eth_getUncleByBlockNumberAndIndex

Returns information about the 'Uncle' of a block by number and the Uncle index position.

While this method is supported, the BSC network uses the Proof of Staked Authority ( PoSA ) consensus mechanism which doesn't involve 'Uncle' blocks.

Hence all results from eth_getUncleByBlockNumberAndIndex will always return 0x0.

Request Parameters

2. UNCLE INDEX POSITION - a hex of the integer representing the uncle's index position in the block, appended with 0x such as 0x0.
