SPW Wallet

Tracking since May 8, 2026.

  description

  SPW Wallet is a self-custody wallet for the SPW network, built as a Chrome extension.
  Everything happens inside the extension popup — there is no website to redirect to,
  no remote code, no dApp integration in this release.
  
  WHAT IT DOES
  • Create a new wallet — generates a 12-word BIP-39 recovery phrase locally, then
    encrypts your keys with a password using PBKDF2 (600,000 iterations) and AES-GCM.
    The encrypted vault is stored in chrome.storage.local; the password is never sent
    anywhere.
  • Import an existing wallet from a 12 or 24-word BIP-39 phrase.
  • Show your address with a QR code for receiving SPW.
  • Show your current balance, queried from the SPW node REST API.
  • Send SPW to any address, with optional 80-byte memo. The transaction is signed
    locally with secp256k1 and broadcast to the SPW node's /tx/broadcast endpoint.
  • Browse your transaction history.
  • Reveal your recovery phrase (password-gated, with auto-clearing clipboard).
  • 15-minute idle auto-lock; locks immediately on browser close.
  
  WHAT IT DOES NOT DO
  • It does not collect, transmit, or analyze any user data.
  • It does not load any remote code — all JavaScript executes from the bundle inside
    this extension.
  • It does not inject scripts into web pages and does not interact with dApps in this
    release. (dApp integration may come in a future version, with explicit user
    approval flows.)
  • It does not support tokens other than SPW.
  • It does not require an account, sign-up, or any external service.
  
  PRIVACY
  • Zero data collection. The only network traffic is between this extension and the
    SPW node REST API at https://spw.network/api, used to fetch your balance, list
    transactions, and broadcast signed transactions.
  • Full privacy policy: https://spw.network/privacy
  
  TECHNICAL
  • Manifest V3. Chromium-based browsers, Chrome 102+.
  • All cryptography runs in-browser using @noble/secp256k1 (signing), @noble/hashes
    (sha-256, ripemd-160, hmac, sha-512), @scure/bip39 (mnemonic), and qrcode (the
    receive-screen QR code). These libraries are bundled into the extension; no
    remote loading.
  • Encryption: PBKDF2-SHA256 (600k iterations) → AES-256-GCM, via the browser's
    built-in SubtleCrypto.
  • Source code: https://github.com/otisaipro/spw-wallet

  WHAT'S NEW IN 1.0.1
    • Multi-wallet support: create or import additional wallets, switch from the header dropdown, rename or remove individual wallets — all gated by one master password.
