Congratulations to the person who managed to hack my contract! Next time, I won't go as easy. Stay tuned for the solution and future challenges! Meanwhile, you can check the exploit transaction here: etherscan.io/tx/0xdf6ba2bce38b479f36a97454c3919150586c5cd1e64effbc3e9f6ae0502e1353

[@XRLNetworks]

I'm hoping once I convert this back into eth server it ill work...

[@AdamanteBlockchainGuild]

Bom trabalho...Miguel, seria possivel criares um tutorial em como conseguir rastrear um hacker/scammer nas blockchains através do ip ou outro método que não seja apenas analisando as transacções no blockexplorer? Agradecido

[@dikejiakumiracle]

Can you make another video with easier method?

[@MAHMOUDIBRAHIM-nw7rq]

should i have to learn javascript

[@miguelvieiracode]

No. You can do the same with any language. If you like Python you can use web3.py for example, or you can simply do REST calls to any RPC node of the network

[@youtraders]

Im interested on channel

[@shutupji]
