class ChainId[source]#

Bases: Enum

Ethereum EVM chain ids and chain metadata.

Chain id is an integer that defines the identity of a blockchain, all running on same or different EVM implementations.

This class also provides various other metadata attributes besides ChainId.value, like ChainId.get_slug(). Some of this data is handcoded, some is pulled from chains submodule.

For the full chain id list see:
