This is `initialize` function of my upgradeable contract ```auto contract MyContract is Initializable, ERC20PresetMinterPauserUpgradeable, OwnableUpgradeable { function initialize(string memory _name, string memory _symbol) public override initializer { emit ContractInitStarted(_name, _symbol, msg.sender, block.timestamp); __ERC20PresetMinterPauser_init(_name, _symbol); __Ownable_init_unchained(); _mint(msg.sender, 500000000 ether); emit ContractInitEnded(_name, _symbol, msg.sender, block.timestamp); } } ``` This is `2_deploy_contracts.js` ```auto const MyContract = artifacts.require("./MyContract .sol"); const { deployProxy } = require("@openzeppelin/truffle-upgrades"); module.exports = async function (deployer) { await deployProxy(MyContract , ["MyContract 1.0", "TenX"], { deployer, initializer: "initialize" }); }; ``` `npx truffle deploy --network rinkeby` Initialize function is never invoked. symbol, name and totalSupply are empty ---

How are you checking `symbol`, `name` and `totalSupply`? ---

And how are you picking the address to which call `totalSupply()`? Maybe you’re using the implementation instead of the proxy address? ---

I can see it in my address transaction in etherscan and also during deployment there’s an output with contracts name and address ---

Hi @dmdv, Etherscan shows your token name, symbol and decimals. > **[MyToken Token 1.0 (TenX) Token Tracker | Etherscan](https://rinkeby.etherscan.io/token/0xe97ef53dd413729425317a768a0ba425831c5107)** > > MyToken Token 1.0 (TenX) Token Tracker on Etherscan shows the price of the Token $0.0000, total supply 500,000,000, number of holders 1 and updated information of the token.

Hi @dmdv, With upgradeable contracts, we interact with the proxy and not with the implementation contract, or to put it another way, we use the ABI of the implementation contract to interact with the proxy at the address of the proxy. The proxy contract on Etherscan shows the name, symbol, decimal etc as I would expect. I am not sure what the issue is? ---

@abcoathup I followed the instruction you’d posted before and it worked. Thanks. But the question is still there - why I couldn’t see any events from initialize function ---
