# 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.
