Nirlin β€” Independent Protocol Security Researcher

Rust & Solana protocol security.
70+ systems reviewed Β· 100+ critical vulnerabilities found Β· Architecture reviews & audit reports


Finding critical bugs before attackers do.


About

I am an independent protocol security researcher focused on Rust, Solana, SVM, EVM, and Move security.

I help teams secure high-risk protocol logic through deep audits, architecture reviews, exploit-path analysis, and private security reporting.

So far, I have reviewed 70+ protocols and systems and found 100+ critical vulnerabilities across private audits, competitive security research, and production protocol reviews.

My primary focus is Rust and Solana protocol security, including Anchor programs, SVM-specific attack surfaces, account validation, CPI safety, economic logic, and production protocol architecture.


Work With Me

I am available for select security engagements involving:

  • Solana / Rust audits
  • Anchor smart contract reviews
  • SVM protocol security
  • Protocol architecture reviews
  • EVM smart contract audits
  • Move protocol reviews
  • Bridge and cross-chain system reviews
  • Critical bug analysis
  • Private audit reports

For public examples of my work, see:

Some engagements, reports, and vulnerability details are private due to client confidentiality.


Contractor Work & Collaborations

I work as an independent contractor with leading security teams and audit groups, including:

  • Adevar Labs
  • Cyfrin
  • Pashov Audit Group

This includes private audits, protocol reviews, competitive security research, and production system assessments across Solana, EVM, Move, Berachain, L1s, bridges, and other on-chain systems.


Security Track Record

100+ Critical Vulnerabilities Found

I have identified critical vulnerabilities across production code, private audits, and competitive security reviews, including issues involving:

  • Loss of funds
  • Broken access control
  • Incorrect account validation
  • Faulty protocol accounting
  • Unsafe CPI flows
  • Economic logic flaws
  • Liquidation and collateral bugs
  • Bridge and cross-chain risk
  • Incorrect state transitions
  • Privilege escalation paths

70+ Systems Reviewed

My review experience spans:

  • Solana protocols
  • Rust / Anchor programs
  • EVM smart contracts
  • Move protocols on Aptos and Sui
  • Berachain applications
  • L1 systems
  • Bridges and cross-chain infrastructure
  • DeFi protocols
  • Prediction markets
  • Infrastructure and middleware systems

Core Focus Areas

Solana / Rust / SVM

My strongest area is Solana protocol security, especially:

  • Anchor program audits
  • PDA and seed validation
  • Account ownership and signer checks
  • CPI safety
  • Token account validation
  • Rent, lamports, and account lifecycle issues
  • Integer precision and accounting bugs
  • State machine vulnerabilities
  • Permission and authority design
  • Protocol-level exploit paths

EVM

I also review EVM systems involving:

  • DeFi protocol logic
  • Access control
  • Accounting and share math
  • Liquidations
  • Oracle assumptions
  • Upgradeability risks
  • Governance and permissioning
  • Cross-contract interactions

Move

I have reviewed Move-based systems across:

  • Aptos
  • Sui
  • DeFi protocols
  • Resource and capability-based logic
  • State transition safety

Public Audit Reports

A selection of public audit reports is maintained here:

The portfolio includes public reports across multiple ecosystems and protocol types.


Audit Competition Results

Selected competitive audit placements:

  • πŸ₯ˆ 2nd β€” KelpDAO, Code4rena
  • πŸ₯ˆ 2nd β€” Aloe V2, Sherlock
  • πŸ₯‰ 3rd β€” Hubble Exchange, Sherlock
  • 4th β€” Unstoppable, Sherlock
  • 4th β€” Ondo Finance, Code4rena
  • 6th β€” Axelar, Code4rena

Development Work

PNP β€” Solana Migration

Helped migrate PNP, a prediction market protocol, to Solana by rewriting its smart contracts in Anchor.

The migrated contracts have been in production for 8+ months.

This development experience helps me audit Solana systems from both an attacker and builder perspective.


Research

I occasionally publish Solana and protocol security research here:

Research topics include:

  • Solana security
  • Rust smart contract bugs
  • SVM internals
  • Protocol architecture
  • Exploit analysis
  • Audit methodology
