Let's talk about the Defi projects I've played and hacked. I won't talk about what I haven't played.,I've played too much and forgotten about it.,Write purely based on impressions.。 The following mines have all saved money but have withdrawn when they were hacked, and were lucky to escape: YFI Finance, the AC ace project, the ancestor of the machine gun pool, was hacked as well; YFV Finance, YFI's imitation disk, was stolen two or three times, and was hacked until it went out of business; Cream Finance, which was also hacked to the point of bankruptcy, was hacked by the revolving loan after the YFI Yusd calculation of the mortgage value was wrong; Sushi Finance, XSUSHI have profit loopholes, and there is no big problem. At that time, AAVE's xsushi also had the same value calculation problem as cream, but it couldn't be used. Curve Finance, the U I deposited, various ETH derivatives that were stolen, escaped; RDNT Finance, which was hacked to the point of bankruptcy; PackageBunny Finance, which was hacked to the point of bankruptcy; Qubit Finance, which was hacked to the point of bankruptcy; ankr, the ETH I deposited, it was BNB that was stolen, and I escaped; Alchemix Fi, which I was stolen long after I quit; abracadabra money, which I have stolen long after I withdrew; Blast, because the big Deth account was phished, and the various assets of the lending protocol in it were lent out by hackers to form bad debts. —— Lost part of the money of the mine: Harvest Finance: This is actually very hurt, I didn't save U but I held a lot of Farm at the time, although the TVL of 1 billion was only 30 million, but the Farm price was cut in half; Armor Fi, who was deceived by hackers into smashing the tokens of the project party, lost a little but was okay; Prisma Finance, where hackers take a small portion of the money in the pool. —— Lost but recovered mines: O3swap, this is a mine that has stolen a lot of money, Shenyu and many big investors are also there, fortunately they came back in the end, thanks to the help of many white hat companies; Kava Network, multichain for cross-chain bridges, I have stored it on the official website of Kava. Then the founder of multichain was arrested, and the deposit and withdrawal that had been open for a few days in the middle ran out, after which the door was closed forever. The U in FTM has also become waste paper; Defrost finance, the project team claimed to have lost 3 private keys at the same time and were hacked, I spent some money to find someone to locate the project party and contact them, so that the hacker turned to white hat. However, the largest deposit account has almost 10M USD, which is a bankrupt institution in the United States, and after they were taken over by a lawyer, the money has not been withdrawn, maybe the lawyer will not operate, and finally the money should be withdrawn by the project party; ParaSpace, the team that seems to be Shenyu preemptively executed the hacker's transaction and salvaged the money, thank you. —— The mine that really lost all the principal: Evodefi, a bridge, suddenly withdraws and then disappears; Cetus finance, the official Dex, has a strong background, and the accident is a bit unexpected. —— There may be some omissions in the stolen play, and there are various rule pits and rug pull mines, not to mention the hacker theft, so I won't write it. Anyway, after playing all the way, I feel that I have been stepping on the tightrope to make money, and the mines in the later stage have been selected more conservatively, and this time I really stepped on the thunder. After that, I should gradually reduce the investment in Defi, and make stock investments, so that I can sleep more peacefully.
