Did Arbitrum Violate DRPK's Property Rights? No, Because It Wasn't Their Property

Key Takeaways

• Attack used RPC/Geth compromise and spoofed transactions to mint rSETH, borrow on Aave, and drain ~ $300M—this wasn’t simple key theft, so assume advanced multi‑vector attacks.
• Treat bridges as critical infrastructure: require audits, safer defaults, robust monitoring, and stricter multisig/multi‑operator configurations to reduce cross‑chain contagion from high‑LTV looping.
• Response involved rapid multisig bridge upgrades and freezes to save ~$70M; signatory counts and narratives are contested—document decision processes and legal/ethical guardrails in advance.
• Sequencer limits: a single sequencer can censor but cannot cryptographically move funds; design escape hatches, fraud proofs, and L1 fallbacks to preserve user recourse.
• Operational playbook: run red‑alert drills, pause affected bridges immediately, avoid broadcasting architecture details, and favor security‑first roadmaps over feature velocity.
• Regulatory and market fallout: expect increased scrutiny, shifting custody behavior, lower risk appetite for exotic yields, and pressure on L2s to adopt compliance measures.
