Marwan Maro

Smart Contract Security Researcher focused on DeFi protocol security, competitive audits, and security tooling.

Code4rena Cantina LinkedIn GitHub

I review smart contracts, study DeFi failure modes, and build Rust/TypeScript tools around EVM security workflows. My current focus is turning audit experience into practical monitoring, analysis, and reporting tools.

Security Highlights

  • Valid high and medium severity findings on Code4rena.
  • Helped secure Olas and Rujira through competitive smart contract audits.
  • Code4rena signal: Good.
  • Active on Code4rena and Cantina.
  • Merged Rust contribution to Warp terminal.
  • Contributor to smart contract security tooling, including Cyfrin Aderyn.

Featured Work

EVM Security Monitor

Rust-based MVP for a blockchain security monitoring backend.

  • Built with Rust, Axum, Tokio, SQLx, and SQLite.
  • Includes CLI commands for watched contracts, alert rules, and demo alerts.
  • Exposes REST and WebSocket APIs for health checks, contracts, rules, and alerts.
  • Includes Docker, docker-compose, GitHub Actions CI, and a clean deployment path.
  • Designed around extensible rules for large transfers, admin changes, suspicious approvals, and pause events.

Repository: evm-security-monitor

NullTrace

Dev3Pack hackathon project for AI-powered DeFi security intelligence, exploit monitoring, transaction analysis, and forensic incident reports.

  • Next.js, TypeScript, Tailwind CSS.
  • AI-assisted contract and transaction analysis.
  • DeFi incident feed and forensic dossiers.
  • LI.FI emergency bridge flow and x402 payment gate.

Repository: nulltrace-ai
Live: nulltrace-eight.vercel.app

Competitive Audits

Public competitive audit profiles with validated DeFi findings.

  • Code4rena: 1 high severity finding, 1 medium severity finding.
  • Helped secure: Olas, Rujira.
  • Cantina profile for ongoing vulnerability research.
  • Writeup: Olas broken TWAP validation

Open Source Contributions

Practical contributions to developer tools and security tooling.

  • Warp terminal: merged Rust contribution improving Markdown file-link behavior so it respects the user's Markdown Viewer preference, with regression test coverage and wasm CI follow-up.
  • Cyfrin Aderyn: contributed to the costly loop detector by reducing false positives from for-loop initializers and updating report baselines.
  • Foundry: opened a Chisel regression fix around dynamic bytes/string ABI memory display.

Technical Focus

  • Smart contract security and DeFi vulnerability research.
  • Solidity, EVM internals, fuzzing, and invariant testing.
  • Rust backend development and systems-level debugging.
  • Security monitoring, static analysis, and audit workflow tooling.
  • TypeScript applications for security dashboards and research interfaces.

Current Priorities

  • Publishing sanitized audit writeups from competitive findings.
  • Building a public audit portfolio with reproducible vulnerability notes.
  • Improving Rust and TypeScript tooling for EVM security workflows.
  • Contributing to high-quality open-source security and developer tools.
