Running using a Ledger device (BETA)

It's possible to use a Ledger device via the Zondax app. To do so, invoke the cli with --ledger, in addition to any other flags you wish to use. Do note that not all functionality is available, namely encrypting the wallet data, exporting or importing secret keys and addresses. The main thing to keep in mind when using a ledger device is that signing keys never leave the device, and for privacy viewing keys are not stored between sessions. Additionaly, some actions may require to be confirmed on the device, but this isn't signalled by the cli.

Currently interacting with the device is necessary when:

• generating sapling addresses (IVK and OVK
• starting up the wallet (for the above reason)
• sending funds, to review transaction details
• while syncing, to retrieve nullifiers

Privacy

• While all the keys and transaction detection happens on the client, the server can learn what blocks contain your shielded transactions.
• The server also learns other metadata about you like your ip address etc...
• Also remember that t-addresses don't provide any privacy protection.

Notes:

• If you want to run your own server, please see zecwallet lightwalletd, and then run ./zecwallet-cli --server http://127.0.0.1:9067.
• The log file is in ~/.zcash/zecwallet-light-wallet.debug.log. Wallet is stored in ~/.zcash/zecwallet-light-wallet.dat

Note Management

Zecwallet-CLI does automatic note and utxo management, which means it doesn't allow you to manually select which address to send outgoing transactions from. It follows these principles:

• Defaults to sending shielded transactions, even if you're sending to a transparent address
• Sapling funds need at least 5 confirmations before they can be spent
• Can select funds from multiple shielded addresses in the same transaction
• Will automatically shield your transparent funds at the first opportunity
  • When sending an outgoing transaction to a shielded address, Zecwallet-CLI can decide to use the transaction to additionally shield your transparent funds (i.e., send your transparent funds to your own shielded address in the same transaction)
