Most of the hacks happened on the BSC and ETH networks. In third place in terms of attractiveness for hackers was the Arbitrum network. The openness of smart contracts on these networks makes it easy for hackers to find vulnerabilities. Reentrancy attacks and price manipulation attacks are still in the lead.

In case of rugpulls the situation is similar in terms of the distribution of the number of rugpull cases across different blockchains. The Ethereum network has experienced the most cases of theft of funds by the creators of DeFi protocols.

However, in terms of the amount of lost funds, the Optimism network is the undisputed leader. Despite the fact that we recorded only one case of rugpull in this network for the first four months of 2023 — Kokomo Finance, the amount of funds lost in this case is $4M, which is 42.64% of all funds lost due to rugpulls during this period.
