Response

JSON

Example

{
  "jsonrpc": "2.0",
  "id": 1,
  "result": "0x2b6653dc"
}

eth_chainId identifies the EVM-compatible Tron mainnet represented by this endpoint. The value is encoded as an EVM hex quantity and is suitable for network checks in EVM tooling.

Use it to reject an incorrectly configured endpoint before reading state. It is the hexadecimal form of the same numeric identifier returned as a decimal string by net_version.

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	Chain identifier as an EVM hex quantity.

Errors

See Tron errors for the common error envelope.

Code	Meaning	When it happens
`-32602`	Invalid params	A positional parameter was supplied.
`-32601`	Method not found	The requested method is not in the 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: "eth_chainId", params: [] }),
});
console.log(BigInt((await response.json()).result));

Notes

The measured mainnet value is 0x2b6653dc.
Do not substitute Ethereum chain IDs when configuring EVM libraries for Tron.
Related: net_version returns the identifier in decimal notation.
