Security Best Practices

Wallet Security

When using Web3 wallets with UniVoucher:

  1. Verify the URL: Always ensure you're on univoucher.com before connecting
  2. Review Transactions: Carefully check all transaction details before signing
  3. Use Hardware Wallets: For large transactions, consider using a hardware wallet

Common Wallet Issues

Issue Solution
Wallet not connecting Refresh the page and try again
Network switch failing Manually switch in your wallet, then retry
Transaction stuck Check your wallet for pending transactions
Account not showing Ensure the account is active in your wallet
Mobile connection issues Try using WalletConnect or the wallet's built-in browser

Network Gas Fees

Each transaction on the blockchain requires gas fees:

  • Gas fees are paid in the native token of the network (e.g., ETH on Ethereum)
  • Fee amounts vary by network and current congestion
  • The connected wallet must have sufficient funds for gas
  • UniVoucher does not charge additional fees beyond the 1% card creation fee

Privacy Considerations

When connecting your wallet to UniVoucher:

  • Your wallet address becomes visible on the blockchain for transactions you perform
  • Cards you create are linked to your address on-chain
  • Your address is used to retrieve your created cards in the My Cards section
  • No personal information beyond your wallet address is collected or stored
  • No centralized database of user information
  • No KYC or identity verification required
  • Accessible to anyone, anywhere in the world
