Fetching the pending header is not supported - eth_call(pending) unsupported

[dankostiuk]

JSON-RPC Method not available

Description

JSON-RPC calls that include the "pending" block tag such as eth_call are not supported. For example:

{"jsonrpc": "2.0", "method": "eth_call", "params": [{"to": "0x2d8CD9969597A67829aEb63e953fB791401dc4C2", "data": "0xa0e67e2b"}, "pending"], "id": 180}

gives the response:

{
    "jsonrpc": "2.0",
    "id": 1,
    "error": {
        "code": -32600,
        "message": "fetching the pending header is not supported"
    }
}

As the pending block tag is used by many dApps, it would be greatly appreciated if this call could be supported.

Environment

• Ubuntu 20
• Polygon-Edge 0.1.0

Hi @dankostiuk ,

This answer comes a bit late, I apologize for this. At the moment, it is true that Polygon Edge does not support the pending block tag, and we don't know yet if we'll add it in the future.
If we'll do, I will give you an update here.
