Preventing re-entrancy attacks in Solidity
Re-entrancy is a vulnerability in smart contracts that can result in unexpected behavior and loss of funds. This vulnerability enables an attacker to execute a function call repeatedly before the original call has completed. Therefore, re-entrancy can change the contract’s state in unforeseen ways and trigger unintended operations. This can lead to significant security risks, […]

Preventing Denial of Service Attacks in Solidity
Solidity security is a critical concern for anyone building smart contracts on the Ethereum blockchain. One of the biggest security risks for contracts is the potential for Denial of Service (DoS) attacks. Malicious users can intentionally cause a smart contract to consume more resources than intended, or make it unresponsive, unavailable or cause calls to […]
