eth_syncing RPC method



eth_syncing always returns "false" when using CHAINNODES.ORG (opens in a new tab) as our nodes are always synced for you.

  • Boolean or object false if the node is in sync otherwise it's true with:

    • startingblock - The block at which the import started encoded as hexadecimal.

    • currentblock - The current block, same as eth_blockNumber encoded as hexadecimal.

    • highestblock - The estimated highest block encoded as hexadecimal.

  "jsonrpc": "2.0",
  "id": 1,
  "result": "false"
