Introduction¶

Networks can be either a DagTokenNetwork() class or a MetagraphTokenNetwork() class. These classes have methods for easing API interactions. Both are temporarily configured using the NetworkInfo class [missing ref]. The main difference between the two classes is the parameters they support.

DAG Token Network¶

A network object is instantiated like this:

from pypergraph import DagTokenNetwork()

network = DagTokenNetwork(network_id="mainnet")

Variable	Value	Description
connected_network	NetworkInfo()	Class used to configure `DagTokenNetwork` and `MetagraphTokenNetwork`. See next page for supported configuration.
_network_change	BehaviorSubject()	RxPy BehaviorSubject that stores the emitted events.
network_id	`"mainnet" (default)`, `"integrationnet"`, `"testnet"`	Specify the connected network by setting this value.
l0_api	`Layer0Api( host=connected_network.l0_host )`	Layer 0 API class containing methods for interacting with the global layer 0 API endpoints.
cl1_api	`Layer1Api( host=connected_network.l1_host )`	Layer 1 API class containing methods for interacting with the currency layer 1 API endpoints.
be_api	`BlockExplorerApi( host=self.connected_network.be_url )`	Block explorer API class containing methods for interacting with the Constellation block explorer API endpoints.

RxPy Event Emitter¶

An event is emitted on DagTokenNetwork().set_network(...) called in DagTokenNetwork().config(...).

Key	Value
module	`"network"`
type	`"network_change"`
event	`DagTokenNetwork().get_network()`

Metagraph Token Network¶

from pypergraph import MetagraphTokenNetwork()

metagraph_network = MetagraphTokenNetwork(...)

Variable	Value	Description
connected_network	NetworkInfo()	Class used to configure `DagTokenNetwork` and `MetagraphTokenNetwork`. See next page for supported configuration.
network_id	`"mainnet" (default)`, `"integrationnet"`, `"testnet"`	Specify the connected network by setting this value.
metagraph_id	`None (default)`	The DAG address used to identify the Metagraph (not necessary when transacting DAG).
l0_api	`None (default)`, `MetagraphLayer0Api( connected_network.l0_host )`	Layer 0 API class containing methods for interacting with Metagraph layer 0 API endpoints.
cl1_api	`None (default)`, `MetagraphCurrencyLayerApi( connected_network.currency_l1_host )`	Layer 1 API class containing methods for interacting with Metagraph currency layer 1 API endpoints.
dl1_api	`None (default)`, `MetagraphDataLayerApi( connected_network.data_l1_host )`	Layer 1 API class containing methods for interacting with Metagraph data layer 1 API endpoints. Used for custom data.
be_api	`None (default)`, `BlockExplorerApi( connected_network.block_explorer_url )`	Block explorer API class containing methods for interacting with Constellation’s block explorer.
