EVM-based Chains

The source data is in _data/chains. Each chain has its own file with the filename being the CAIP-2 representation as name and .json ans extension.

Example

{
  "name": "Ethereum Mainnet",
  "chain": "ETH",
  "rpc": [
    "https://mainnet.infura.io/v3/${INFURA_API_KEY}",
    "https://api.mycryptoapi.com/eth"
  ],
  "faucets": [],
  "nativeCurrency": {
    "name": "Ether",
    "symbol": "ETH",
    "decimals": 18
  },
  "infoURL": "https://ethereum.org",
  "shortName": "eth",
  "chainId": 1,
  "networkId": 1,
  "icon": "ethereum",
  "explorers": [{
    "name": "etherscan",
    "url": "https://etherscan.io",
    "icon": "etherscan",
    "standard": "EIP3091"
  }]
}

when an icon is used in either the network or a explorer there must be a json in _data/icons with the name used (e.g. in the above example there must be a ethereum.json and a etherscan.json in there) - the icon jsons look like this:


[
    {
      "url": "ipfs://QmdwQDr6vmBtXmK2TmknkEuZNoaDqTasFdZdu3DRw8b2wt",
      "width": 1000,
      "height": 1628,
      "format": "png"
    }
]

where:

  • the URL must be a IPFS url that is publicly resolveable
  • width and height are positive integers
  • format is either "png", "jpg" or "svg"

If the chain is an L2 or a shard of another chain you can link it to the parent chain like this:

{
  ...
  "parent": {
   "type" : "L2",
   "chain": "eip155-1",
   "bridges": [ {"url":"https://bridge.arbitrum.io"} ]
  }
}

where you need to specify type 2 and the reference to an existing parent. The field about bridges is optional.

You can add a status field e.g. to deprecate a chain (a chain should never be deleted as this would open the door to replay attacks) Other options for status are active (default) or incubating

Aggregation

There are also aggregated json files with all chains automatically assembled:

Collision management

If different chains have the same chainID we list the one with the oldest genesis.
