friend.tech is suspected of having a data breach and being able to buy and sell shares from the contract without an invitation code

Odaily Planet Daily News Spot on Chain tweeted that friend.tech has developed rapidly recently. For example, it only took 11 days to generate 2,953 ETH (about 5 million US dollars) in fee income. The total value of the current user share reaches 4435 ETH (approximately $7.4 million). However, the project also has some problems, including data leakage through the API, and the ability to buy and sell shares from the contract without an invitation code. From the perspective of the contract code, the invitation code and the application have no effect on the contract. Users can directly trade on Etherscan by linking MetaMask.
