Assets sent to a contract after selfdestruct are lost in most cases checking that contract is not selfdestructed before the transfer does not help much because transfer may be frontrunned with selfdestruct It allows modifying bytecode of a deployed smart contract (EIP-1014)

 

Introduction to Smart Contracts A Simple Smart Contract Let us begin with a basic example that sets the value of a variable and exposes it for other contracts to access. It is fine if you do not understand everything right now we will go into more details later. Storage Example open in Remix

 

Since the CREATE2 Op-Code was introduced you can pre-compute a contract address. I was talking about this extensively in the Proxy contract minicourse. If you are interested - head over to the mini-course section! Warning: it is quite advanced though? Without CREATE2 a contract gets deployed to an address that is computed based on your address + your nonce. That way it was guaranteed that ...

 

The selfdestruct function is provided by Ethereum smart contracts to destroy a contract on the blockchain system. However it is a double-edged sword for developers. On the one hand using selfdestruct function enables developers to remove smart contracts (SC) from Ethereum and transfers Ethers when emergency situations happen e.g. being attacked. On the other hand this function can increase ...

 

In a 2021 research paper "Why Do Smart Contracts Self-Destruct? Investigating the Selfdestruct Function on Ethereum" around 800 contracts have included the selfdestruct keyword making it an important concept to understand while studying Solidity.
