sync:progress', ({ pending, done, failed }) => {
  console.log(`Pending: ${pending}, Done: ${done}, Failed: ${failed}`)
})

await syncManager.sync() // opens SSE stream + processes queue
syncManager.stop()

For Chrome extensions, use AddressSyncFetcher (popup context) and AddressSyncProcessor (service worker) separately.

Backup & Restore

Backup uses a streaming Zip-based API via fflate. FileBackupProvider implements WalletStorageProvider to receive sync chunks during export.

import { FileBackupProvider, FileRestoreReader, Zip, ZipDeflate, unzip } from '@1sat/wallet'

// === BACKUP ===
const chunks: Uint8Array[] = []
const zip = new Zip((err, data, final) => {
  if (err) throw err
  chunks.push(data)
  if (final) {
    const blob = new Blob(chunks, { type: 'application/zip' })
    // save or download blob
  }
})

const provider = new FileBackupProvider(zip, storage.getSettings(), identityKey)
await storage.syncToWriter(auth, provider)
// Write manifest.json to zip, then zip.end()

// === RESTORE ===
const zipData = new Uint8Array(await file.arrayBuffer())
const unzipped = await new Promise<Unzipped>((resolve, reject) => {
  unzip(zipData, (err, data) => (err ? reject(err) : resolve(data)))
})
const manifest = JSON.parse(new TextDecoder().decode(unzipped['manifest.json']))
const reader = new FileRestoreReader(unzipped, manifest)
await storage.syncFromReader(manifest.identityKey, reader)

Wallet Indexers

These run automatically during address sync. No configuration needed.

Indexer	What it tracks
InscriptionIndexer	Ordinal inscriptions
Bsv21Indexer	BSV-21 fungible tokens
OrdLockIndexer	Marketplace listings
LockIndexer	Time-locked BSV
MapIndexer	MAP protocol metadata
SigmaIndexer	Sigma protocol signatures
OriginIndexer	Ordinal origin tracking
OpNSIndexer	OpNS name bindings
CosignIndexer	Cosigner data
FundIndexer	Funding outputs (P2PKH)

Installation

bun add @1sat/wallet-node    # Node.js / Bun
bun add @1sat/wallet-remote  # Remote (thin client)
# @1sat/wallet-browser is deprecated — use @1sat/wallet-remote instead

All environment packages depend on @1sat/wallet (core) which provides indexers, backup, and address sync.

Hardware Key Protection: @1sat/vault

On macOS arm64, private keys can be protected by the Secure Enclave via @1sat/vault. Keys are encrypted with a hardware-bound P-256 key (CryptoKit ECIES: ECDH + HKDF-SHA256 + AES-256-GCM) and never leave the chip. All decryption requires Touch ID via LAContext.

import { protectSecret, unlockSecret, listSecrets, isSupported } from '@1sat/vault'

// Check availability
if (await isSupported()) {
  // Encrypt and store a WIF key
  await protectSecret('my-wallet-key', wifString)

  // Retrieve (triggers Touch ID)
  const wif = await unlockSecret('my-wallet-key')

  // List stored secrets
  const secrets = await listSecrets()

  // Remove
  await removeSecret('my-wallet-key')
}

• Package: @1sat/vault@0.0.1 (npm)
• Vault directory: ~/.secure-enclave-vault/
• Platform: macOS arm64 only (fails informatively elsewhere)
• No entitlements, no code signing, no .app bundle needed
• Used by BAP CLI (bap touchid enable) and ClawNet CLI (clawnet setup-key)

Alternative: CLI Setup

For quick wallet setup without writing code, use @1sat/cli:

# Run directly — no install needed
bunx @1sat/cli init

# Optional: install globally for frequent use
bun add -g @1sat/cli
# Then use the short form: 1sat init

The CLI stores configuration in ~/.1sat/ and supports key management via PRIVATE_KEY_WIF env var or encrypted keystore at ~/.1sat/keys.bep. See the 1sat-cli skill for full CLI documentation.
