SilentDragonLite CLI

silentdragonlite-cli is a command line SilentDragonLite light client. To use it, download the latest binary from the releases page and run ./silentdragonlite-cli or compile it yourself as documented below.

This will launch the interactive prompt. Type help to get a list of commands

Running in non-interactive mode:

You can also run silentdragonlite-cli in non-interactive mode by passing the command you want to run as an argument. For example, silentdragonlite-cli addresses will list all wallet addresses and exit. Run silentdragonlite-cli help to see a list of all commands.

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 SilentDragonLite-cli lightwalletd, and then run ./silentdragonlite-cli --server http://127.0.0.1:9067. You might also need to pass --dangerous if you are using a self-signed TLS certificate.

• The log file is in ~/.silentdragonlite/silentdragonlite-cli.debug.log. Wallet is stored in ~/.silentdragonlite/silentdragonlite-cli.dat

Note Management

silentdragonlite 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 2 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, silentdragonlite 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)

Compiling from source

Pre-requisites

• You need Rust and how you install it will depend on your version of Linux. Below are well known rust versions tested on common Linux distributions.

Linux Version	Rust Version Tested	Command to install
Ubuntu 18.04	1.47.0	USE RUSTUP
Ubuntu 20.04	1.57.0	sudo apt install rust-all
Debian 11	1.50.0	USE RUSTUP
Arch Linux	1.56.0	pacman -S rustc cargo

• Debian 11 comes with a much older rust compiler (1.48.0) and so you want to use rustup with Debian and install at least 1.50.0.
• If you're using another Linux distro, then consult their package manager for rustc and cargo, but if it's tool old then you want to use Rustup to install at least 1.50.0.
• The build will fail if you do not have rustfmt binary, which is included when you use rustup but may not be included in via operating system packages. Using rustup is recommended

To securely install rustup by compiling it yourself:

git clone https://github.com/rust-lang/rustup
cd rustup
cargo run --release

The above avoids piping the output of curl to bash (bad idea) and avoids using binaries. It will take a few minutes longer but is the better solution.

The compilation

Run the following commands to compile on your computer.

git clone https://git.hush.is/hush/silentdragonlite-cli
cd silentdragonlite-cli
cargo build --release
./target/release/silentdragonlite-cli

Or build with make

Alternatively, you can use the new makefile to build

make help
make build

Options

Here are some CLI arguments you can pass to silentdragonlite-cli. Please run silentdragonlite-cli --help for the full list.

• --server: Connect to a custom SilentDragonLite lightwalletd server.
  • Example: ./silentdragonlite-cli --server 127.0.0.1:9067
  • Example: ./silentdragonlite-cli --server lite.hush.is
• --seed: Restore a wallet from a seed phrase. Note that this will fail if there is an existing wallet. Delete (or move) any existing wallet to restore from the 24-word seed phrase
  • Example: ./silentdragonlite-cli --seed "twenty four words seed phrase"
• --recover: Attempt to recover the seed phrase from a corrupted wallet
• -n, --nosync: By default, Silentdragonlite-cli will sync the wallet at startup, so use this option to prevent the automatic sync at startup
