@WilliamKingNoel-Bot WilliamKingNoel-Bot released this May 24, 2019


Program Platform Description
A CLI tool to start and interact with a wallet server. See Key Features below.
Auto-completion script for cardano-wallet
A commodity utility to launch a wallet server with a corresponding node backend.

This release brings full transaction support (on Byron network) to the API and the command-line. It also contains a few minor bug fixes and documentation improvements (as well as much more descriptive and user-friendly errors from the API and the command-line).

Key Features


  • A command-line interface which exposes the following features (see CLI manual below):

    • Create and Delete wallet
    • Get details of a particular wallet
    • List all known wallets
    • Generate BIP-39 mnemonic sentence (english) of various sizes
    • Update wallet metadata
    • Create and submit transactions from a single wallet
    • List known (used or unused) addresses of a wallet
  • A web server which exposes the following features (see API Documentation below):

    • Create and Delete wallet
    • Get details of a particular wallet
    • List all known wallets
    • Update wallet metadata & wallet encryption passphrase
    • Create and submit transactions from a single wallet
    • List known (used or unused) addresses of a wallet


  • A command-line interface which starts and supervise both a wallet server and a cardano-http-bridge

Known Limitations

  • ⚠️ Only one address derivation scheme is supported: sequential scheme (a.k.a. Icarus' address style or, addresses à la BIP-44).

  • ⚠️ So far, only one backend is supported: cardano-http-bridge (run on the Byron-OFT era, experimental stability).

  • ⚠️ The wallet backend server is shipped with only an in memory storage which is volatile: restarting the server will erase the memory completely.

Bug Fixes

Ticket Title
#291 Shuffle statistical tests sometimes fail...

Known Issues

Ticket Title
#250 GET v2/wallets does not list wallets from oldest to newest
#324 Bech32 occassionally fails when decoding a string with an omitted character
#326 Cannot post transaction after updating wallet's passphrase

Installation Instruction

Please note that currently only Unix\Linux platform is supported.

  1. Install cardano-http-bridge.

    • Install the rust toolchain.
    • In terminal run cargo install --git
    • make sure $HOME/.cargo/bin is on your $PATH
  2. Download cardano-wallet and cardano-wallet-launcher and put it in the directory that is on your $PATH, e.g. /usr/local/bin. Make sure to add exec permissions on binary files:

    • chmod u+x cardano-wallet cardano-wallet-launcher
  3. Start cardano-wallet-launcher --help and see available parameters and follow instructions about how to install cardano-http-bridge if you haven't done already in point 1.

⚠️ The wallet server & launcher both expect a NETWORK ENV var to be available with one of the following value:

  • mainnet
  • testnet
  • staging (not supported)

This variable commands which network the software should connect to and interact with.
