Yudistira Putra

Smart Contract Security Researcher | EVM · SVM · MoveVM

Core Competency

I specialize in manual, opcode-level analysis and deterministic exploit development. My focus is on breaking protocol invariants and identifying deep-seated architectural flaws where automated tooling fails.

EVM (Ethereum)

  • State transition dynamics
  • Yul/Opcode optimization
  • Proxy bypass (UUPS/Diamond)
  • Cross-contract state manipulation

SVM (Solana)

  • Account model validation
  • PDA derivation security
  • CPI instruction order flaws
  • Rust-based Anchor auditing

MoveVM (Sui/Aptos)

  • Resource safety invariants
  • Integer truncation math
  • Type-reflection exploits
  • Liquidity math overflows

The Lab: Offensive Research

  • DeFi-Exploit-PoCs: Re-engineering high-severity exploits (Euler, Illuminate, etc.) with hard-assertion regression tests.
  • applied-audit-findings: Technical post-mortems of complex logic errors and invariant failures from private/public audits.

Technical Stack

Languages: Solidity, Yul, Rust (Anchor), Move, Python, Bash.
Frameworks: Foundry, Hardhat, Solana CLI, Sui CLI, Aptos CLI.
Security Tools: Echidna, Halmos (FV), Medusa, Slither, Trident.
