BNB Smart Chain method

net_version

Returns the network ID as a decimal string. Superseded by eth_chainId.

cheapCheap for a provider to serve — no state is read, or one key is.Primary specification

How each provider handles it

This method has not been measured in this window.

It is in the catalogue but disabled, so nothing calls it.

What it does

The original network identifier, predating EIP-155. It returns a decimal string where `eth_chainId` returns a hex quantity.

They are the same number on every major network today, but they are not the same field, and `eth_chainId` is the one to use.

Returns

String — the network ID in decimal.

Try it

Runnable as written, against a keyless public endpoint. Nothing here needs an API key.

Request

curl -s https://ethereum-rpc.publicnode.com \
  -H 'content-type: application/json' \
  -d '{"jsonrpc":"2.0","method":"net_version","params":[],"id":67}'

As JSON-RPC

{
  "jsonrpc": "2.0",
  "method": "net_version",
  "params": [],
  "id": 67
}

Response

{
  "id": 67,
  "jsonrpc": "2.0",
  "result": "1"
}

Things that bite

Decimal "1", not hex "0x1". Code that compares the two without converting will silently disagree.

Why it is measured

Kept as a legacy compatibility check and disabled by default, since almost nothing should still be reading it.

Called every 900 seconds per endpoint, with jitter so the fleet does not hit a provider in lockstep.
