Hello thanks for the good article. uint256 unsoldTokens = totalTokensForSale - alreadyMinted; if (unsoldTokens > 0 ) { tokensForEcosystem = tokensForEcosystem + unsoldTokens; } Just because of these 3 lines I am getting error : could potentially lead to re-entrancy vulnerability. <br/><i>Note:</i> Modifiers are currently not considered by this static analysis.

I am also looking for the same.

How can we get the abi of this contract ?

Is necessary to use metamask with infura ?
