eth_syncing code examples

ethers.js

const { ethers } = require("ethers");

const provider = new ethers.JsonRpcProvider("CHAINSTACK_NODE_URL");

async function checkSyncStatus() {
  const syncStatus = await provider.send("eth_syncing", []);
  if (syncStatus === false) {
    console.log("Node is fully synced");
  } else {
    console.log(`Syncing: ${parseInt(syncStatus.currentBlock, 16)} / ${parseInt(syncStatus.highestBlock, 16)}`);
  }
}

checkSyncStatus();

Use case

A practical use case for eth_syncing is implementing health checks in your application to ensure the node is fully synced before processing transactions or queries that require the latest chain state.
