How to self-destruct a smart contract. What is the syntax of the code. Will self-destructing my smart contract will refund me any ether from the network?
The syntax for selfdestruct is simple:
addr is the address where possible Ether balance of the contract is sent.
You will not receive a refund for the selfdestruct, since the recent London hard fork removed gas refund for selfdestruct (https://eips.ethereum.org/EIPS/eip-3529).
