Fantom API method that returns an object with information about the current synchronization status of the node, or false if the node is fully synced. This method can track the progress of a node’s synchronization with the Fantom blockchain. The returned object contains data such as the starting block, current block, and highest block of the node, allowing developers to monitor and estimate the time remaining for the node to sync fully.

eth_syncing code examples

const { Web3 } = require("web3");
const NODE_URL = "CHAINSTACK_NODE_URL";
const web3 = new Web3(NODE_URL);

async function syncStatus() {
  const status = await web3.eth.isSyncing();
  console.log(status)
}

syncStatus()

​
Use case

The eth_syncing method can be useful for developers building applications that interact with the Fantom blockchain. For example, you may want to provide feedback to your application’s user about the status of the node the application is connecting to.
