Kame Aggregator
Summary
Kame Aggregator is a decentralized exchange (DEX) aggregator protocol built on the Sei blockchain, launched in late May 2025, designed to route token swaps across multiple liquidity sources for optimal pricing. On September 13, 2025, the protocol suffered a critical smart contract exploit in which approximately $1.325 million was drained from 830 user wallets via an arbitrary external call vulnerability in its swap() function. The primary exploiter returned approximately $946,000 after negotiations, while secondary exploiters retained approximately $357,000; the team initiated a compensation program that reached over $1 million USDC in distributions by November 2025.
