WHEN MY FIRST DECENTRALIZED WALLET WAS HACKED, I DID NOT KNOW WHAT TO DO
Friends, 5 years ago I stepped into the decentralized finance side for the first time. I opened a nice wallet and recorded 12 words in a notebook.
At that time, new ICOs and IDOs had started and I started to earn very good money by participating in them. I was entering every ICO and participating in every pre-sale that came my way, and I had no fear of my wallet being hacked because the 12 words were in my notebook and I was jumping into everything because they couldn't do anything to my wallet without them. (Of course, I didn't know what a smart contract is, what we sign when we sign, how revoke is done)
One day, as I continued to rapidly participate in pre-sales, a project called cryptoption, whose name I still remember, said that it would hold a rapid pre-sale and that it would be on its own website. I immediately researched the project, I liked it very much and I participated with a nice amount of BNB, unaware of what would happen. While we were waiting for the tokens to arrive the next day, the project's telegram channel was crashing. I knew what was going on before I even logged into my account. I immediately turned on the computer and looked at my account, all my BNB and USDT were withdrawn from my account. Because I had allowed all of their usage in the smart contract.
Without knowing what to do, of course, I wrote to Binance support and they told me to revoke, but of course it was gone. What I was happy about here was that nothing happened to the other coins in my wallet, many of my CAKE stakes were still where they were. My other coins were still there. After that day, I did a lot of research on how to ensure wallet security without participating in pre-sales for a long time and learned to read smart contracts. This was a big lesson for me.
