Proxy contracts tronbox tailored demo

[simbadMarino]

Hello tronbox team, sorry if this is not the best place to ask, is there a repo we can use as an example to deploy and upgrade proxy and implementation contracts ? Thanks !

if i need use:

import "@openzeppelin/contracts/proxy/transparent/TransparentUpgradeableProxy.sol";

i need use a solc version 0.8.21 and tronbox has a maxversion 0.8.20:

Error parsing @openzeppelin/contracts/proxy/ERC1967/ERC1967Utils.sol: ParserError: Source file requires different compiler version (current compiler is 0.8.20+commit.5f1834bc.Emscripten.clang) - note that nightly builds are considered to be strictly less than the released version
--> ParsedContract.sol:4:1:

Compilation failed. See above.

@lopeed The next version will support 0.8.21. For now you can use npm i @openzeppelin/[email protected] first
