Token totalsupply displaying zero at etherscan but displays correctly at remix

Question

I verified and deployed a token contract using remix. The totalsupply displays correctly 80000000000 but at etherscan it displays the totalsupply as 0.0000000008.

Summary [ERC-20] Total Supply: 0.00000011 WIMT ($0.00) Price: $0.0000 @ 0.000000 Eth

here is the link https://etherscan.io/token/0x258c6b5e54565a20d925c4b9cdbd97239e3ac3bf

but at etherscan here it displays correctly

We found a Contract With ERC-20 Token Transfer Events

Token 0x258c6b5e54565a20d925c4b9cdbd97239e3ac3bf On-chain Token Attributes Check Result: Total Supply = 110000000000 Name = WIMT Symbol = WIMT Decimals = 18 ERC-165 Interface = {Not Available} Implements ERC-721 = No

here is the link https://etherscan.io/tokens?q=0x258c6b5e54565a20d925c4b9cdbd97239e3ac3bf

How do i correct this without redeploying the contract? Thank for your help.

Answer 1

This is happening because of this line : totalSupply = _totalSupply;

You forgot to multiple it with the decimals. Changing it to totalSupply = _totalSupply * (10 ** uint256(decimals)) can make it as per the requirement.

You can see an example here: https://github.com/OpenZeppelin/openzeppelin-solidity/blob/master/contracts/examples/SimpleToken.sol

I don't think that there is any way to improve it with redeploying the contract.
