Researchers from the National University of Singapore and University College London published a report reporting 34,200 problems in smart contracts Ethereum.
I noticed a problem
Experts downloaded Ethereum and checked about a million smart contract scenarios, revealing 34,200 vulnerabilities. After analyzing 3759 contracts, it was found that in 89% of cases there could be negative consequences. That is, attackers, having noticed this, would be able to steal about 6 million dollars.
The attempts of the team to calculate the creators of vulnerable smart contracts did not yield results. However, so far, the money will remain intact, because the researchers do not say which contracts have problems.
