Milos Mirkovic

Solidity / Smart Contract Engineer ⚙️
Focused on protocol engineering: EVM internals → security → DeFi systems

Current Focus

Building a DeFi lending protocol from first principles:

  • oracle systems (Chainlink + custom RWA oracle)
  • AMM price formation and TWAP
  • lending pools and liquidation mechanics
  • utilization-based interest rate models
  • staking and reward distribution

Main repo:
https://github.com/MilosMicun/defi-lending-primitives

Protocol Engineering Approach

Each repository represents a core system component:

EVM Fundamentals

Understanding execution at opcode, memory, and storage level.

Testing & Verification

Unit, integration, fuzz, and invariant testing using Foundry.

Security

Exploring vulnerabilities and defenses:

  • reentrancy
  • access control
  • overflow
  • MEV / front-running

Oracle Design

Safe integration of external data:

  • staleness checks
  • deviation limits
  • round validation
  • stateful price model

Key Idea

Smart contracts are not just code.

They are:

  • state machines
  • accounting systems
  • adversarial environments

Correctness emerges from:

math + state + time
