Response

JSON

Example

{
  "jsonrpc": "2.0",
  "id": 1,
  "result": "56"
}

net_version returns the BNB Smart Chain network identifier as an unprefixed decimal string.

Use it for compatibility with clients that still consume the net namespace. The example returns 56 for BNB Smart Chain mainnet.

Unlike eth_chainId, the value is not an EVM hex quantity. New chain-selection logic should generally prefer eth_chainId.

Parameters

JSON-RPC params must be an empty array: [].

Response

The response below is the checked fixture for this method; it is reproduced without changing its fields or values.

resultstring (decimal integer)

Network identifier as a decimal string.

Errors

Errors use the standard JSON-RPC error envelope. See BSC errors for network-specific classification and the linked shared reference.

Code	Meaning	When it happens
`-32602`	Invalid params	A required positional parameter is missing or a value does not match the OpenRPC schema.
`401`	Unauthorized	The `x-token` API key is missing or invalid.
`429`	Rate limited	The request exceeds the configured category RPS for the caller's tier.

const payload = await response.json();
console.log(payload.result);

Notes

The BSC categories use configured defaults of 15 / 20 / 100 / 250 RPS; they are marked unmeasured in the tier matrix.
