ChainCatcher reported that Raydium, a Solana DeFi protocol, has confirmed an unauthorized liquidity removal attack against its legacy AMM V3 program pools. According to the official confirmation, the affected pools were part of an AMM V3 program that Raydium had deprecated in 2021.
The incident involved five pools: Sollet USDT-RAY, Sollet ETH-RAY, SRM-RAY, USDC-RAY and RAY-SOL. Raydium disclosed losses of about 150,000 RAY, 5,603 SOL and 893,700 USDC. Based on the figures provided, the total loss was approximately $1.34 million.
Raydium also stated that users are not currently affected. The attacker address has been marked, and the Raydium treasury will cover all compensation. Under the official handling plan described in the notice, the disclosed losses from the legacy pool incident will be borne by the Raydium treasury rather than by users.
