Cardano Wallet

Cardano Wallet is software that helps you manage your Ada. You can use it to send and receive payments on the Cardano blockchain.

This project provides an HTTP Application Programming Interface (API) and command-line interface (CLI) for working with your wallet.

It can be used as a component of a frontend such as Daedalus, which provides a friendly user interface for wallets. Most users who would like to use Cardano should start with Daedalus.

The cardano-wallet executable is an HTTP server that manages your wallet(s).

In order to retrieve blockchain data and send transactions, the cardano-wallet executable must connect to a running cardano-node process. This QuickStart guide presents you several ways of doing that, which you can later customize to your needs.

You can use Docker to download, configure and start the cardano-wallet and cardano-node executables.

First you have to choose a Cardano network to connect to. The network mainnet keeps track of the real money. The networks private, sanchonet, and preprod are test networks.

cd into the directory ./run/$NETWORK/docker corresponding to your choice of NETWORK.

Then

• start a node and wallet with ./run.sh start
• stop the node and wallet with ./run.sh stop
• inspect the logs with ./run.sh logs
• start a node and wallet, wait until they are fully synchronized to the network, and stop again with ./run.sh sync

Accepeted variables for the start command are:

• WALLET_PORT (default 8090): the port the wallet will listen to on your host, in case of absence a random port will be used
• WALLET_DB (default ./databases/wallet-db): the directory where the wallet database will be stored
• NODE_DB (default ./databases/node-db): the directory where the node database will be stored
• NODE_SOCKET_DIR (default ./.): the directory where the node socket will be created
• NODE_CONFIGS: the directory where the node configuration files will be retrieved from. In the absence of this variable, the node will use the configurations in the image. You have to reflect the directory structure of the node configuration files in the image to use the docker-compose.yml file.
• WALLET_TAG (default 2024.7.7): the tag of the wallet image to use, can be release-candidate

For example, to start a wallet on private network:

cd run/private/docker
WALLET_PORT=8090 ./run.sh start
curl http:https://localhost:8090/v2/network/information | jq

Then you can inspect the logs with

./run.sh logs

And stop the services with

./run.sh stop

See also Docker for more information about using docker.

You can set your variables populating the .env file in your working directory.

WALLET_PORT=8090
WALLET_DB=./my-databases/wallet-db
NODE_DB=./my-databases/node-db
NODE_SOCKET_DIR=/tmp/cardano-node-socket
NODE_CONFIGS=./my-configs-i-just-copied-from-a-malicious-site
WALLET_TAG=2024.7.27

You can use Nix to download the cardano-wallet and cardano-node executables.

cd into the directory ./run/$NETWORK/nix corresponding to your choice of NETWORK.

The nix script serve only as a template, you can modify it to suit your needs. It actually support one only command sync that starts a wallet and a node and use the wallet api to wait for the node to sync, then it stops the wallet and the node.

For example, to sync a node on private using nix:

cd run/private/nix
./run.sh sync

WALLET_TAG is not supported in the nix script. You will run the code that you just cloned.

NixOS users can also use the NixOS service.

On mainnet, the Minimum System Requirements for a cardano-node are high:

• 200GB of disk space (for the history of blocks)
• 24GB of RAM (for the current UTxO set)

To speed up the synchronization process, you can download a snapshot of the cardano-node state database, but you will have much less security than the full Ouroboros consensus protocol. In particular, the snapshot could be created by a malicious block producer and contain erroneous transactions that are not consensus on mainnet!

cd run/mainnet/docker
./snapshot.sh

The snapshot.sh will try to use NODE_DB as the directory to store the snapshot.

Wether you used a snapshot or not, you can now start the wallet with

cd run/mainnet/docker
./run.sh start

Notice that the wallet port is not exposed. For security reasons you should not expose the wallet port to the internet. The cardano-wallet is not designed to be exposed to the internet. It would be no different from exposing the keys to your bank account to the internet!

You can connect to the wallet by attaching a container to the network and using the internal port.

docker run -it --network mainnet_default alpine/curl curl http:https://cardano-wallet:8090/v2/network/information | jq

Or modify the docker-compose.yml to host your client in the mainnet_default network.

Preprod network is broken for node 9.1.0 at some block in the past. One way to overcome that limitation is to download a snapshot that used an old version node (1.35.2) to trespass that point. Use snpashot.sh to download the snapshot.

cd run/preprod/docker
./snapshot.sh
./run.sh sync

We provide executables as part of our releases. Please also see the installation instructions highlighted in the release notes.

The cardano-wallet repository was introduced during the Shelley phase of the Cardano blockchain. Previously, during the Byron phase, the wallet was part of the cardano-sl repository. (This is useful to know — sometimes the ghosts of the past come back to haunt us in the form of obscure bugs.)
