> Arc API method that returns the sync status of the node. Returns false if the node is fully synced, or a sync status object if syncing.

Arc API method that returns the sync status of the node. Returns `false` if the node is fully synced, or a sync status object if syncing.

## Parameters

* `none`

## Response

* `result` — `false` if not syncing, or a sync status object:
  * `startingBlock` — block at which sync started
  * `currentBlock` — current block being synced
  * `highestBlock` — estimated highest block

  ```javascript ethers.js theme={"system"}
  const { ethers } = require("ethers");
  const NODE_URL = "CHAINSTACK_NODE_URL";
  const provider = new ethers.JsonRpcProvider(NODE_URL);

  async function checkSyncStatus() {
    const syncing = await provider.send("eth_syncing", []);
    if (syncing === false) {
      console.log("Node is fully synced");
    } else {
      console.log(`Syncing: ${Number(syncing.currentBlock)}/${Number(syncing.highestBlock)}`);
    }
  }

  checkSyncStatus()
  ```

  ```python web3.py theme={"system"}

  syncing = web3.eth.syncing
  if syncing is False:
      print("Node is fully synced")
  else:
      print(f"Syncing: {syncing['currentBlock']}/{syncing['highestBlock']}")
  ```
