Kinto was a KYC-enforced Ethereum Layer 2 built on the Arbitrum Nitro stack, marketing itself as a 'safety-first' DeFi protocol with built-in AML and identity verification. On July 10, 2025, an attacker exploited a CPIMP proxy vulnerability in the $K token contract on Arbitrum, minting 110,000 unauthorized tokens and draining approximately $1.55–1.9 million from Uniswap V4 and Morpho Blue liquidity pools. Despite a partial recovery effort dubbed 'Phoenix,' the project announced shutdown effective September 30, 2025, as fundraising options collapsed and the team ran unpaid for months.
