In this work, we provide a comprehensive survey of smart contract
upgradability patterns using proxies. A primary characteristic of smart
contracts on the Ethereum blockchain is that they are immutable once
implemented, no changes can be made. Taking human error into account, as well
as technology improvements and newly discovered vulnerabilities, there has been
a need to upgrade these smart contracts, which may hold enormous amounts of
Ether and hence become the target of attacks. Several such attacks have caused …
