Hi I am working on the auction app in block chain using solidity as smart contract in Ethereum.The requirements are. The DAPP will ask for the auction in the public domain like for example selling an iPhone; All the users will bid for the item; The smart contract will find the winner based on the highest money and declare him as the winner. Solidity libraries can indeed selfdestruct Solidity libraries are just contracts, no different from ordinary contracts, just that they are meant to be used with delegatecall rather than call . When the Solidity compiler compiles a library it prohibits it from using storage—except via storage parameters or inline assembly—but it does not prohibit selfdestruct.
In the following Solidity inheritance example, a destruction request was sent. See the outcome of it in here and read the related article too. The selfdestruct(address)function, removes all bytecode from the contract address and sends all ether stored to the specified address. If this specified address is also a contract, no functions (including the fallback) get called.
Solidity knows two kinds of function calls: external ones that do create an actual EVM message call and internal ones that do not. Furthermore, internal functions can be made inaccessible to derived contracts. This gives rise to four types of visibility for functions. external External functions are part of the contract interface,. Events. In Solidity, we define events, and then emit them.

selfdestruct function deletes the instance of the smart contract from the blockchain and before it does transfers all the remaining ETH stored in it to the address passed as an argument. Let us understand this better with an example. selfdestruct ("address_to_send_ETH_before_deletion"); The Game
