Disclaimers

There are some known areas for improvement:

  • This app depends upon related libraries that it uses. There may be bugs.
  • The wallet only supports transactions between shielded Z-addresses, rendering it incompatible with wallets that cannot send to supported shielded pools.
  • Similar to other cryptocurrency wallets, traffic analysis can potentially compromise user privacy.
  • The wallet relies on the lightwalletd server to provide accurate transaction information, necessitating trust in the server.
  • This app has been developed and run exclusively on mainnet and may not function correctly on testnet.

For more information regarding the security and privacy limitations of the wallet, please refer to the Wallet App Threat Model.
