Common proxy vulnerabilities in Solidity – part 2
In the previous part, we explained some of typical proxy issues related to initialization, lack of state update or frontrunning. In this part, we would like to talk a bit about function and storage conflicts and also about decentralization. Proxy function clashing This vulnerability is unlikely to be found unless the proxy is a custom […]
Common proxy vulnerabilities in Solidity part 1
Proxies are used to implement upgradeability in Solidity smart contracts. They serve as a middleman between a contract and its users. They are employed to change a contract’s logic without altering its address. A master copy contract and a proxy contract that refers to the master copy are how proxies are typically set up. A […]
