Use of transfer() instead of call() to send eth

Lines of code Vulnerability details Use of transfer instead of call to send eth Impact OZSafeERC20.safeTransfer relies on transfer at the end, but with a check of the returning value. Same happens with OZSafeERC20.safeTransferFrom and transferFrom. However, the use of transfer might render ETH...

Upgraded Q -> M from 44 [1655579898351]

Judge has assessed an item in Issue 44 as Medium risk. The relevant finding follows: 1. Usage of legacy ETH transfer function Risk Low Impact Contract ForgottenRunesWarriors for withdrawing ETH to vault uses send function, which has a fixed gas stipend and can fail. The reason behind this is that...

Eth may get stuck in contract

Handle JMukesh Vulnerability details Impact Istanbul hardfork increases the gas cost of the SLOAD operation and therefore breaks some existing smart contracts. In file withdrawable.sol, contract uses transfer to send eth from contract to EOA due which eth can get stuck. reason behind this is, aft...
