Nym CLI

This is a CLI tool for interacting with:

• the Nyx blockchain
• the smart contracts for the Mixnet

It provides a convenient wrapper around the nymd client with similar functionality to thenyxd binary for querying the chain or executing smart contract methods.

And in the future it will provide an easy way to interact with Coconut, to issue and verify Coconut credenitals.

It DOES NOT do these things:

The infrastructure components that run a gateway, mixnode or Service Provider have their own binaries.

The socks5 client also has its own binary, or use NymConnect.

Installing

Download the CLI binary for your platform from https://nymtech.net/downloads or get a specific version from GitHub releases.

Configuration

The Nym CLI runs against mainnet by default.

If you want to use another environment, you can do this by:

• providing a .env file
• setting environment variables (see here for options)
• passing named arguments

.env File

There are two ways to provide this:

1. A file called .env in the same directory as the binary
2. Pass the --config-env-file along with a command

Passing named arguments

You will need to pass the following with every command as an argument:

--mnemonic <MNEMONIC>                    
--nymd-url <NYMD_URL>                    
--mixnet-contract <MIXNET_CONTRACT_ADDRESS>      
--vesting-contract <VESTING_CONTRACT_ADDRESS>

How do I use it?

The simplest way to find out how to use the CLI is to explore the built-in help:

nym-cli --help
