This post is regarding to the total supply of SHIB, most of the people rely on third parties entities to get their numbers and information, thus making them susceptible to being manipulated with fake and ill intended information. If you combine this with the lack of technical background for a lot of people you can see how most people succumb to fear, uncertainty and doubt (FUD).
With the previously mentioned premise, I decided to go to the source directly, which is the SHIB smart contract address: 0x95aD61b0a150d79219dCF64E1E6Cc01f0B64C4cE verifiable at https://etherscan.io/.
In etherscan if you copy the SHIB smart contract address to the search bar, it will take you directly to its smart contract. There you will notice 8 tabs:
Transactions Internal Txns Erc20 Token Txns Contract Events Analytics Info Comments
If you select Contract, you can see 3 sub tabs:
Code Read Contract Write Contract
In the Code sub tab, if you copy the code and check for mint options, you can see that the mint option for the token is only and I MEAN ONLY called from the constructor of the smart contract, what does this mean? That the amount of supply is fixed to the amount selected at the deployment of the SHIB smart contract. In simpler words, new coins can not be added or in another words the supply is LIMITED/FIXED.
Now, if you go to the read contract sub tab, here you can check the functionalities that the SHIB smart contract offers for free, since these are read only functions and does not modify the state of the ethereum blockchain.
Continuing with the read contract sub tab, if you check balanceOf option and type the dead wallet 0xdead000000000000000042069420694206942069, you can check how much SHIB does that account has, which is 410254269653826829720489367534651 at the writing of this post. That account is a DEAD WALLET, period, no buts, even ETHERSCAN has marked it as such.
If you check the totalSupply function, you can check the total supply of SHIB, which is 999992392581199783685833285409628 at ANY POINT IN TIME (IT CAN NOT INCREASE).

I hope with this, people can verify directly from the source the total supply and stop relying on information from third parties entities.
