In June 2021, according to incomplete statistics, there were more than 36 typical security incidents in the whole blockchain ecology. Defi is still in the primary position where security incidents occur frequently, and “flash loan attack” is still the primary attack method adopted by hackers. In addition, the security situation of fraudulent runway/crypto scams is serious nowadays and should not be taken lightly.
As the DeFi ecosystem has become more prosperous, various DeFi projects have been exposed to different security risks due to their different product designs and implementations. For example, in the xWin Finance hack, the attackers exploited the vulnerabilities in the project’s “promotion tools and rewards mechanism” to launch the attack; while in the SafeDollar hack, the attackers exploited the vulnerabilities in the project contract’s collateral and calculation. In the SafeDollar hack, the attackers exploited a flaw in the logic of the program’s contract on collateral and calculation of rewards.
The following are the details of this month’s monthly safety report.
On the exchange side, there were two typical security incidents:

Next, we will try to find a solution to the following problems in the insurance industry.
Contractors of insurance projects do not receive long-term stable insurance benefits.
Current insurance claims require an appraiser to make an assessment, and we would like to fully automate the claims process to eliminate human impact, but any current automated claims would narrow the insurance coverage.
We hope to add extra revenue to the insurance holder in some way.
