BundleZeus is non-custodial — a fancy word that means we never hold your money, and your token’s owner key never leaves your browser. Here’s exactly how it works, including the one thing that is saved to our servers, and how to stay safe.

​
How your keys are handled

1

Wallets are made in your browser

When the app creates your buyer wallets, it makes them right on your device. The keys are created in your browser — not on our servers.
2

Everything is signed on your device

Every step of your launch — funding, turning on trading, and each buy — is approved (signed) on your device. What gets sent out is the finished, signed transaction, which is safe to send. It proves you approved it without ever revealing your key.
3

The server only gets signed transactions

To launch, our servers receive your signed transactions and public info (token address, network, amounts) — your token owner key is never sent. The only exception is the encrypted backup of your buyer wallets, described below (never your owner key).

​
Where your work is kept

  • Your working keys and draft live in your browser only, and are wiped when you close the tab.
  • Harmless settings (token address, amounts, network — never keys) can sync across your devices so you can pick up where you left off.
  • Signing in uses your wallet or a simple device key. No email, no password.

​
Backups of your buyer wallets

Losing 95 wallets would hurt, so BundleZeus gives you two safety nets:
  1. Download a backup file — a file with your wallet list (and keys) that you keep. Store it somewhere safe and offline.
  2. Encrypted backup — made automatically when your wallets are created. A scrambled (encrypted) copy of your buyer wallets is saved to your BundleZeus account so you can get them back from another device. This is the one place buyer-wallet keys leave your browser. Since it’s recoverable, treat it like any cloud backup — handy, but download your own file too if you want to be the only one who has them. Your token owner key is never part of this backup.
Your token owner key is on you. BundleZeus never stores it. If you lose it, nobody — including us — can get control of your token back.

​
What this protects you from

  • Server hacks — your owner key is never on the server, and the wallet backups are stored only as scrambled data, not usable keys
  • Us running off with your funds — we never take control of your token or its owner key; we can’t launch, give up ownership, or change your token without you
  • Phishing — because you approve every transaction in your own browser, you can check each one before you say yes

​
Stay-safe checklist

  • Download your wallet backup file and keep it offline
  • Never paste your owner key anywhere except the real BundleZeus app
  • Double-check you’re on the real bundlezeus.com before entering any key
  • Remember your browser clears everything when you close the tab — back up first
