[Transaction] klay_call

Executes a new message call immediately without creating a transaction on the block chain. It returns data or an error object of JSON RPC if error occurs.

If you deployed a contract, use klay_getTransactionReceipt to get the contract address.

NOTE In versions earlier than Kaia v1.7.0, only integer block number, the string "earliest" and "latest" are available.
