Uplift security record

A reentrancy attack can occur when the contract creates a function that makes an external call to another untrusted contract before resolving any effects. If the attacker can control the untrusted contract, they can make a recursive call back to the original function, repeating interactions that would have otherwise not run after the external call resolved the effects. ### External call(s) ```solidity=109 IERC20(token).safeTransfer(account_, amountInBuyToken); ``` ### State variables written after the call(s) ```solidity=110 refundClaimedInBuyToken[token][identifier][account_] += amountInBuyToken; ``` --- ### External call(s) ```solidity=55 IERC20(token_).safeTransfer(msg.sender, availableForWithdrawInIDOTokens); ``` ### State variables written after the call(s) ```solidity=56 claimed[token_][identifier_][msg.sender] += availableForWithdrawInIDOTokens; ```
