Node Config (TOML)

This document describes the TOML format for configuration.

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.

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

UnixTS = false # Default

UnixTS enables legacy unix timestamps.

Previous versions of Chainlink nodes wrote JSON logs with a unix timestamp. As of v1.1.0 and up, the default has changed to use ISO8601 timestamps for better readability.

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)
tb (terabytes)

MaxAgeDays determines the log file's max age in days before file rotation. Keeping this config with the default value will not remove log files based on age.

MaxBackups

MaxBackups = 1 # Default

MaxBackups determines the maximum number of old log files to retain. Keeping this config with the default value retains all old log files. The MaxAgeDays variable can still cause them to get deleted.

TraceLogging = false # Default

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

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.

ChainID

ChainID = '1' # Example

ChainID is the EVM chain ID. Mandatory.

Enabled

Enabled = true # Default

Enabled enables this chain.

AutoCreateKey

AutoCreateKey = true # Default

AutoCreateKey, if set to true, will ensure that there is always at least one transmit key for the given chain.

BlockBackfillDepth

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

BlockBackfillDepth = 10 # Default

BlockBackfillDepth specifies the number of blocks before the current HEAD that the log broadcaster will try to re-consume logs from.

BlockBackfillSkip

BlockBackfillSkip = false # Default

BlockBackfillSkip enables skipping of very long backfills.

ChainType

ChainType = 'arbitrum' # Example

ChainType is automatically detected from chain ID. Set this to force a certain chain type regardless of chain ID. Available types: arbitrum, metis, optimismBedrock, xdai, celo, kroma, wemix, zksync, scroll

FinalityDepth

FinalityDepth = 50 # Default

FinalityDepth is the number of blocks after which an ethereum transaction is considered "final". Note that the default is automatically set based on chain ID so it should not be necessary to change this under normal operation. BlocksConsideredFinal determines how deeply we look back to ensure that transactions are confirmed onto the longest chain There is not a large performance penalty to setting this relatively high (on the order of hundreds) It is practically limited by the number of heads we store in the database and should be less than this with a comfortable margin. If a transaction is mined in a block more than this many blocks ago, and is reorged out, we will NOT retransmit this transaction and undefined behaviour can occur including gaps in the nonce sequence that require manual intervention to fix. Therefore this number represents a number of blocks we consider large enough that no re-org this deep will ever feasibly happen.

Special cases: FinalityDepth=0 would imply that transactions can be final even before they were mined into a block. This is not supported. FinalityDepth=1 implies that transactions are final after we see them in one block.

Examples:

Transaction sending: A transaction is sent at block height 42

FinalityDepth is set to 5 A re-org occurs at height 44 starting at block 41, transaction is marked for rebroadcast A re-org occurs at height 46 starting at block 41, transaction is marked for rebroadcast A re-org occurs at height 47 starting at block 41, transaction is NOT marked for rebroadcast

FinalityTagEnabled

FinalityTagEnabled = false # Default

FinalityTagEnabled means that the chain supports the finalized block tag when querying for a block. If FinalityTagEnabled is set to true for a chain, then FinalityDepth field is ignored. Finality for a block is solely defined by the finality related tags provided by the chain's RPC API. This is a placeholder and hasn't been implemented yet.

FlagsContractAddress

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

FlagsContractAddress = '0xae4E781a6218A8031764928E88d457937A954fC3' # Example

FlagsContractAddress can optionally point to a Flags contract. If set, the node will lookup that contract for each job that supports flags contracts (currently OCR and FM jobs are supported). If the job's contractAddress is set as hibernating in the FlagsContractAddress address, it overrides the standard update parameters (such as heartbeat/threshold).

LinkContractAddress

LinkContractAddress = '0x538aAaB4ea120b2bC2fe5D296852D948F07D849e' # Example

LinkContractAddress is the canonical ERC-677 LINK token contract address on the given chain. Note that this is usually autodetected from chain ID.

LogBackfillBatchSize

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

LogBackfillBatchSize = 1000 # Default

LogBackfillBatchSize sets the batch size for calling FilterLogs when we backfill missing logs.

LogPollInterval

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

LogPollInterval = '15s' # Default

LogPollInterval works in conjunction with Feature.LogPoller. Controls how frequently the log poller polls for logs. Defaults to the block production rate.

LogKeepBlocksDepth

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

LogKeepBlocksDepth = 100000 # Default

LogKeepBlocksDepth works in conjunction with Feature.LogPoller. Controls how many blocks the poller will keep, must be greater than FinalityDepth+1.

MinContractPayment

MinContractPayment = '10000000000000 juels' # Default

MinContractPayment is the minimum payment in LINK required to execute a direct request job. This can be overridden on a per-job basis.

MinIncomingConfirmations

MinIncomingConfirmations = 3 # Default

MinIncomingConfirmations is the minimum required confirmations before a log event will be consumed.

NonceAutoSync

NonceAutoSync = true # Default

NonceAutoSync enables automatic nonce syncing on startup. Chainlink nodes will automatically try to sync its local nonce with the remote chain on startup and fast forward if necessary. This is almost always safe but can be disabled in exceptional cases by setting this value to false.

NoNewHeadsThreshold

NoNewHeadsThreshold = '3m' # Default

NoNewHeadsThreshold controls how long to wait after receiving no new heads before NodePool marks rpc endpoints as out-of-sync, and HeadTracker logs warnings.

Set to zero to disable out-of-sync checking.

OperatorFactoryAddress

OperatorFactoryAddress = '0xa5B85635Be42F21f94F28034B7DA440EeFF0F418' # Example

OperatorFactoryAddress is the address of the canonical operator forwarder contract on the given chain. Note that this is usually autodetected from chain ID.

RPCDefaultBatchSize

RPCDefaultBatchSize = 250 # Default

RPCDefaultBatchSize is the default batch size for batched RPC calls.

RPCBlockQueryDelay

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

RPCBlockQueryDelay = 1 # Default

RPCBlockQueryDelay controls the number of blocks to trail behind head in the block history estimator and balance monitor. For example, if this is set to 3, and we receive block 10, block history estimator will fetch block 7.

CAUTION: You might be tempted to set this to 0 to use the latest possible block, but it is possible to receive a head BEFORE that block is actually available from the connected node via RPC, due to race conditions in the code of the remote ETH node. In this case you will get false "zero" blocks that are missing transactions.

EVM.Transactions

ForwardersEnabled

ForwardersEnabled = false # Default

ForwardersEnabled enables or disables sending transactions through forwarder contracts.

MaxInFlight

MaxInFlight = 16 # Default

MaxInFlight controls how many transactions are allowed to be "in-flight" i.e. broadcast but unconfirmed at any one time. You can consider this a form of transaction throttling.

The default is set conservatively at 16 because this is a pessimistic minimum that both geth and parity will hold without evicting local transactions. If your node is falling behind and you need higher throughput, you can increase this setting, but you MUST make sure that your ETH node is configured properly otherwise you can get nonce gapped and your node will get stuck.

0 value disables the limit. Use with caution.

MaxQueued

MaxQueued = 250 # Default

MaxQueued is the maximum number of unbroadcast transactions per key that are allowed to be enqueued before jobs will start failing and rejecting send of any further transactions. This represents a sanity limit and generally indicates a problem with your ETH node (transactions are not getting mined).

Do NOT blindly increase this value thinking it will fix things if you start hitting this limit because transactions are not getting mined, you will instead only make things worse.

In deployments with very high burst rates, or on chains with large re-orgs, you may consider increasing this.

0 value disables any limit on queue size. Use with caution.

ReaperInterval

ReaperInterval = '1h' # Default

ReaperInterval controls how often the EthTx reaper will run.

ReaperThreshold

ReaperThreshold = '168h' # Default

ReaperThreshold indicates how old an EthTx ought to be before it can be reaped.

ResendAfterThreshold

ResendAfterThreshold = '1m' # Default

ResendAfterThreshold controls how long to wait before re-broadcasting a transaction that has not yet been confirmed.

Mode

Mode = 'BlockHistory' # Default

Mode controls what type of gas estimator is used.

FixedPrice uses static configured values for gas price (can be set via API call).
BlockHistory dynamically adjusts default gas price based on heuristics from mined blocks.
L2Suggested mode is deprecated and replaced with SuggestedPrice.
SuggestedPrice is a mode which uses the gas price suggested by the rpc endpoint via eth_gasPrice.
Arbitrum is a special mode only for use with Arbitrum blockchains. It uses the suggested gas price (up to ETH_MAX_GAS_PRICE_WEI, with 1000 gwei default) as well as an estimated gas limit (up to ETH_GAS_LIMIT_MAX, with 1,000,000,000 default).

Chainlink nodes decide what gas price to use using an Estimator. It ships with several simple and battle-hardened built-in estimators that should work well for almost all use-cases. Note that estimators will change their behaviour slightly depending on if you are in EIP-1559 mode or not.

You can also use your own estimator for gas price by selecting the FixedPrice estimator and using the exposed API to set the price.

An important point to note is that the Chainlink node does not ship with built-in support for go-ethereum's estimateGas call. This is for several reasons, including security and reliability. We have found empirically that it is not generally safe to rely on the remote ETH node's idea of what gas price should be.

PriceDefault

PriceDefault = '20 gwei' # Default

PriceDefault is the default gas price to use when submitting transactions to the blockchain. Will be overridden by the built-in BlockHistoryEstimator if enabled, and might be increased if gas bumping is enabled.

(Only applies to legacy transactions)

Can be used with the chainlink setgasprice to be updated while the node is still running.

PriceMax

PriceMax = '115792089237316195423570985008687907853269984665.640564039457584007913129639935 tether' # Default

PriceMax is the maximum gas price. Chainlink nodes will never pay more than this for a transaction. This applies to both legacy and EIP1559 transactions. Note that it is impossible to disable the maximum limit. Setting this value to zero will prevent paying anything for any transaction (which can be useful in some rare cases). Most chains by default have the maximum set to 2**256-1 Wei which is the maximum allowed gas price on EVM-compatible chains, and is so large it may as well be unlimited.

PriceMin

PriceMin = '1 gwei' # Default

PriceMin is the minimum gas price. Chainlink nodes will never pay less than this for a transaction.

(Only applies to legacy transactions)

It is possible to force the Chainlink node to use a fixed gas price by setting a combination of these, e.g.

EIP1559DynamicFees = false
PriceMax = 100
PriceMin = 100
PriceDefault = 100
BumpThreshold = 0
Mode = 'FixedPrice'

LimitDefault

LimitDefault = 500_000 # Default

LimitDefault sets default gas limit for outgoing transactions. This should not need to be changed in most cases. Some job types, such as Keeper jobs, might set their own gas limit unrelated to this value.

LimitMax

LimitMax = 500_000 # Default

LimitMax sets a maximum for estimated gas limits. This currently only applies to Arbitrum GasEstimatorMode.

LimitMultiplier

LimitMultiplier = '1.0' # Default

LimitMultiplier is the factor by which a transaction's GasLimit is multiplied before transmission. So if the value is 1.1, and the GasLimit for a transaction is 10, 10% will be added before transmission.

This factor is always applied, so includes L2 transactions which uses a default gas limit of 1 and is also applied to LimitDefault.

LimitTransfer

LimitTransfer = 21_000 # Default

LimitTransfer is the gas limit used for an ordinary ETH transfer.

BumpMin

BumpMin = '5 gwei' # Default

BumpMin is the minimum fixed amount of wei by which gas is bumped on each transaction attempt.

BumpPercent

BumpPercent = 20 # Default

BumpPercent is the percentage by which to bump gas on a transaction that has exceeded BumpThreshold. The larger of GasBumpPercent and GasBumpWei is taken for gas bumps.

BumpThreshold

BumpThreshold = 3 # Default

BumpThreshold is the number of blocks to wait for a transaction stuck in the mempool before automatically bumping the gas price. Set to 0 to disable gas bumping completely.

BumpTxDepth

BumpTxDepth = 16 # Example

BumpTxDepth is the number of transactions to gas bump starting from oldest. Set to 0 for no limit (i.e. bump all). Can not be greater than EVM.Transactions.MaxInFlight. If not set, defaults to EVM.Transactions.MaxInFlight.

EIP1559DynamicFees

EIP1559DynamicFees = false # Default

EIP1559DynamicFees torces EIP-1559 transaction mode. Enabling EIP-1559 mode can help reduce gas costs on chains that support it. This is supported only on official Ethereum mainnet and testnets. It is not recommended to enable this setting on Polygon because the EIP-1559 fee market appears to be broken on all Polygon chains and EIP-1559 transactions are less likely to be included than legacy transactions.

Technical details

Chainlink nodes include experimental support for submitting transactions using type 0x2 (EIP-1559) envelope.

EIP-1559 mode is enabled by default on the Ethereum Mainnet, but can be enabled on a per-chain basis or globally.

This might help to save gas on spikes. Chainlink nodes should react faster on the upleg and avoid overpaying on the downleg. It might also be possible to set EVM.GasEstimator.BlockHistory.BatchSize to a smaller value such as 12 or even 6 because tip cap should be a more consistent indicator of inclusion time than total gas price. This would make Chainlink nodes more responsive and should reduce response time variance. Some experimentation is required to find optimum settings.

Set with caution, if you set this on a chain that does not actually support EIP-1559 your node will be broken.

In EIP-1559 mode, the total price for the transaction is the minimum of base fee + tip cap and fee cap. More information can be found on the official EIP.

Chainlink's implementation of EIP-1559 works as follows:

If you are using FixedPriceEstimator:

With gas bumping disabled, it will submit all transactions with feecap=PriceMax and tipcap=GasTipCapDefault
With gas bumping enabled, it will submit all transactions initially with feecap=GasFeeCapDefault and tipcap=GasTipCapDefault.

If you are using BlockHistoryEstimator (default for most chains):

With gas bumping disabled, it will submit all transactions with feecap=PriceMax and tipcap=<calculated using past blocks>
With gas bumping enabled (default for most chains) it will submit all transactions initially with feecap = ( current block base fee * (1.125 ^ N) + tipcap ) where N is configurable by setting EVM.GasEstimator.BlockHistory.EIP1559FeeCapBufferBlocks but defaults to gas bump threshold+1 and tipcap=<calculated using past blocks>

Bumping works as follows:

Increase tipcap by max(tipcap * (1 + GasBumpPercent), tipcap + GasBumpWei)
Increase feecap by max(feecap * (1 + GasBumpPercent), feecap + GasBumpWei)

A quick note on terminology - Chainlink nodes use the same terms used internally by go-ethereum source code to describe various prices. This is not the same as the externally used terms. For reference:

Base Fee Per Gas = BaseFeePerGas
Max Fee Per Gas = FeeCap
Max Priority Fee Per Gas = TipCap

In EIP-1559 mode, the following changes occur to how configuration works:

All new transactions will be sent as type 0x2 transactions specifying a TipCap and FeeCap. Be aware that existing pending legacy transactions will continue to be gas bumped in legacy mode.
BlockHistoryEstimator will apply its calculations (gas percentile etc) to the TipCap and this value will be used for new transactions (GasPrice will be ignored)
FixedPriceEstimator will use GasTipCapDefault instead of GasPriceDefault for the tip cap
FixedPriceEstimator will use GasFeeCapDefault instaed of GasPriceDefault for the fee cap
PriceMin is ignored for new transactions and GasTipCapMinimum is used instead (default 0)
PriceMax still represents that absolute upper limit that Chainlink will ever spend (total) on a single tx
Keeper.GasTipCapBufferPercent is ignored in EIP-1559 mode and Keeper.GasTipCapBufferPercent is used instead

FeeCapDefault

FeeCapDefault = '100 gwei' # Default

FeeCapDefault controls the fixed initial fee cap, if EIP1559 mode is enabled and FixedPrice gas estimator is used.

TipCapDefault

TipCapDefault = '1 wei' # Default

TipCapDefault is the default gas tip to use when submitting transactions to the blockchain. Will be overridden by the built-in BlockHistoryEstimator if enabled, and might be increased if gas bumping is enabled.

(Only applies to EIP-1559 transactions)

TipCapMin

TipCapMin = '1 wei' # Default

TipCapMinimum is the minimum gas tip to use when submitting transactions to the blockchain.

Only applies to EIP-1559 transactions)

BlockHistorySize = 8 # Default
CheckInclusionBlocks = 12 # Default
CheckInclusionPercentile = 90 # Default
EIP1559FeeCapBufferBlocks = 13 # Example
TransactionPercentile = 60 # Default

These settings allow you to configure how your node calculates gas prices when using the block history estimator. In most cases, leaving these values at their defaults should give good results.

BatchSize

BatchSize = 25 # Default

BatchSize sets the maximum number of blocks to fetch in one batch in the block history estimator. If the BatchSize variable is set to 0, it defaults to EVM.RPCDefaultBatchSize.

BlockHistorySize

BlockHistorySize = 8 # Default

BlockHistorySize controls the number of past blocks to keep in memory to use as a basis for calculating a percentile gas price.

CheckInclusionBlocks

CheckInclusionBlocks = 12 # Default

CheckInclusionBlocks is the number of recent blocks to use to detect if there is a transaction propagation/connectivity issue, and to prevent bumping in these cases. This can help avoid the situation where RPC nodes are not propagating transactions for some non-price-related reason (e.g. go-ethereum bug, networking issue etc) and bumping gas would not help.

Set to zero to disable connectivity checking completely.

CheckInclusionPercentile

CheckInclusionPercentile = 90 # Default

CheckInclusionPercentile controls the percentile that a transaction must have been higher than for all the blocks in the inclusion check window in order to register as a connectivity issue.

For example, if CheckInclusionBlocks=12 and CheckInclusionPercentile=90 then further bumping will be prevented for any transaction with any attempt that has a higher price than the 90th percentile for the most recent 12 blocks.

EIP1559FeeCapBufferBlocks

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

EIP1559FeeCapBufferBlocks = 13 # Example

EIP1559FeeCapBufferBlocks controls the buffer blocks to add to the current base fee when sending a transaction. By default, the gas bumping threshold + 1 block is used.

Only applies to EIP-1559 transactions)

TransactionPercentile

TransactionPercentile = 60 # Default

TransactionPercentile specifies gas price to choose. E.g. if the block history contains four transactions with gas prices [100, 200, 300, 400] then picking 25 for this number will give a value of 200. If the calculated gas price is higher than GasPriceDefault then the higher price will be used as the base price for new transactions.

Must be in range 0-100.

Only has an effect if gas updater is enabled.

Think of this number as an indicator of how aggressive you want your node to price its transactions.

Setting this number higher will cause the Chainlink node to select higher gas prices.

Setting it lower will tend to set lower gas prices.

EVM.HeadTracker

[EVM.HeadTracker]
HistoryDepth = 100 # Default
MaxBufferSize = 3 # Default
SamplingInterval = '1s' # Default

The head tracker continually listens for new heads from the chain.

In addition to these settings, it log warnings if EVM.NoNewHeadsThreshold is exceeded without any new blocks being emitted.

HistoryDepth

HistoryDepth = 100 # Default

HistoryDepth tracks the top N block numbers to keep in the heads database table. Note that this can easily result in MORE than N records since in the case of re-orgs we keep multiple heads for a particular block height. This number should be at least as large as FinalityDepth. There may be a small performance penalty to setting this to something very large (10,000+)

MaxBufferSize

MaxBufferSize = 3 # Default

MaxBufferSize is the maximum number of heads that may be buffered in front of the head tracker before older heads start to be dropped. You may think of it as something like the maximum permittable "lag" for the head tracker before we start dropping heads to keep up.

SamplingInterval

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

SamplingInterval = '1s' # Default

SamplingInterval means that head tracker callbacks will at maximum be made once in every window of this duration. This is a performance optimisation for fast chains. Set to 0 to disable sampling entirely.

SyncThreshold

SyncThreshold = 5 # Default

SyncThreshold controls how far a node may lag behind the best node before being marked out-of-sync. Depending on SelectionMode, this represents a difference in the number of blocks (HighestHead, RoundRobin, PriorityLevel), or total difficulty (TotalDifficulty).

Set to 0 to disable this check.

LeaseDuration

LeaseDuration = '0s' # Default

LeaseDuration is the minimum duration that the selected "best" node (as defined by SelectionMode) will be used, before switching to a better one if available. It also controls how often the lease check is done. Setting this to a low value (under 1m) might cause RPC to switch too aggressively. Recommended value is over 5m
