Incident Details

Although Coinbase’s Base blockchain is at this stage intended for testing only, people have begun bridging substantial assets to the platform and using various services in anticipation of its official launch.One such service is LeetSwap, which describes itself as the “The #1 DEX ecosystem for elite degens built on the leetest blockchains”, and which recently launched its service on Base. On August 1, LeetSwap was exploited after an attacker discovered a function that allowed them to manipulate token prices on the project for a profit of around 342 ETH ($624,000).LeetSwap attempted to contact the hacker via social media, asking them to return all but 50 ETH ($92,000, or around 15% of the stolen funds).

Total loss estimated at $624,000.
