Just five days after the decentralized finance platform Drift Protocol suffered a $270 million exploit at the hands of a North Korean state-affiliated group, the Solana Foundation has announced a suite of security initiatives. The cornerstone of this effort is Stride, a structured evaluation program led by Asymmetric Research, which will assess Solana DeFi protocols against eight security pillars and publicly disclose its findings.
Additionally, the foundation has introduced the Solana Incident Response Network (SIRN), a membership-based group of security firms and researchers focused on providing real-time crisis response. While these initiatives address some of the issues exposed by the Drift hack, they do not directly address the human vulnerability that was exploited.
The attackers had spent six months building relationships with Drift contributors and compromised their devices through a malicious code repository and a fake TestFlight app. Under Stride, protocols with over $10 million in total value locked (TVL) that pass the evaluation will receive ongoing operational security and active threat monitoring, funded by Solana Foundation grants, with coverage tailored to each protocol's risk profile. For protocols with over $100 million in TVL, the foundation will also fund formal verification, a mathematical method that checks every possible execution path in a smart contract to guarantee correctness.
The network includes founding members such as OtterSec, Neodyme, Squads, and ZeroShadow, and is available to all Solana protocols, prioritized by TVL. However, it is noted that Stride's formal verification would not have prevented the North Korean attack, which used compromised devices to obtain multisig approvals that were then locked into durable nonce transactions and executed weeks later. Similarly, 24/7 monitoring of on-chain activity would not have caught the attack, as the transactions were valid by design and indistinguishable from legitimate administrative actions until they were used to drain the vaults. The attack exploited the gap between on-chain correctness and off-chain human trust, a gap that no smart contract audit or monitoring tool is designed to cover.
On the other hand, SIRN could have potentially aided in the response to the attack. The foundation has emphasized that these programs do not transfer the underlying responsibility away from the protocols themselves, a point that takes on a different meaning in light of the Drift postmortem, which revealed that individual contributor devices were the entry point for a nation-state attack. Solana already offers several free security tools for builders, including Hypernative for threat detection, Range Security for real-time monitoring, and Neodyme's Riverguard for attack simulation.
