Multisig Native Assets CLI - User Guide

This document describes usage of Multisig Native Assets Client.

You can read more about native assets in the Cardano documentation.

Native Assets Client wraps the work of minting, transferring, and burning native assets on the Cardano blockchain the form of a java command-line tool. It also support the minting and burning with multiple signatures

Installation:

  • Download the latest version from the repository

  • Unzip it into a folder

  • Set clientId andapiKey at /conf/application.conf to the ones from Self Serve UI

  • Set network to preprod for testnet environment at /conf/application.conf (mainnet by default)

  • Set host, port for testnet or mainnet environments

  • Make native asset client executable

sudo chmod +x /bin/native-assets-client

  • Run client from the command line

./bin/native-assets-client -multisig -COMMAND

where COMMAND - one of the supported ones

Supported commands

  • createPolicy - Creates the policy context for minting, burning etc

  • getPolicy - Gets the policy by id

  • listPolicies - Lists the existing policies contexts

  • mint - Mints specific amount of new native assets with multisignature support

  • burn - Burns specific amount of native assets with multisignature support

  • transfer - Transfers new native assets to an address

  • addWitness - Add signature to the specified transaction id

  • listWitness - List all signatures that were added to the specified transaction id

  • sendTx - Sends transaction to the blockchain.

  • getTx - Get transaction stored in backend associated with policy Id

  • listTxs - List all transactions that are stored in backend

  • genVerKey - Generates verification key

  • genKeys - Generates an ED25519 key pair

  • genAddress - Generates a cardano enterprise address from public key
