and what is the chance of having them hiring him or others very competent guys of that kind to increase their security team ?

Would you employ a thief?

this "thief" is a man more clever and with a better understanding of the Elrond code than the whole Elrond dev team... he found something that none of them have seen, lets say he is a "clever thief". And by the way This question leads me to a more general one. Has the dex had a security audit? by an independent auditor? Has the Elrond team ever conducted any bug bounty program with significant awards?

Okay let’s wait to see if they employ him????
