The Solana Foundation has announced a comprehensive set of security initiatives, coming just days after the decentralized finance platform Drift Protocol suffered a significant $270 million exploit at the hands of a North Korean state-affiliated group. This attack was the result of a six-month social engineering campaign. At the forefront of these initiatives is Stride, a rigorous evaluation program led by Asymmetric Research. Stride will assess Solana DeFi protocols against eight key security pillars and publicly disclose its findings.
Additionally, the Solana Foundation has introduced the Solana Incident Response Network (SIRN), a membership-based group comprising security firms and researchers focused on providing real-time crisis response. While these initiatives address some of the vulnerabilities exposed by the Drift exploit, they do not directly tackle the root causes of the loss. Notably, Drift's smart contracts were not compromised, and their code had passed audits. The actual vulnerability was human in nature: the attackers spent six months establishing relationships with Drift contributors and compromised their devices through a malicious code repository and a fake TestFlight app.
Under the Stride program, protocols with more than $10 million in total value locked (TVL) that pass the evaluation will be eligible for ongoing operational security and active threat monitoring, funded by Solana Foundation grants. The level of coverage will be calibrated to each protocol's specific 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 ensure correctness. In addition to Asymmetric Research, the founding members of SIRN include OtterSec, Neodyme, Squads, and ZeroShadow.
While the network is available to all Solana protocols, priority will be given based on TVL. Stride's formal verification, however, would not have prevented the North Korean attack, which utilized 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 detected 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.
However, SIRN could have potentially aided in the response efforts. ZachXBT, an on-chain security expert, criticized stablecoin issuer Circle Internet (CRCL) for failing to freeze over $230 million of its stolen dollar-pegged USDC during the six-hour window following the attack. A dedicated incident response network with established relationships to bridge operators, exchanges, and stablecoin issuers might have shortened the response time.
Whether it would have been fast enough to prevent the Wormhole bridging and obfuscation through Tornado Cash remains an open question. The foundation emphasized that these programs 'do not transfer the underlying responsibility away from the protocols themselves,' a statement that takes on a different meaning in the aftermath of Drift's 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.
