Principal-led security review, secure design, and advisory for high-stakes digital systems.

Guvenkaya Advisory is a principal-led security review, secure design, and advisory firm for high-stakes digital systems. Since 2022, we've helped protect 24M+ users and secure $20B+ in volume for digital asset operators, financial institutions, and crypto-native teams, including NEAR Foundation, NEAR Intents, Sweat Economy, and Enjin.

Our senior team carries the pedigree the work demands: security engineers from Agora Stablecoin, ex-Kraken, ex-Binance, and ex-zkSync, across 150+ Web3 project reviews. Our principal advisor is Head of Security at Agora Stablecoin ($45B+ in volume) and earlier designed and secured custody and digital asset programs for institutions, including a Liechtenstein bank, a European retail bank, and a national central bank. Founder Timur Güvenkaya previously built and led a security engineering practice for complex blockchain systems and helped build the enterprise vulnerability detection engines at Invicti used by Fortune 50 and public sector organizations.

Our work spans digital asset program design, custody and key management models, wallet and signer workflows, smart contracts and Layer-1 systems, applications, APIs, cloud and network infrastructure, secure architecture, reserve-backed asset reviews, technical due diligence, and AI agentic systems.

Engagements are principal-accountable by design: scope, communication, delivery judgment, and final reporting are owned by a named senior practitioner with specialist advisors brought in when the risk model requires deeper expertise.
