KeysArk

Back up your BIP39 recovery phrase

Your BIP39 recovery phrase is the master key to everything it protects — and a sticky note is no way to keep it. KeysArk stores it end-to-end encrypted, derived from a phrase only you hold, synced to your own cloud.

KeysArk speaks the standard: new vaults use a 24-word BIP39 phrase (256 bits of entropy) that you can import into MetaMask or any BIP39 wallet. Nothing proprietary to lock you in.

Why a vault beats paper or a screenshot

  • Encrypted with AES-256-GCM in your browser — a screenshot in your photos is plaintext.
  • Synced to your own Google Drive or Baidu netdisk, not a company database.
  • Exports carry a provenance manifest so you can still decrypt them years later.
  • Open source, so you can verify the phrase never reaches any server.

FAQ

Is it safe to store a recovery phrase online?

Only if it is encrypted before it leaves your device. KeysArk encrypts in your browser with a key derived from a phrase only you hold — the server stores ciphertext it cannot read.

Does KeysArk use standard BIP39?

Yes. New vaults generate a standard 24-word BIP39 phrase, importable into MetaMask or any BIP39-compatible wallet.

Can I still decrypt my backup years from now?

Yes. Every export embeds a provenance manifest recording the exact software and crypto spec that made it, so a future you can reproduce the environment and decrypt.

Is it free?

Yes — KeysArk is free and open source, with your encrypted backup stored in your own cloud drive.
