Response

JSON

Example

{
  "jsonrpc": "2.0",
  "id": 1,
  "result": "0x51e650e"
}

eth_blockNumber returns the number of the latest block visible to the selected Tron JSON-RPC node. The result uses the EVM quantity format: a 0x-prefixed hexadecimal string with no unnecessary leading zeroes.

Use this method to establish a current head before requesting blocks or bounded log ranges. It reports a height, not a complete block; use eth_getBlockByNumber when block data is required.

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	Latest block number as an EVM hex quantity.

Errors

See Tron errors for the shared envelope and routing behavior.

Code	Meaning	When it happens
`-32602`	Invalid params	`params` is not empty or the request shape is invalid.
`-32601`	Method not found	The requested method is outside the published Tron catalog.
`401`	Unauthorized	The `x-token` header is missing or invalid.
`429`	Rate limited	The `tron_read_rpc` budget is exceeded.

Examples

JavaScript

const body = { jsonrpc: "2.0", id: 1, method: "eth_blockNumber", params: [] };
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(body),
});
console.log((await response.json()).result);

Notes

Convert the result with BigInt(result) when a decimal height is needed.
Tron has no WebSocket head subscription on this product surface; poll this method at an interval that fits the tier budget.
