# Solana Incident Response Network (SIRN) **Type:** Security coordination infrastructure **Status:** Active **Launch Date:** April 7, 2026 **Parent Organization:** Solana Foundation ## Overview Solana Incident Response Network (SIRN) is network-wide security coordination infrastructure launched by the Solana Foundation in direct response to the April 1, 2026 Drift Protocol exploit ($285M). ## Mission - Improve incident response speed across Solana protocols - Coordinate security responses ecosystem-wide - Provide infrastructure for cross-protocol security collaboration ## Timeline - **2026-04-01** — Drift Protocol exploit ($285M) via durable nonce vulnerability - **2026-04-07** — SIRN launched by Solana Foundation (6-day response time) ## Scope and Limitations SIRN focuses on incident response coordination, not protocol-level fixes. As of launch, it does NOT address: - The durable nonce vulnerability (indefinite transaction validity) - Zero-timelock governance migration patterns - Device compromise prevention (TestFlight/IDE vulnerabilities) The distinction between coordination infrastructure and architectural fixes is significant for assessing whether the Drift exploit represents a persistent Solana governance risk or a fixable design pattern. ## Sources - CoinDesk: https://www.coindesk.com/tech/2026/04/07/solana-foundation-unveils-security-overhaul-days-after-usd270-million-drift-exploit
