Question

How to verify proxy on https://attractive-merope.explorer.staging-v2.skalenodes.com/address/0x19933c2ffb1c1aD6e124406A91D87C49C2F113C0/contracts

The proxy information is in deployments/skaletest/TestContract_Proxy.json created by hardhat-deploy plugin (https://github.com/wighawag/hardhat-deploy)

For example, args of the contructor:

"args": [
  "0x6B187a7b4439FD0C8128D72EB79Ef621AC6A60cc",
  "0xC689b663E0d0E66465e3E7dfC4777E007A3567E6",
  "0x"
],

The flattened contract of the proxy is in contracts-flat/TransparentUpgradeableProxy-flat.sol. The flattened contract was generated by hardhat flatten command on open zeppelin upgradeable proxy contract used by the plugin and copied to OZ folder.
