Alireza Arjmand

I am a decentralization enthusiast, focused on exploring, breaking, and learning about various blockchain systems. I like to understand and hack complex DeFi systems, cross-chain protocols, and Layer 2 solutions, learning them bottom up and breaking them top down.

I believe in learning by doing, and audits have been the perfect opportunity for that. I’ve been fortunate to work with amazing teams throughout my career. Currently I’m an LSR at Spearbit, before that I worked as an auditor at OpenZeppelin.

Auditing Experience

OpenZeppelin (2.5 years)

During my time at OpenZeppelin, I contributed across critical DeFi infrastructure. I completed 50+ audits and reviews for projects such as Compound, Uniswap, Sandbox, Origin, Scroll, and Linea.

I had a special focus on Compound during my time at OpenZeppelin. You can find some of my contributions below:

• Leadership in Compound reviews:

  • Audited the base protocol and uncovered multiple edge cases and issues.
  • Helped in the incident responses during high-pressure situations.
  • Reviewed governance upgrades (such as Governor upgrade, Market Admin, Comet Wrapper grant) and other Compound-related grants.

• Tooling and automation: Designed and implemented internal automation and tooling to help audits and reviews.

• Governance review: Performed 90+ proposal reviews, migrations and token assessments.
