UUPS Proxy Pattern Implementation

It allows us to upgrade previously deployed contracts for timely updates. Comparetively cheaper than TransparentUpgradeable Proxy pattern.

In simple words, it works as follows :

  • upgradeProxy() is applied to deploy ERC1967 Proxy which delegates all calls to the implementation as well the functionality to upgrade to a newer implementation.
  • Unlike TransparentUpgradeable Proxy It doesn't have ProxyAdmin for upgrade functionality due to which it's cheaper for deployments.

For detailed difference between proxy patterns, feel free to check out this repository README file.
