Example of https://github.com/radeksvarz/erc1967uupsentrypoint - the lightweight ERC-1967 proxy implementation.
Having 2 step deploy script using Create-X CREATE3 https://github.com/radeksvarz/createx-forge for deterministic entrypoint proxy address immune to solc / mbor / source code comment changes in time.
Deployed on Sepolia: https://eth-sepolia.blockscout.com/address/0xC0bf4d3F67B0B516930B28A90fe4022F20bEbE96?tab=contract
Beware of setting up proper --sender when invoking forge script, otherwise deployed address does not match.
Example Implementation uses ERC-7201 storage to mitigate upgrade storage collision issues / hacks.
