This is a sample repo illustrating an attempt to verify UUPS proxy deployed as described
in OZ UUPS tutorial
npx hardhat test
Shmoken Upgrade
Owner = 0xf39Fd6e51aad88F6F4ce6aB8827279cffFb92266
Owner Balance in V1 = 1000000000000000000000
Owner Balance in V2 = 1000000000000000000000
New value existing only in V2 before being initialized = 0x0000000000000000000000000000000000000000
New value existing only in V2 after being initialized = 0x1111111111111111111111111111111111111111

Compilation finished successfully
Error in plugin @nomiclabs/hardhat-etherscan: The address provided as argument contains a contract, but its bytecode doesn't match any of your local contracts.
Possible causes are:
- Contract code changed after the deployment was executed. This includes code for seemingly unrelated contracts.
- A solidity file was added, moved, deleted or renamed after the deployment was executed. This includes files for seemingly unrelated contracts.
- Solidity compiler settings were modified after the deployment was executed (like the optimizer, target EVM, etc.).
- The given address is wrong.
- The selected network (rinkeby) is wrong.https://hardhat.org/plugins/nomiclabs-hardhat-etherscan.html#using-programmatically
