Xahau SmartWallet Guardian

Protect your Xahau wallet from accidental or high-value outgoing payments

SmartWallet Guardian is a lightweight security tool built for Xahau Mainnet.
Once installed, it prevents your wallet from sending more than 100 XAH in a single transaction — without needing any coding or technical setup.
This reduces the risk of:
Accidental large transfers
– Misclicks or typing errors
– Scam-initiated high-value withdrawals
– Human mistakes when signing transactions

🔒 What SmartWallet Guardian Does

✔ Blocks outgoing payments above 100 XAH
✔ Allows outgoing payments up to 100 XAH
✔ Always accepts incoming payments
✔ Runs automatically once installed
✔ Works fully on Xahau Mainnet
✔ No app installation required
✔ Uses Xahau Hooks technology

🌐 Why SmartWallet Guardian?

Most crypto wallets will send any signed transaction — even if:

  • You typed one extra zero
  • You selected the wrong address
  • Someone tricked you into sending too much

SmartWallet Guardian adds one more layer of protection without needing external apps or custodial services.

If you can sign a normal transaction, you can install this protection.
