History & Background

Backpack was founded by Armani Ferrante (ex-Solana Labs) and launched in 2022. It introduced xNFTs — executable NFTs that run apps directly inside the wallet. It later added Ethereum support and became a popular alternative to Phantom among Solana power users.

WalletGuard tracks every official release of Backpack and cross-references download hashes against the developer-signed artifacts so you can verify what you install.

Who should use Backpack

Best for: Solana power users and xNFT enthusiasts who want an extensible wallet experience with multi-chain support.

Custody type: Self-custody

Risk profile: Closed-source wallet. Verify extension ID carefully as it is a common target for clones.

Self-custody notice: Backpack is a hot wallet. Your keys are stored locally on your device or browser. For large holdings, consider pairing with a hardware wallet. Never share your seed phrase with anyone.

Common scam patterns targeting Backpack users

  • Fake browser extension clones with a near-identical name or icon, distributed through search ads.
  • Phishing websites mimicking backpack.app with a typo or subdomain.
  • Social media accounts impersonating Backpack support and requesting seed phrases.
  • Modified installers distributed on file-sharing sites or Telegram channels claiming to offer an "early version".

Pre-install security checklist

  • Verify you are on the correct official domain: backpack.app
  • Compare SHA-256 hash of your download against the values on this page before running anything.
  • Check that the version number matches the latest release listed here (v1.34.3).
  • Never enter your seed phrase anywhere except the wallet application itself.
  • For significant holdings, use a hardware wallet for signing instead of a hot wallet.
