# EVM Chain support (Networks) - Internal Processes

### 1. Prep contracts and subgraphs
New chains just need to support the molochv21 and minions so these factory contracts should be deployed.

https://github.com/HausDAO/Molochv2.1
https://github.com/HausDAO/MinionSummoner

Subgraphs will need to be created and usually hosted somewhere. We update often so a pipeline for deploying updates should be indentified.

https://github.com/HausDAO/daohaus-supergraph
https://github.com/HausDAO/daohaus-stats

boost graph
- wrapnzap/transmutation

### 2. PR into `develop` branch with updated chains.js
https://github.com/HausDAO/pokemol-web/blob/app/src/utils/chain.js

Add details for the chain- example:

  '0x4a': {
    name: 'IDChain',
    short_name: 'idchain',
    chain: 'IDChain',
    network: 'idchain',
    network_id: 74,
    chain_id: '0x4a',
    providers: ['walletconnect'],
    rpc_url: 'https://idchain.one/rpc/',
    metadata_api_url: 'https://data.daohaus.club',
    abi_api_url:
      'https://explorer.idchain.one/api?module=contract&action=getabi&address=',
    subgraph_url:
      'https://graph.idchain.one/subgraphs/name/idchain/daohaus-supergraph/graphql',
    stats_graph_url:
      'https://graph.idchain.one/subgraphs/name/idchain/daohaus-stats/graphql',
    boosts_graph_url: '',
    minion_factory_addr: '0x90253955D4066eE27C183B4644089a5A04A888F1',
    moloch_factory_addr: '0x99B4525D6d6F6c3161D0abd6A58B482f46ad5Cd0',
    dai_contract: '0xE1A400f340bf4eeDbc4Bbb553f1BFf7Ec4656E3e',
    weth_contract: '0x2b309226500ADc5956a422950A2AD6E6333Bb315',
  },

The 'weth' contract address should be for the erc20 wrapped version of the native gas token for the chain.
