This document describes the TOML format for configuration.

See also: Secrets Config

Example

Log.Level = 'debug'

[[EVM]]
ChainID = '1' # Required

[[EVM.Nodes]]
Name = 'fake' # Required
WSURL = 'wss://foo.bar/ws'
HTTPURL = 'https://foo.bar' # Required

Global

InsecureFastScrypt = false # Default
RootDir = '~/.chainlink' # Default
ShutdownGracePeriod = '5s' # Default

InsecureFastScrypt

⚠️ ADVANCED: Do not change this setting unless you know what you are doing.

InsecureFastScrypt = false # Default

InsecureFastScrypt causes all key stores to encrypt using "fast" scrypt params instead. This is insecure and only useful for local testing. DO NOT ENABLE THIS IN PRODUCTION.

RootDir

RootDir = '~/.chainlink' # Default

RootDir is the Chainlink node's root directory. This is the default directory for logging, database backups, cookies, and other misc Chainlink node files. Chainlink nodes will always ensure this directory has 700 permissions because it might contain sensitive data.

ShutdownGracePeriod

ShutdownGracePeriod = '5s' # Default

ShutdownGracePeriod is the maximum time allowed to shut down gracefully. If exceeded, the node will terminate immediately to avoid being SIGKILLed.

Feature

[Feature]
FeedsManager = true # Default
LogPoller = false # Default
UICSAKeys = false # Default

FeedsManager

FeedsManager = true # Default

FeedsManager enables the feeds manager service.

LogPoller

LogPoller = false # Default

LogPoller enables the log poller, an experimental approach to processing logs, required if also using Evm.UseForwarders or OCR2.

UICSAKeys

UICSAKeys = false # Default

UICSAKeys enables CSA Keys in the UI.

Database

[Database]
DefaultIdleInTxSessionTimeout = '1h' # Default
DefaultLockTimeout = '15s' # Default
DefaultQueryTimeout = '10s' # Default
LogQueries = false # Default
MaxIdleConns = 10 # Default
MaxOpenConns = 20 # Default
MigrateOnStartup = true # Default

DefaultIdleInTxSessionTimeout

DefaultIdleInTxSessionTimeout = '1h' # Default

DefaultIdleInTxSessionTimeout is the maximum time allowed for a transaction to be open and idle before timing out. See Postgres idle_in_transaction_session_timeout for more details.

DefaultLockTimeout

DefaultLockTimeout = '15s' # Default

DefaultLockTimeout is the maximum time allowed to wait for database lock of any kind before timing out. See Postgres lock_timeout for more details.

DefaultQueryTimeout

DefaultQueryTimeout = '10s' # Default

DefaultQueryTimeout is the maximum time allowed for standard queries before timing out.

LogQueries

LogQueries = false # Default

LogQueries tells the Chainlink node to log database queries made using the default logger. SQL statements will be logged at debug level. Not all statements can be logged. The best way to get a true log of all SQL statements is to enable SQL statement logging on Postgres.

MaxIdleConns

MaxIdleConns = 10 # Default

MaxIdleConns configures the maximum number of idle database connections that the Chainlink node will keep open. Think of this as the baseline number of database connections per Chainlink node instance. Increasing this number can help to improve performance under database-heavy workloads.

Postgres has connection limits, so you must use caution when increasing this value. If you are running several instances of a Chainlink node or another application on a single database server, you might run out of Postgres connection slots if you raise this value too high.

MaxOpenConns

MaxOpenConns = 20 # Default

MaxOpenConns configures the maximum number of database connections that a Chainlink node will have open at any one time. Think of this as the maximum burst upper bound limit of database connections per Chainlink node instance. Increasing this number can help to improve performance under database-heavy workloads.

Postgres has connection limits, so you must use caution when increasing this value. If you are running several instances of a Chainlink node or another application on a single database server, you might run out of Postgres connection slots if you raise this value too high.

MigrateOnStartup

MigrateOnStartup = true # Default

MigrateOnStartup controls whether a Chainlink node will attempt to automatically migrate the database on boot. If you want more control over your database migration process, set this variable to false and manually migrate the database using the CLI migrate command instead.

Database.Backup

[Database.Backup]
Mode = 'none' # Default
Dir = 'test/backup/dir' # Example
OnVersionUpgrade = true # Default
Frequency = '1h' # Default

As a best practice, take regular database backups in case of accidental data loss. This best practice is especially important when you upgrade your Chainlink node to a new version. Chainlink nodes support automated database backups to make this process easier.

NOTE: Dumps can cause high load and massive database latencies, which will negatively impact the normal functioning of the Chainlink node. For this reason, it is recommended to set a URL and point it to a read replica if you enable automatic backups.

Mode

Mode = 'none' # Default

Mode sets the type of automatic database backup, which can be one of none, lite, or full. If enabled, the Chainlink node will always dump a backup on every boot before running migrations. Additionally, it will automatically take database backups that overwrite the backup file for the given version at regular intervals if Frequency is set to a non-zero interval.

none - Disables backups. lite - Dumps small tables including configuration and keys that are essential for the node to function, which excludes historical data like job runs, transaction history, etc. full - Dumps the entire database.

It will write to a file like 'Dir'/backup/cl_backup_<VERSION>.dump. There is one backup dump file per version of the Chainlink node. If you upgrade the node, it will keep the backup taken right before the upgrade migration so you can restore to an older version if necessary.

Dir

Dir = 'test/backup/dir' # Example

Dir sets the directory to use for saving the backup file. Use this if you want to save the backup file in a directory other than the default ROOT directory.

OnVersionUpgrade

OnVersionUpgrade = true # Default

OnVersionUpgrade enables automatic backups of the database before running migrations, when you are upgrading to a new version.

Frequency

Frequency = '1h' # Default

Frequency sets the interval for database dumps, if set to a positive duration and Mode is not none.

Set to 0 to disable periodic backups.

Database.Listener

⚠️ ADVANCED: Do not change these settings unless you know what you are doing.

[Database.Listener]
MaxReconnectDuration = '10m' # Default
MinReconnectInterval = '1m' # Default
FallbackPollInterval = '30s' # Default

These settings control the postgres event listener.

MaxReconnectDuration

MaxReconnectDuration = '10m' # Default

MaxReconnectDuration is the maximum duration to wait between reconnect attempts.

MinReconnectInterval

MinReconnectInterval = '1m' # Default

MinReconnectInterval controls the duration to wait before trying to re-establish the database connection after connection loss. After each consecutive failure this interval is doubled, until MaxReconnectInterval is reached. Successfully completing the connection establishment procedure resets the interval back to MinReconnectInterval.

FallbackPollInterval

FallbackPollInterval = '30s' # Default

FallbackPollInterval controls how often clients should manually poll as a fallback in case the postgres event was missed/dropped.

Database.Lock

⚠️ ADVANCED: Do not change these settings unless you know what you are doing.

[Database.Lock]
Enabled = true # Default
LeaseDuration = '10s' # Default
LeaseRefreshInterval = '1s' # Default

Ideally, you should use a container orchestration system like Kubernetes to ensure that only one Chainlink node instance can ever use a specific Postgres database. However, some node operators do not have the technical capacity to do this. Common use cases run multiple Chainlink node instances in failover mode as recommended by our official documentation. The first instance takes a lock on the database and subsequent instances will wait trying to take this lock in case the first instance fails.

• If your nodes or applications hold locks open for several hours or days, Postgres is unable to complete internal cleanup tasks. The Postgres maintainers explicitly discourage holding locks open for long periods of time.

Because of the complications with advisory locks, Chainlink nodes with v2.0 and later only support lease locking mode. The lease locking mode works using the following process:

• Node A creates one row in the database with the client ID and updates it once per second.
• Node B spinlocks and checks periodically to see if the client ID is too old. If the client ID is not updated after a period of time, node B assumes that node A failed and takes over. Node B becomes the owner of the row and updates the client ID once per second.
• If node A comes back, it attempts to take out a lease, realizes that the database has been leased to another process, and exits the entire application immediately.

Enabled

Enabled = true # Default

Enabled enables the database lock.

LeaseDuration

LeaseDuration = '10s' # Default

LeaseDuration is how long the lease lock will last before expiring.

LeaseRefreshInterval

LeaseRefreshInterval = '1s' # Default

LeaseRefreshInterval determines how often to refresh the lease lock. Also controls how often a standby node will check to see if it can grab the lease.

The available levels are:

• "debug": Useful for forensic debugging of issues.
• "info": High-level informational messages. (default)
• "warn": A mild error occurred that might require non-urgent action. Check these warnings semi-regularly to see if any of them require attention. These warnings usually happen due to factors outside of the control of the node operator. Examples: Unexpected responses from a remote API or misleading networking errors.
• "error": An unexpected error occurred during the regular operation of a well-maintained node. Node operators might need to take action to remedy this error. Check these regularly to see if any of them require attention. Examples: Use of deprecated configuration options or incorrectly configured settings that cause a job to fail.
• "crit": A critical error occurred. The node might be unable to function. Node operators should take immediate action to fix these errors. Examples: The node could not boot because a network socket could not be opened or the database became inaccessible.
• "panic": An exceptional error occurred that could not be handled. If the node is unresponsive, node operators should try to restart their nodes and notify the Chainlink team of a potential bug.
• "fatal": The node encountered an unrecoverable problem and had to exit.

JSONConsole

JSONConsole = false # Default

JSONConsole enables JSON logging. Otherwise, the log is saved in a human-friendly console format.

UnixTS

MaxSize

MaxSize = '5120mb' # Default

MaxSize determines the log file's max size in megabytes before file rotation. Having this not set will disable logging to disk. If your disk doesn't have enough disk space, the logging will pause and the application will log errors until space is available again.

Values must have suffixes with a unit like: 5120mb (5,120 megabytes). If no unit suffix is provided, the value defaults to b (bytes). The list of valid unit suffixes are:

• b (bytes)
• kb (kilobytes)
• mb (megabytes)
• gb (gigabytes)

MaxSuccessfulRuns

MaxSuccessfulRuns = 10000 # Default

MaxSuccessfulRuns caps the number of completed successful runs per pipeline spec in the database. You can set it to zero as a performance optimisation; this will avoid saving any successful run.

Note this is not a hard cap, it can drift slightly larger than this but not by more than 5% or so.

ReaperInterval

Enabled

Enabled = false # Default

Enabled enables OCR2 jobs.

ContractConfirmations

ContractConfirmations = 3 # Default

ContractConfirmations is the number of block confirmations to wait for before enacting an on-chain configuration change. This value doesn't need to be very high (in particular, it does not need to protect against malicious re-orgs). Since configuration changes create some overhead, and mini-reorgs are fairly common, recommended values are between two and ten.

Malicious re-orgs are not any more of concern here than they are in blockchain applications in general: Since nodes check the contract for the latest config every ContractConfigTrackerPollInterval.Seconds(), they will come to a common view of the current config within any interval longer than that, as long as the latest setConfig transaction in the longest chain is stable. They will thus be able to continue reporting after the poll interval, unless an adversary is able to repeatedly re-org the transaction out during every poll interval, which would amount to the capability to censor any transaction.

Note that 1 confirmation implies that the transaction/event has been mined in one block. 0 confirmations would imply that the event would be recognised before it has even been mined, which is not currently supported. e.g. Current block height: 42 Changed in block height: 43 Contract config confirmations: 1 STILL PENDING

Current block height: 43 Changed in block height: 43 Contract config confirmations: 1 CONFIRMED

BlockchainTimeout

This section applies only if you are running off-chain reporting jobs.

Enabled

Enabled = false # Default

Enabled enables OCR jobs.

ObservationTimeout

ObservationTimeout = '5s' # Default

ObservationTimeout is the timeout for making observations using the DataSource.Observe method. (This is necessary because an oracle's operations are serialized, so blocking forever on an observation would break the oracle.)

BlockchainTimeout

BlockchainTimeout = '20s' # Default

BlockchainTimeout is the timeout for blockchain queries (mediated through ContractConfigTracker and ContractTransmitter). (This is necessary because an oracle's operations are serialized, so blocking forever on a chain interaction would break the oracle.)

OutgoingMessageBufferSize = 10 # Default
PeerID = '12D3KooWMoejJznyDuEk5aX6GvbjaG12UzeornPCBNzMRqdwrFJw' # Example
TraceLogging = false # Default

P2P supports multiple networking stack versions. You may configure [P2P.V1], [P2P.V2], or both to run simultaneously. If both are configured, then for each link with another peer, V2 networking will be preferred. If V2 does not work, the link will automatically fall back to V1. If V2 starts working again later, it will automatically be preferred again. This is useful for migrating networks without downtime. Note that the two networking stacks must not be configured to bind to the same IP/port.

Note: P2P.V1 is deprecated will be removed in the future.

All nodes in the OCR network should share the same networking stack.

IncomingMessageBufferSize

IncomingMessageBufferSize = 10 # Default

IncomingMessageBufferSize is the per-remote number of incoming messages to buffer. Any additional messages received on top of those already in the queue will be dropped.

OutgoingMessageBufferSize

OutgoingMessageBufferSize = 10 # Default

OutgoingMessageBufferSize is the per-remote number of outgoing messages to buffer. Any additional messages send on top of those already in the queue will displace the oldest. NOTE: OutgoingMessageBufferSize should be comfortably smaller than remote's IncomingMessageBufferSize to give the remote enough space to process them all in case we regained connection and now send a bunch at once

PeerID

PeerID = '12D3KooWMoejJznyDuEk5aX6GvbjaG12UzeornPCBNzMRqdwrFJw' # Example

AnnouncePort

AnnouncePort = 1337 # Example

AnnouncePort should be set as the externally reachable port of the Chainlink node.

BootstrapCheckInterval

BootstrapCheckInterval = '20s' # Default

BootstrapCheckInterval is the interval at which nodes check connections to bootstrap nodes and reconnect if any of them is lost. Setting this to a small value would allow newly joined bootstrap nodes to get more connectivity more quickly, which helps to make bootstrap process faster. The cost of this operation is relatively cheap. We set this to 1 minute during our test.

DefaultBootstrapPeers

DefaultBootstrapPeers = ['/dns4/example.com/tcp/1337/p2p/12D3KooWMHMRLQkgPbFSYHwD3NBuwtS1AmxhvKVUrcfyaGDASR4U', '/ip4/1.2.3.4/tcp/9999/p2p/12D3KooWLZ9uTC3MrvKfDpGju6RAQubiMDL7CuJcAgDRTYP7fh7R'] # Example

DefaultBootstrapPeers is the default set of bootstrap peers.

DHTAnnouncementCounterUserPrefix

DHTAnnouncementCounterUserPrefix = 0 # Default

DHTAnnouncementCounterUserPrefix can be used to restore the node's ability to announce its IP/port on the P2P network after a database rollback. Make sure to only increase this value, and never decrease it. Don't use this variable unless you really know what you're doing, since you could semi-permanently exclude your node from the P2P network by misconfiguring it.

DHTLookupInterval

⚠️ ADVANCED: Do not change this setting unless you know what you are doing.

DHTLookupInterval = 10 # Default

DHTLookupInterval is the interval between which we do the expensive peer lookup using DHT.

Every DHTLookupInterval failures to open a stream to a peer, we will attempt to lookup its IP from DHT

ListenIP

ListenIP = '0.0.0.0' # Default

ListenIP is the default IP address to bind to.

ListenPort

ListenPort = 1337 # Example

ListenPort is the port to listen on. If left blank, the node randomly selects a different port each time it boots. It is highly recommended to set this to a static value to avoid network instability.

NewStreamTimeout

⚠️ ADVANCED: Do not change this setting unless you know what you are doing.

NewStreamTimeout = '10s' # Default

NewStreamTimeout is the maximum length of time to wait to open a stream before we give up. We shouldn't hit this in practice since libp2p will give up fast if it can't get a connection, but it is here anyway as a failsafe. Set to 0 to disable any timeout on top of what libp2p gives us by default.

PeerstoreWriteInterval

⚠️ ADVANCED: Do not change this setting unless you know what you are doing.

PeerstoreWriteInterval = '5m' # Default

PeerstoreWriteInterval controls how often the peerstore for the OCR V1 networking stack is persisted to the database.

AnnounceAddresses

AnnounceAddresses = ['1.2.3.4:9999', '[a52d:0:a88:1274::abcd]:1337'] # Example

AnnounceAddresses is the addresses the peer will advertise on the network in host:port form as accepted by the TCP version of Go’s net.Dial. The addresses should be reachable by other nodes on the network. When attempting to connect to another node, a node will attempt to dial all of the other node’s AnnounceAddresses in round-robin fashion.

DefaultBootstrappers

DefaultBootstrappers = ['12D3KooWMHMRLQkgPbFSYHwD3NBuwtS1AmxhvKVUrcfyaGDASR4U@1.2.3.4:9999', '12D3KooWM55u5Swtpw9r8aFLQHEtw7HR4t44GdNs654ej5gRs2Dh@example.com:1234'] # Example

DefaultBootstrappers is the default bootstrapper peers for libocr's v2 networking stack.

Oracle nodes typically only know each other’s PeerIDs, but not their hostnames, IP addresses, or ports. DefaultBootstrappers are special nodes that help other nodes discover each other’s AnnounceAddresses so they can communicate. Nodes continuously attempt to connect to bootstrappers configured in here. When a node wants to connect to another node (which it knows only by PeerID, but not by address), it discovers the other node’s AnnounceAddresses from communications received from its DefaultBootstrappers or other discovered nodes. To facilitate discovery, nodes will regularly broadcast signed announcements containing their PeerID and AnnounceAddresses.

DeltaDial

DeltaDial = '15s' # Default

DeltaDial controls how far apart Dial attempts are

DeltaReconcile

DeltaReconcile = '1m' # Default

DeltaReconcile controls how often a Reconcile message is sent to every peer.

ListenAddresses

ListenAddresses = ['1.2.3.4:9999', '[a52d:0:a88:1274::abcd]:1337'] # Example

ListenAddresses is the addresses the peer will listen to on the network in host:port form as accepted by net.Listen(), but the host and port must be fully specified and cannot be empty. You can specify 0.0.0.0 (IPv4) or :: (IPv6) to listen on all interfaces, but that is not recommended.
