| NEXT_PUBLIC_APP_INSTANCE | `string`*(optional)* | Name of app instance | `wonderful_kepler` |
| NEXT_PUBLIC_APP_PROTOCOL | `http \| https`*(optional)* | App protocol (`https` used as default value) | `https` |
| type | `string` | Network type (used as first part of the base path) | `"xdai"` |
| subType | `string` | Network subtype (used as second part of the base path) | `"mainnet"` |
| title | `string` | Displayed name of the network | `'Gnosis Chain'` |
| basePath | `string` | Network explorer main page url | `'/xdai/mainnet'` |
| group | `mainnets \| testnets \| other` | Indicates in which tab network appears in the menu | `'mainnets'` |
| isAccountSupported | `boolean`*(optional)* | Set to true if network has account feature | `true` |
| icon | `string`*(optional)* | Network icon; if not provided, will fallback to icon predefined in the project; if the project doesn't have icon for such network then the common placeholder will be shown; *Note* that icon size should be 30px by 30px | `"https://www.fillmurray.com/60/60"` |

| assetsNamePath | `string`*(optional)* | Network name for constructing url of token logos according to template `https://raw.githubusercontent.com/trustwallet/assets/master/blockchains/${assetsNamePath}/assets/${tokenAddress}/logo.png`. It should match network name in TrustWallet assets repo, see the full list [here](https://github.com/trustwallet/assets/tree/master/blockchains). The project already has some pre-defined mapping for popular network, which is match assetsNamePath against provided network type and sub-type. So typically you don't need to provide this variable, if you network is in the list or its type in config is conformed to a name in TrustWallet repo. If it is not the case, pass value here | `"ethereum"` |
| icon | `string`*(optional)* | Network icon; if not provided, will fallback to icon predefined in the project; if the project doesn't have icon for such network then the common placeholder will be shown; *Note* that icon size should be 30px by 30px | `'https://www.fillmurray.com/60/60'` |
*Note* the base path for the network is built up from its `type` and `subType` like so `https://blockscout.com/<type>/<subType>`
