PyCardano Chain Contexts

This library contains the various Chain Contexts to use with the PyCardano library.

Basic Usage

Blockfrost

from pccontext import BlockFrostChainContext
from blockfrost import ApiUrls

chain_context = BlockFrostChainContext(
    project_id="your_project_id",
    base_url=ApiUrls.mainnet.value
)

Cardano-CLI

from pccontext import CardanoCliChainContext, CardanoCliNetwork
from pathlib import Path

chain_context = CardanoCliChainContext(
            binary=Path("cardano-cli"),
            socket=Path("node.socket"),
            config_file=Path("config.json"),
            network=CardanoCliNetwork.MAINNET,
)

Koios

from pccontext import KoiosChainContext

chain_context = KoiosChainContext(api_key="api_key")

Ogmios

chain_context = OgmiosChainContext(host="localhost", port=1337)

Kupo

from pccontext import OgmiosChainContext, KupoChainContextExtension

ogmios_chain_context = OgmiosChainContext(host="localhost", port=1337)
chain_context = KupoChainContextExtension(wrapped_backend=ogmios_chain_context)

Offline Transfer File

from pathlib import Path
