Raydium Suffers $1.34 Million Exploit on Deprecated AMM V3 Liquidity Pools

Jun 9, 2026

Solana-based exchange Raydium suffered a $1.34 million exploit targeting five deprecated AMM V3 liquidity pools from 2021. The attacker exploited a logic flaw, creating a fake LP mint to bypass validation and drain assets. No current users were affected as the pools were inaccessible via the official UI. Raydium has committed to compensating all losses from its treasury and is conducting a full security review.
