const ethereum: Chain = chains.getById(ChainId.EthereumMainnet)
ethereum.chain // 'ETH'

TODO:

• Add webhook that watches the chains repo and triggers an update to this package whenever that repo gets updated
  • Add check in the deploy script to make sure that the types are correct before publishing
• Add Tests
  • Once quicktype is added, test with different chains.json objects to make sure it can handle new types
• Use quicktype to autogen types from json
• Autogen Chain Id enum
• Autogen Chain Name enum
