Universal Upgradeable Proxy Standard (UUPS) - ERC-1822

Reference: https://eips.ethereum.org/EIPS/eip-1822

• First, deploy your logic contract:

forge create src/MyContract.sol:MyContract --private-key YOUR-PRIVATE-KEY  

• Then deploy your proxy contract:

forge create src/Proxy.sol:Proxy --private-key YOUR-PRIVATE-KEY --constructor-args 0x2e147cba ADDRESS-LOGIC-CONTRACT

• Now you can manipulate thought proxy contract:

cast send 0xb19b36b1456E65E3A6D514D3F715f204BD59f431 "increment()" --private-key YOUR-PRIVATE-KEY  

• If you need update your logic contract:

cast send ADDRESS-PROXY-CONTRACT "updateCode(address)" NEW-ADDRESS-LOGIC-CONTRACT --private-key YOUR-PRIVATE-KEY
