integer |
| ORACLE_HOME_GAS_PRICE_UPDATE_INTERVAL |
An interval in milliseconds used to get the updated gas price value either from the oracle or from the Home Bridge contract. |

local URL |
| ORACLE_HOME_START_BLOCK |
The block number in the Home network used to start watching for events when the bridge instance is run for the first time. Usually this is the same block where the Home Bridge contract is deployed. If a new validator instance is being deployed for an existing set of validators, the block number could be the latest block in the chain. |
integer |
| ORACLE_FOREIGN_START_BLOCK |
The block number in the Foreign network used to start watching for events when the bridge instance runs for the first time. Usually this is the same block where the Foreign Bridge contract was deployed to. If a new validator instance is being deployed for an existing set of validators, the block number could be the latest block in the chain. |
integer |
| ORACLE_LOG_LEVEL |
Set the level of details in the logs. |
trace / debug / info / warn / error / fatal |
| ORACLE_MAX_PROCESSING_TIME |
The workers processes will be killed if this amount of time (in milliseconds) is elapsed before they finish processing. It is recommended to set this value to 4 times the value of the longest polling time (set with the HOME_POLLING_INTERVAL and FOREIGN_POLLING_INTERVAL variables). To disable this, set the time to 0. |
integer |
| ORACLE_VALIDATOR_ADDRESS_PRIVATE_KEY |
The private key of the bridge validator used to sign confirmations before sending transactions to the bridge contracts. The validator account is calculated automatically from the private key. Every bridge instance (set of watchers and senders) must have its own unique private key. The specified private key is used to sign transactions on both sides of the bridge. |
hexidecimal without "0x" |
| ORACLE_VALIDATOR_ADDRESS |
The public address of the bridge validator |
hexidecimal with "0x" |
| ORACLE_TX_REDUNDANCY |
If set to true, instructs oracle to send eth_sendRawTransaction requests through all available RPC urls defined in COMMON_HOME_RPC_URL and COMMON_FOREIGN_RPC_URL variables instead of using first available one |
|
| ORACLE_HOME_TO_FOREIGN_ALLOWANCE_LIST |
Filename with a list of addresses, separated by newlines. If set, determines the privileged set of accounts whose requests will be automatically processed by the CollectedSignatures watcher. |
string |
| ORACLE_HOME_TO_FOREIGN_BLOCK_LIST |
Filename with a list of addresses, separated by newlines. If set, determines the blocked set of accounts whose requests will not be automatically processed by the CollectedSignatures watcher. Has a lower priority than the ORACLE_HOME_TO_FOREIGN_ALLOWANCE_LIST |
string |
| ORACLE_HOME_TO_FOREIGN_CHECK_SENDER |
If set to true, instructs the oracle to do an extra check for transaction origin in the block/allowance list. false by default. |
true / false |
| ORACLE_ALWAYS_RELAY_SIGNATURES |
If set to true, the oracle will always relay signatures even if it was not the last who finilized the signatures collecting process. The default is false. |
true / false |
| ORACLE_RPC_REQUEST_TIMEOUT |
Timeout in milliseconds for a single RPC request. Default value is ORACLE_*_RPC_POLLING_INTERVAL * 2. |
integer |
| ORACLE_HOME_TX_RESEND_INTERVAL |
Interval in milliseconds for automatic resending of stuck transactions for Home sender service. Defaults to 20 minutes. |
integer |
| ORACLE_FOREIGN_TX_RESEND_INTERVAL |
Interval in milliseconds for automatic resending of stuck transactions for Foreign sender service. Defaults to 20 minutes. |
integer |
| ORACLE_SHUTDOWN_SERVICE_URL |
Optional external URL to some other service/monitor/configuration manager that controls the remote shutdown process. GET request should return application/json message with the following schema: { shutdown: true/false }. |
URL |
| ORACLE_SHUTDOWN_SERVICE_POLLING_INTERVAL |
Optional interval in milliseconds used to request the side RPC node or external shutdown service. Default is 120000. |
integer |
| ORACLE_SIDE_RPC_URL |
Optional HTTPS URL(s) for communication with the external shutdown service or side RPC nodes, used for shutdown manager activities. 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) |
| ORACLE_FOREIGN_ARCHIVE_RPC_URL |
Optional HTTPS URL(s) for communication with the archive nodes on the foreign network. Only used in AMB bridge mode for async information request processing. 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) |
| ORACLE_SHUTDOWN_CONTRACT_ADDRESS |
Optional contract address in the side chain accessible through ORACLE_SIDE_RPC_URL, where the method passed in ORACLE_SHUTDOWN_CONTRACT_METHOD is implemented. |
address |
| ORACLE_SHUTDOWN_CONTRACT_METHOD |
Method signature to be used in the side chain to identify the current shutdown status. Method should return boolean. Default value is isShutdown(). |
function signature |
| ORACLE_FOREIGN_RPC_BLOCK_POLLING_LIMIT |
Max length for the block range used in eth_getLogs requests for polling contract events for the Foreign chain. Infinite, if not provided. |
integer |
| ORACLE_HOME_RPC_BLOCK_POLLING_LIMIT |
Max length for the block range used in eth_getLogs requests for polling contract events for the Home chain. Infinite, if not provided. |
integer |
| ORACLE_JSONRPC_ERROR_CODES |
Override default JSON rpc error codes that can trigger RPC fallback to the next URL from the list (or a retry in case of a single RPC URL). Default is -32603,-32002,-32005. Should be a comma-separated list of negative integers. |
string |
| ORACLE_VALIDATOR_KEYSTORE_PATH |
Path to the keystore v3 json file with the encrypted validator key. |
string |
| ORACLE_VALIDATOR_KEYSTORE_PASSWORD |
Password from the provided keystore file, oracle won't startup properly, if the provided password is invalid |
string |
