Timur Güvenkaya

Principal-led security reviews for stablecoins, custody, and onchain finance.

Guvenkaya secures digital assets and financial infrastructure: stablecoins, smart contracts, custody, cryptography, and the applications and cloud systems around them.

Our team brings experience from Kraken, OpenZeppelin, Binance, ZKsync, Nillion, Union Labs, Composable Finance, Tectonic Labs, Invicti, and EY alongside the sitting Heads of Security at Gauntlet and Agora; one specialist's prior work includes individual assessments for Coinbase, Jupiter, Kyber, and MegaETH.

Across the team: $30B+ in volume secured and 200+ security reviews.

What we do differently:

  • Every reviewer has a public bio and is named before you sign. A principal leads scoping and threat modeling and checks every finding.
  • Alongside findings, you get a threat model, invariant register, new tests in your repo, and a record of every tested attack scenario.
