Installation

From PyPI

pip install mesc

From Source

git clone https://github.com/paradigmxyz/mesc
cd mesc
pip install ./

Example Usage

from typing import Any, Mapping, Sequence
import mesc

# check whether mesc is enabled
enabled: bool = mesc.is_mesc_enabled()

# get the default endpoint
endpoint: Endpoint | None = mesc.get_default_endpoint()

# get the default endpoint of a network
endpoint: Endpoint | None = mesc.get_endpoint_by_network(5)

# get the default endpoint for a particular tool
endpoint: Endpoint | None = mesc.get_default_endpoint(profile='xyz_tool')

# get the default endpoint of a network for a particular tool
endpoint: Endpoint | None = mesc.get_endpoint_by_network(5, profile='xyz_tool')

# get an endpoint by name
endpoint: Endpoint | None = mesc.get_endpoint_by_name('local_goerli')

# parse a user-provided string into a matching endpoint
# (first try 1. endpoint name, then 2. chain id, then 3. network name)
endpoint: Endpoint | None = mesc.get_endpoint_by_query(user_str, profile='xyz_tool')

# find all endpoints matching given criteria
endpoints: Sequence[Endpoint] = mesc.find_endpoints(chain_id=5)

# get non-endpoint metadata
metadata: Mapping[str, Any] = mesc.get_global_metadata(profile='xyz_tool')
