Why you should verify the tokens you own: Deep dive into hacked ERC20 contracts
cryptojobslist.comThis is case of substandard programming. Ethereum’s solidity tutorial has clear instructions for avoiding integer overflow and underflow bugs. Third party contract audit should be defacto standard for token roadmaps.
Hi HN,
This week trading on several tokens got halted due to discovered & exploited vulnerabilities in two smart contracts. One of them lost about 90% of its value… and another one lost 26% - $40,000,000 in market cap.
We wanted to focus more on the technical analysis of the situation to shed some light on common vulnerabilities that still abound.
Would love your feedback, since we got some mixed reviews on whether we did a correct technical judgment of one of the contracts. Especially of the SMT token.
it's pretty scary how many newbies to programming think they could charge money for consulting on Solidity projects. Which creates this massive bounty opportunity.
Especially for those with C/C++ experience, this must be a lot of fun
