Parameters

Parameter	Type	Required	Description
config	object	No	Optional configuration object. See fields below.
config.commitment	string	No	Desired finality level for the query. Accepted values: `processed`, `confirmed`, `finalized` (default).
config.minContextSlot	number	No	The minimum slot at which the request may be evaluated.

commitment values

Value	Description
processed	Return data from the highest slot this node has processed on the fork it currently considers best. This is the newest view, but it can still change if the cluster switches forks.
confirmed	Return data from the highest slot that at least two-thirds of active stake has directly voted to confirm. More stable than processed, but a weaker guarantee than finalized.
finalized	Return data from the highest slot that the cluster recognizes as finalized. The slot has reached maximum vote lockout in validators' vote towers and is recognized by at least two-thirds of active stake. This is the strongest commitment level.
