# jsonrpc eth_syncing | TRON

> TRON API method that returns an object describing the sync status or false if not syncing, using Ethereum-compatible JSON-RPC format.

TRON API method that returns an object describing the sync status or false if not syncing, using Ethereum-compatible JSON-RPC format. This method provides Ethereum tooling compatibility for synchronization status monitoring on TRON.

## Parameters

* `jsonrpc` — the JSON-RPC protocol version (always "2.0")
* `method` — the method name (always "eth\_syncing")
* `params` — parameters array (empty for this method)
* `id` — request identifier (number or string)

## Response

* `jsonrpc` — the JSON-RPC protocol version ("2.0")
* `id` — the request identifier that matches the request
* `result` — sync status object with startingBlock, currentBlock, highestBlock fields, or false if not syncing

## Use case

The `jsonrpc eth_syncing` method is used for:

* Monitoring blockchain synchronization status with Ethereum-compatible tools
* Supporting node health checks and monitoring applications on TRON
* Enabling Ethereum-based infrastructure monitoring tools to work with TRON
* Providing sync status information for wallet and dApp integration
