Raydium Confirms $1.34M Hack on Legacy AMM V3, Pledges Full User Compensation

Solana-based decentralized finance protocol Raydium (RAY) has confirmed a security breach that resulted in the loss of approximately $1.34 million. In an official statement released via X, the team disclosed that the attack targeted an old legacy AMM V3 program, exploiting a vulnerability in the liquidity token issuance validation process.

How the Exploit Occurred

According to Raydium’s post-mortem, the attacker managed to bypass liquidity ratio checks within the legacy program, allowing unauthorized withdrawals of funds. The protocol was quick to clarify that its current mainnet program, software development kit (SDK), and decentralized application (dApp) remain unaffected. The vulnerability was isolated to the older infrastructure that had been phased out for newer iterations.

Compensation and Security Response

Raydium has assured users that all losses will be fully compensated. The team is currently conducting additional security audits across all mainnet programs to prevent future incidents. This proactive measure aims to restore user confidence and strengthen the protocol’s overall security posture.

Broader Implications for DeFi Security

This incident highlights a recurring challenge in the DeFi space: legacy codebases that remain operational after protocol upgrades. While Raydium’s swift response and compensation pledge are positive steps, the hack underscores the importance of continuous auditing and the retirement of outdated smart contracts. For users, it serves as a reminder to monitor protocol announcements and migrate to updated versions when available.

Conclusion

Raydium’s handling of the $1.34 million hack—transparent disclosure, unaffected core systems, and a commitment to full reimbursement—reflects a maturing approach to crisis management in DeFi. However, the event reinforces the need for rigorous security practices across all layers of a protocol, especially legacy components that may still hold user funds.
