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 Drift exploit was carried out following a six-month social engineering campaign. Central to the new security measures is Stride, a structured evaluation program led by Asymmetric Research. Stride will assess Solana DeFi protocols against eight security pillars and publish its findings publicly.
Additionally, the Solana Incident Response Network (SIRN) has been introduced, a membership-based group of security firms and researchers focused on real-time crisis response. While these initiatives address part of the problem exposed by the Drift exploit, they do not directly address the mechanics that led to the loss.
The attackers spent six months building relationships with Drift contributors and compromised their devices through a malicious code repository and a fake TestFlight app, highlighting a human vulnerability rather than a compromise of smart contracts or code. Under Stride, protocols with more than $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.
The coverage will be calibrated to each protocol's risk profile. For larger 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. Founding members of SIRN include OtterSec, Neodyme, Squads, and ZeroShadow, with the network available to all Solana protocols but prioritized by TVL. The introduction of Stride's formal verification, however, would not have prevented the North Korean attack, which exploited 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 highlighted 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 to the attack. On-chain security expert ZachXBT criticized stablecoin issuer Circle Internet (CRCL) for failing to freeze over $230 million of its stolen dollar-pegged USDC during a six-hour window after the attack began.
A dedicated incident response network with established relationships to bridge operators, exchanges, and stablecoin issuers might have shortened the response time, although whether it would have been fast enough to prevent the Wormhole bridging and obfuscation through Tornado Cash remains uncertain. The foundation emphasized that the programs do not transfer the underlying responsibility away from the protocols themselves, a point that takes on a different significance after Drift's postmortem 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.
