On-chain betting & prediction markets · Pre-audit code reviews

Architect of the smart contract core of Azuro Protocol — a live on-chain betting & prediction markets layer: $400M+ cumulative volume, $5.2M+ protocol revenue, 41,000+ users, and 51 third-party apps built on contracts I designed, deployed across Polygon, Gnosis, Base, and Arbitrum.

A focused security review by a senior engineer who has shipped production smart contracts handling real money. Designed to be done before you pay for a full audit, so you don't waste $20K+ on a remediation round catching obvious issues.

Scope: up to 1500 nSLOC · Solidity / EVM only

Deliverable: PDF report with findings classified by severity (Critical / High / Medium / Low / Informational + Gas optimizations), reproduction notes, and suggested fixes. Includes one 30-minute call to walk through the report.

What I look for: input validation, access control, oracle and price-feed assumptions, rounding and precision in liquidity math, reentrancy and external-call patterns, accounting consistency in dynamic LP pools, role and permission design, common patterns behind recent exploits.

Particular depth: betting / prediction markets mechanics, dynamic LP pool accounting, and liquidity math — the places where rounding and accounting bugs like to hide. I've designed and defended this exact class of contracts through multiple external audit rounds.

Not included: formal verification, economic / game-theoretic modeling, off-chain or infrastructure security. Re-review after fixes available separately ($1K).

A pre-audit review is not a substitute for a full security audit by a specialized firm. The protocol team retains full responsibility for the security of deployed contracts.

Design and delivery of production smart contract systems, end to end: architecture → implementation → testing (Foundry / Hardhat) → audit preparation and remediation → mainnet → maintenance.

Strongest fit: prediction markets, on-chain betting / iGaming mechanics (market & odds lifecycle, LP-backed pools, payouts, risk controls), and DeFi liquidity systems.
