🐊 The joy of discovering Web3 vulnerabilities Nobel laureate in physics, Feynman, once said: He doesn't really care about winning the Nobel Prize because in the process, he has already received a reward, which is: The joy of discovery. In the cryptocurrency/Web3 community, discovering vulnerabilities is not just fun, but often comes with additional benefits. So the fun basically doubles. For example, the technique shared by this old man Top1 to boost funding costs for second tier CEX is truly exceptional. A few seconds before the settlement of the fund fee, open a position with ultra-high leverage (following the direction given to you by the settlement fund fee). On the premise of maximizing the utilization rate of principal, even if the principal is subsequently liquidated, the capital cost still far exceeds the loss of principal. Exquisite. The first one to discover and exploit this' loophole ', calling them a genius would be an exaggeration. To be precise, this is very different from hackers exploiting vulnerabilities to steal funds. At best, it can be considered as discovering the "unreasonable" aspects of the system rules and openly exploiting them. Although it has developed for over a decade, the entire cryptocurrency community/Web3 is still in a relatively primitive early stage, so if you are more careful, you will always find some strange and peculiar rule gaps. For example, I also have an interesting case here. About 2 years ago, at that time, it was probably the end of the bear and the beginning of the bull, and the OP of L2 was still at its peak. At that time, OP was still collaborating with major project teams to organize Odyssey events, with each event featuring a TV that looked like a small one 📺 The NFT. At that time, Stargate's activity, which had not yet released coins, required you to cross chain between the chains he supported for more than $100. Users who met the requirements could receive the official small TV NFT, and Stargate also provided an additional first NFT called: Stargator。 Due to the high ease and popularity of Layer Zero at the bottom of Stargate, this official Stargate NFT is believed to have weight bonuses when Layer Zero is released in the future. Therefore, it has a price and transaction on the secondary market (Opensea) as soon as it is released. In addition, there are also many conditions for wanting Mint as an NFT. The official requirement is that you need to hold a Stargate small TV and cross the chain before you can mint. Moreover, the official Mint NFT smart contract is not open source. In short, it is valuable and difficult. But later, by a twist of fate, I discovered a fast and almost zero cost Mint method.
