server_address?: string – This field is deprecated, but left for backward-compatibility. Evernode endpoint.
endpoints?: string[] – List of Evernode endpoints. Any correct URL format can be specified, including IP addresses. This parameter is prevailing over server_address. Check the full list of supported network endpoints.
network_retries_count?: number – Deprecated. You must use network.max_reconnect_timeout that allows to specify maximum network resolving timeout.
max_reconnect_timeout?: number – Maximum time for sequential reconnections. Must be specified in milliseconds. Default is 120000 (2 min).
reconnect_timeout?: number – Deprecated
message_retries_count?: number – The number of automatic message processing retries that SDK performs in case of Message Expired (507) error - but only for those messages which local emulation was successful or failed with replay protection error. Default is 5.
message_processing_timeout?: number – Timeout that is used to process message delivery for the contracts which ABI does not include "expire" header. If the message is not delivered within the specified timeout the appropriate error occurs. Must be specified in milliseconds. Default is 40000 (40 sec).
wait_for_timeout?: number – Maximum timeout that is used for query response. Must be specified in milliseconds. Default is 40000 (40 sec).
out_of_sync_threshold?: number – DEPRECATED: This parameter was deprecated.
sending_endpoint_count?: number – Maximum number of randomly chosen endpoints the library uses to broadcast a message. Default is 1.
latency_detection_interval?: number – Frequency of sync latency detection. Library periodically checks the current endpoint for blockchain data synchronization latency. If the latency (time-lag) is less then NetworkConfig.max_latency then library selects another endpoint. Must be specified in milliseconds. Default is 60000 (1 min).
max_latency?: number – Maximum value for the endpoint's blockchain data synchronization latency (time-lag). Library periodically checks the current endpoint for blockchain data synchronization latency. If the latency (time-lag) is less then NetworkConfig.max_latency then library selects another endpoint. Must be specified in milliseconds. Default is 60000 (1 min).
query_timeout?: number – Default timeout for http requests. Is is used when no timeout specified for the request to limit the answer waiting time. If no answer received during the timeout requests ends with error. Must be specified in milliseconds. Default is 60000 (1 min).
queries_protocol?: NetworkQueriesProtocol – Queries protocol. HTTP or WS. Default is HTTP.
first_remp_status_timeout?: number – UNSTABLE. First REMP status awaiting timeout. If no status received during the timeout than fallback transaction scenario is activated. Must be specified in milliseconds. Default is 1 (1 ms) in order to start fallback scenario together with REMP statuses processing while REMP is not properly tuned yet.
next_remp_status_timeout?: number – UNSTABLE. Subsequent REMP status awaiting timeout. If no status received during the timeout than fallback transaction scenario is activated. Must be specified in milliseconds. Default is 5000 (5 sec).
signature_id?: number – Network signature ID which is used by VM in signature verifying instructions if capability CapSignatureWithId is enabled in blockchain configuration parameters. This parameter should be set to global_id field from any blockchain block if network can not be reachable at the moment of message encoding and the message is aimed to be sent into network with CapSignatureWithId enabled. Otherwise signature ID is detected automatically inside message encoding functions
access_key?: string – Access key to GraphQL API (Project secret)
