eth_getBlockTransactionCountByHash JSON-RPC method

To use eth_getBlockTransactionCountByHashmethod you need to be connected to an Ethereum node either a remote one through services like CHAINNODES (opens in a new tab) or a local one.


Block trasaction count - the number of transactions in the block with the given block hash.


If the specified block hash does not exist in the blockchain, the eth_getBlockTransactionCountByHash will return null.


block hash - String - The hash of the block (32 bytes)
