Daedalus

Daedalus - Cryptocurrency Wallet

Installation

Yarn

Yarn is required to install npm dependencies to build Daedalus.

Nix

Nix is needed to run Daedalus in nix-shell.

1. Install nix: curl -L https://nixos.org/nix/install | sh (use sh <(curl -L https://nixos.org/nix/install) --darwin-use-unencrypted-nix-store-volume on macOS Catalina)
2. Employ the signed IOHK binary cache:

   $ sudo mkdir -p /etc/nix
   $ sudo vi /etc/nix/nix.conf       # ..or any other editor, if you prefer

   and then add the following lines:

   substituters = https://hydra.iohk.io https://cache.nixos.org/
   trusted-substituters =
   trusted-public-keys = hydra.iohk.io:f/Ea+s+dFdN+3Y/G+FDgSq+a5NEWhJGzdjvKNGv0/EQ= cache.nixos.org-1:6NCHdD59X431o0gWypbMrAURkbJ16ZPMQFGspcDShjY=
   max-jobs = 2  # run at most two builds at once
   cores = 0     # the builder will use all available CPU cores
   extra-sandbox-paths = /System/Library/Frameworks
   

3. Run nix-shell with correct list of arguments or by using existing package.json scripts to load a shell with all the correct versions of all the required dependencies for development.

Development

Running Daedalus with Cardano Node

Selfnode

1. Run yarn nix:selfnode from daedalus.

2. Run yarn dev from the subsequent nix-shell (use KEEP_LOCAL_CLUSTER_RUNNING environment variable to keep the local cluster running after Daedalus exits: KEEP_LOCAL_CLUSTER_RUNNING=true yarn dev)

3. Once Daedalus has started and has gotten past the loading screen run the following commands from a new terminal window if you wish to import funded wallets:

   • Byron wallets: yarn byron:wallet:importer
   • Shelley wallets: yarn shelley:wallet:importer
   • Mary wallets: yarn mary:wallet:importer (all of which contain native tokens which are visible once selfnode enters Mary era)
   • Yoroi Byron wallets: yarn yoroi:wallet:importer
   • ITN Byron wallets: yarn itn:byron:wallet:importer [Deprecated]
   • ITN Shelley wallets: yarn itn:shelley:wallet:importer [Deprecated]

   These scripts import 3 wallets by default. You can import up to 10 wallets by supplying WALLET_COUNT environment variable (e.g. WALLET_COUNT=10 yarn mary:wallet:importer).

   List of all funded wallet recovery phrases can be found here: https://github.com/input-output-hk/daedalus/blob/develop/utils/api-importer/mnemonics.js

Notes:

• Cardano wallet process ID shown on the "Diagnostics" screen is faked and expected to match the Cardano node process ID.
• Stake pool metadata is fetched directly by default (IOHK SMASH server option is not available).
• Token metadata is fetched from a mock token metadata server which is automatically ran alongside the local cluster (there is no need to run it manually)
• Daedalus will ask you if you wish to keep the local cluster running after it exits - this option is useful if you need to preserve local cluster state between Daedalus restarts.

Parameter	Value
slotLength	0.2 sec
epochLength	50 slots
desiredPoolNumber	3
minimumUtxoValue	1 ADA

Mainnet

1. Run yarn nix:mainnet from daedalus.
2. Run yarn dev from the subsequent nix-shell

Flight

1. Run yarn nix:flight from daedalus.
2. Run yarn dev from the subsequent nix-shell

Testnet

1. Run yarn nix:testnet from daedalus.
2. Run yarn dev from the subsequent nix-shell

Staging

1. Run yarn nix:staging from daedalus.
2. Run yarn dev from the subsequent nix-shell

Shelley QA

1. Run yarn nix:shelley_qa from daedalus.
2. Run yarn dev from the subsequent nix-shell

Alonzo Purple

1. Run yarn nix:alonzo_purple from daedalus.
2. Run yarn dev from the subsequent nix-shell

Native token metadata server

Daedalus, by default, uses the following metadata server for all networks except for the mainnet: https://metadata.cardano-testnet.iohkdev.io/.

It's also possible to use a mock server locally by running the following command in nix-shell prior to starting Daedalus:

$ mock-token-metadata-server --port 65432 ./utils/cardano/native-tokens/registry.json
Mock metadata server running with url http://localhost:65432/

Then proceed to launch Daedalus and make sure to provide the mock token metadata server port:

$ MOCK_TOKEN_METADATA_SERVER_PORT=65432 yarn dev

This enables you to modify the metadata directly by modifying the registry file directly:

$ vi ./utils/cardano/native-tokens/registry.json        # ..or any other editor, if you prefer

Use the following command to check if the mock server is working correctly:

$ curl -i -H "Content-type: application/json" --data '{"subjects":["789ef8ae89617f34c07f7f6a12e4d65146f958c0bc15a97b4ff169f1"],"properties":["name","description","ticker","unit","logo"]}'
http://localhost:65432/metadata/query

... and expect a "200 OK" response.

Updating upstream dependencies (cardano-wallet, cardano-node, and iohk-nix)

Niv is used to manage the version of upstream dependencies. The versions of these dependencies can be seen in nix/sources.json.

Dependencies are updated with the follow nix commands:

• Update cardano-wallet to the latest master: nix-shell -A devops --arg nivOnly true --run "niv update cardano-wallet"
• Update cardano-wallet to a specific revision: nix-shell -A devops --arg nivOnly true --run "niv update cardano-wallet -a rev=91db88f9195de49d4fb4299c68fc3f6de09856ab"
• Update cardano-node to a specific tag: nix-shell -A devops --arg nivOnly true --run "niv update cardano-node -b tags/1.20.0"
• Update iohk-nix to the latest master: nix-shell -A devops --arg nivOnly true --run "niv update iohk-nix -b master"

Notes

nix-shell also provides a script for updating yarn.lock file:

nix-shell -A fixYarnLock

Cardano Wallet Api documentation

Api documentation for edge cardano-wallet version: https://input-output-hk.github.io/cardano-wallet/api/edge/

Externals

If you use any 3rd party libraries which can't or won't be built with webpack, you must list them in your source/main/webpack.config.js and/or source/renderer/webpack.config.js：

externals: [
  // put your node 3rd party libraries which can't be built with webpack here (mysql, mongodb, and so on..)
]

For a common example, to install Bootstrap, yarn install --save bootstrap and link them in the head of app.html

<link rel="stylesheet" href="../node_modules/bootstrap/dist/css/bootstrap.css" />
<link rel="image/svg+xml" href="../node_modules/bootstrap/dist/fonts/glyphicons-halflings-regular.eot" />
...

Make sure to list bootstrap in externals in webpack.config.base.js or the app won't include them in the package:

externals: ['bootstrap']

Testing

You can find more details regarding tests setup within Running Daedalus acceptance tests README file.

Notes: Be aware that only a single Daedalus instance can run per state directory. So you have to exit any development instances before running tests!

Packaging

$ yarn run package

To package apps for all platforms:

$ yarn run package:all

To package apps with options:

$ yarn run package -- --[option]

Options

• --name, -n: Application name (default: Electron)
• --version, -v: Electron version (default: latest version)
• --asar, -a: asar support (default: false)
• --icon, -i: Application icon
• --all: pack for all platforms

Use electron-packager to pack your app with --all options for macOS, Linux and Windows platform. After build, you will find them in release folder. Otherwise, you will only find one for your OS.

Automated builds

CI/dev build scripts

Platform-specific build scripts facilitate building Daedalus the way it is built by the IOHK CI:

Linux/macOS

This script requires Nix, (optionally) configured with the IOHK binary cache.

scripts/build-installer-unix.sh [OPTIONS..]

The result can be found at installers/csl-daedalus/daedalus-*.pkg.

Windows

This batch file requires Node.js and 7zip.

scripts/build-installer-win64.bat

The result will can be found at .\daedalus-*.exe.

Pure Nix installer build

This will use nix to build a Linux installer. Using the IOHK binary cache will speed things up.

nix build -f ./release.nix mainnet.installer

The result can be found at ./result/daedalus-*.bin.
