getSlotLeader

Last updated:

getSlotLeader returns a single Pubkey — the base-58 encoded identity public key of the validator scheduled to produce the block for the slot currently being processed by the node.

Use it for a quick, point-in-time answer to "who is leader right now?" — for example to label live transaction routing or to surface the active validator in a dashboard. The result reflects the slot resolved at the requested commitment level, so it tracks the leader as the cluster advances.

To look up leaders for a range of upcoming slots rather than just the current one, use getSlotLeaders, or fetch the full epoch schedule with getLeaderSchedule.

All Solana JSON-RPC methods POST to the same base path /v1/sol; the method field in the request body selects the call.
