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.


curl https://bsc-<network> 
-H "Content-Type: application/json"  
-d "{\"jsonrpc\":\"2.0\",\"method\":\"eth_getUncleByBlockNumberAndIndex\",\"params\": [\"0x29c\",\"0x0\"],\"id\":1}" 
  1. BLOCK PARAMETER - An int block number in the form of hex, appended with 0x such as 0x6D7FE0, or pre-defined strings latest, earliest, pending.

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

Web3API's Composer accepts int block numbers, which will be auto-converted to a hex representation before being sent to a node.
