# Configuration
## Common configuration
name | description | value
--- | --- | ---
COMMON_HOME_RPC_URL | The HTTPS URL(s) used to communicate to the RPC nodes in the Home network. Several URLs can be specified, delimited by spaces. If the connection to one of these nodes is lost the next URL is used for connection. | URL(s)
COMMON_FOREIGN_RPC_URL | The HTTPS URL(s) used to communicate to the RPC nodes in the Foreign network. Several URLs can be specified, delimited by spaces. If the connection to one of these nodes is lost the next URL is used for connection. | URL(s)
COMMON_HOME_BRIDGE_ADDRESS | The address of the bridge contract address in the Home network. It is used to listen to events from and send validators' transactions to the Home network. | hexidecimal beginning with "0x"
COMMON_FOREIGN_BRIDGE_ADDRESS | The address of the bridge contract address in the Foreign network. It is used to listen to events from and send validators' transactions to the Foreign network. | hexidecimal beginning with "0x"
COMMON_HOME_GAS_PRICE_SUPPLIER_URL | The URL used to get a JSON response from the gas price prediction oracle for the Home network. The gas price provided by the oracle is used to send the validator's transactions to the RPC node. Since it is assumed that the Home network has a predefined gas price (e.g. the gas price in the Core of POA.Network is `1 GWei`), the gas price oracle parameter can be omitted for such networks. Set to `eip1559-gas-estimation` if you want to use EIP1559 RPC-based gas estimation. | URL

COMMON_FOREIGN_GAS_PRICE_SUPPLIER_URL | The URL used to get a JSON response from the gas price prediction oracle for the Foreign network. The provided gas price is used to send the validator's transactions to the RPC node. If the Foreign network is Ethereum Foundation mainnet, the oracle URL can be: https://gasprice.poa.network. Otherwise this parameter can be omitted. Set to `gas-price-oracle` if you want to use npm `gas-price-oracle` package for retrieving gas price from multiple sources. Set to `eip1559-gas-estimation` if you want to use EIP1559 RPC-based gas estimation. | URL
