Let’s begin with where this all started. One or two weeks ago someone noticed on etherscan that the circulation supply was over 210 million tokens when you view the top 500 holders of the COSS token, like you all probably know the total token supply was supposed to be max 200 million.

​

People started asking questions and were doing their own investigation. Since this is crypto and all data is public on the Ethereum chain, everyone can look into it. Since i’m also a COSS token holder I started taking a look with a friend in what was going on. First I checked all original ICO addresses of the original ERC20 contract, everything looked clean on that.

Then I started checking the new ERC223 contract and I noticed a weird function, this was called “TokenReplaceFix” https://etherscan.io/address/0x9e96604445ec19ffed9a5e8dd7b50a29c899a10c#code , which was used in the new ERC223 contract, but in a ERC223 test contract they had deployed a day earlier the function wasn’t in there. That’s why it catches my eye, I didn’t knew how important it was yet.

I started checking historical balances of COSS.io main wallet, I noticed a sudden increase from beginning of 6th June all up to 12th June. The increase was from 47 million tokens to 71 millions tokens. Of course you could think some big whales joined, but that didn’t happen. There were no incoming transactions in the COSS wallet to reflect such a large amount (25 million) of tokens. As can be seen here
