## Parameters

* `none` — This method does not require any parameters.

## Response

* `result` — an object containing syncing details if the node is syncing; otherwise, `false`. The object includes:
  * `startingBlock` — the block number where the sync started.
  * `currentBlock` — the block number where the node is currently synced to.
  * `highestBlock` — the highest block number known in the chain that the node is syncing towards.

If the node is not syncing, the result will be `false`.

## Use case

The `eth_syncing` method is useful for:

* Monitoring tools and services that track the sync status of Base nodes.
* Developers and users who want to check if a node is fully synced before making transactions or deploying contracts.
