Library to interact with cardano network

pydano

Python helper scripts to do minting and transactions via cardano_cli.

Sending ADA from one wallet to other wallets

python scripts/pydano_cli.py --input_address addr_test1vqe6pyeqq66nffkku7ra8xhss97nzltclgnhn20u7xyhzwcu5zzvt --pay execute_transaction.json --signing_key keys/payment2.skey

Transactions to be executed written in a JSON file with the following format:

[
    {
	"address": "addr_test1vqe6pyeqq66nffkku7ra8xhss97nzltclgnhn20u7xyhzwcu5zzvt",
	"quantity": 1379280,
	"token_name": "lovelace"
    },
    {
	"address": "addr_test1vqe6pyeqq66nffkku7ra8xhss97nzltclgnhn20u7xyhzwcu5zzvt",
	"quantity": 1,
	"token_name": "29270c0384408dcf4fae241d756ec7632f9bb9a2abb2627d371bc262.cheekyunttest10"
    }
]

We use the input address as the change_address for ADA and non-ADA assets.

Minting Tokens

Command:

python scripts/pydano_cli.py --input_address addr_test1vqe6pyeqq66nffkku7ra8xhss97nzltclgnhn20u7xyhzwcu5zzvt --mint mint_transaction.json --signing_key keys/payment2.skey --minting_script data/policy.script --log_level DEBUG --min_utxo 1758582

Pass the assets to be minted using the --mint option. An example of a file is:

[
    {
	"address": "addr_test1vqe6pyeqq66nffkku7ra8xhss97nzltclgnhn20u7xyhzwcu5zzvt",
	"token_name": "cheekyunttest41"
    },
    {
	"address": "addr_test1vqe6pyeqq66nffkku7ra8xhss97nzltclgnhn20u7xyhzwcu5zzvt",
	"token_name": "cheekyunttest40"
    }

Connecting to remote cardano node instead of starting node on your laptop.

1. Grab the latest cardano binary from Download Link
2. Extract cardano-cli locally by extracting the downloaded package. tar xzfv cardano-node-1.29.0-linux.tar.gz
3. Install cardano-* binaries on local path. cp cardano-* $HOME/.local/bin/
4. [Optional] Start socat on your server, where actual node is running. nohup socat TCP-LISTEN:8080,fork,reuseaddr, UNIX-CONNECT:$CARDANO_NODE_SOCKET_PATH&
5. Start socat on your local machine, to connect to socket on remote node. socat UNIX-LISTEN:node.socket,fork,reuseaddr,unlink-early, TCP:<IP_ADDR>:8080 [Replace <IP_ADDR> with ip of your remote machine]
6. Export the path of pwd/node.socket as CARDANO_NODE_SOCKET_PATH

We are using 8080 port for communication between our remote node and local node here. Make sure:

1. 8080 port is open on remote host.
2. echo $CARDANO_NODE_SOCKET_PATH points to the correct location of socket

P.S: refer to the ./scripts/run_socat.sh to starting socat locally.

P.S: This is untested code, and loss incurred due to the use of this library is not our responsibility!!!
