Added

New optional external logger added

AUDIT_LOGGER_FORWARD_TO_URL
  • Default: none

When set, this environment variable configures and enables an optional HTTP logger which is used specifically to send audit log events. Audit logs events are emitted when specific actions are performed by any of the users through the node's API. The value of this variable should be a full URL. Log items will be sent via POST

There are audit log implemented for the following events:

  • Auth & Sessions (new session, login success, login failed, 2FA enrolled, 2FA failed, password reset, password reset failed, etc.)
  • CRUD actions for all resources (add/create/delete resources such as bridges, nodes, keys)
  • Sensitive actions (keys exported/imported, config changed, log level changed, environment dumped)

A full list of audit log enum types can be found in the source within the audit package (audit_types.go).

The following AUDIT_LOGGER_* environment variables below configure this optional audit log HTTP forwarder.

AUDIT_LOGGER_HEADERS
  • Default: none

An optional list of HTTP headers to be added for every optional audit log event. If the above AUDIT_LOGGER_FORWARD_TO_URL is set, audit log events will be POSTed to that URL, and will include headers specified in this environment variable. One example use case is auth for example: AUDIT_LOGGER_HEADERS="Authorization||{{token}}".

Header keys and values are delimited on ||, and multiple headers can be added with a forward slash delimiter ('\'). An example of multiple key value pairs:
AUDIT_LOGGER_HEADERS="Authorization||{{token}}\Some-Other-Header||{{token2}}"

AUDIT_LOGGER_JSON_WRAPPER_KEY
  • Default: none

When the audit log HTTP forwarder is enabled, if there is a value set for this optional environment variable then the POST body will be wrapped in a dictionary in a field specified by the value of set variable. This is to help enable specific logging service integrations that may require the event JSON in a special shape. For example: AUDIT_LOGGER_JSON_WRAPPER_KEY=event will create the POST body:

{
  "event": {
    "eventID":  EVENT_ID_ENUM,
    "data": ...
  }
}

Automatic connectivity detection; Chainlink will no longer bump excessively if the network is broken

This feature only applies on EVM chains when using BlockHistoryEstimator (the most common case).

Chainlink will now try to automatically detect if there is a transaction propagation/connectivity issue and prevent bumping in these cases. This can help avoid the situation where RPC nodes are not propagating transactions for some reason (e.g. go-ethereum bug, networking issue etc) and Chainlink responds in a suboptimal way by bumping transactions to a very high price in an effort to get them mined. This can lead to unnecessary expense when the connectivity issue is resolved and the transactions are finally propagated into the mempool.

This feature is enabled by default with fairly conservative settings: if a transaction has been priced above the 90th percentile of the past 12 blocks, but still wants to bump due to not being mined, a connectivity/propagation issue is assumed and all further bumping will be prevented for this transaction. In this situation, Chainlink will start firing the block_history_estimator_connectivity_failure_count prometheus counter and logging at critical level until the transaction is mined.

The default settings should work fine for most users. For advanced users, the values can be tweaked by changing BLOCK_HISTORY_ESTIMATOR_CHECK_INCLUSION_BLOCKS and BLOCK_HISTORY_ESTIMATOR_CHECK_INCLUSION_PERCENTILE.

To disable connectivity checking completely, set BLOCK_HISTORY_ESTIMATOR_CHECK_INCLUSION_BLOCKS=0.

Changed

  • The default maximum gas price on most networks is now effectively unlimited.

    • Chainlink will bump as high as necessary to get a transaction included. The connectivity checker is relied on to prevent excessive bumping when there is a connectivity failure.
    • If you want to change this, you can manually set ETH_MAX_GAS_PRICE_WEI.

  • EVMChainID field will be auto-added with default chain id to job specs of newly created OCR jobs, if not explicitly included.

    • Old OCR jobs missing EVMChainID will continue to run on any chain ETH_CHAIN_ID is set to (or first chain if unset), which may be changed after a restart.
    • Newly created OCR jobs will only run on a single fixed chain, unaffected by changes to ETH_CHAIN_ID after the job is added.
    • It should no longer be possible to end up with multiple OCR jobs for a single contract running on the same chain; only one job per contract per chain is allowed
    • If there are any existing duplicate jobs (per contract per chain), all but the job with the latest creation date will be pruned during upgrade.

Fixed

  • Fixed minor bug where Chainlink would attempt (and fail) to estimate a tip cap higher than the maximum configured gas price in EIP1559 mode. It now caps the tipcap to the max instead of erroring.
  • Fixed bug whereby it was impossible to remove eth keys that had extant transactions. Now, removing an eth key will drop all associated data automatically including past transactions.
