Response

JSON

Example

{
  "jsonrpc": "2.0",
  "id": 1,
  "result": "728126428"
}

net_version returns the network identifier as a decimal string. The response is a string even though it contains only decimal digits.

Use it for compatibility with clients that still inspect the net namespace. For modern EVM chain selection, eth_chainId exposes the same identifier using the standard hexadecimal quantity representation.

Parameters

JSON-RPC params must be an empty array.

paramsarrayrequired

Empty array; this method accepts no positional parameters.

Response

Response fields

Field	Type	Description
`jsonrpc`	string	JSON-RPC protocol version.
`id`	number	Correlates the response with the request.
`result`	string	Network identifier in decimal notation.

Errors

See Tron errors for the shared envelope.

Code	Meaning	When it happens
`-32602`	Invalid params	A positional parameter was supplied.
`-32601`	Method not found	The method is not in the published Tron catalog.
`401`	Unauthorized	The API key is missing or invalid.
`429`	Rate limited	The `tron_read_rpc` budget is exceeded.

Examples

JavaScript

const response = await fetch("https://triport.io/rpc/tron", {
  method: "POST",
  headers: { "x-token": process.env.TRIPORT_API_KEY, "Content-Type": "application/json" },
  body: JSON.stringify({ jsonrpc: "2.0", id: 1, method: "net_version", params: [] }),
});
console.log((await response.json()).result);

Notes

Do not interpret the result as a hexadecimal quantity.
The measured mainnet response is "728126428".
