Our Team
HasFocus is built by a small, focused team of security researchers and engineers. We believe in depth over breadth -- every team member is a hands-on auditor.
Who we are
Our founding team brings backgrounds in smart contract security, applied cryptography, and protocol engineering. We have experience across the EVM ecosystem (Ethereum, Arbitrum, Optimism, Polygon, Base) as well as Solana and CosmWasm.
We are intentionally small. Every audit is conducted by senior researchers -- we do not hand off work to juniors or outsource to subcontractors. When you work with HasFocus, you work directly with the people reviewing your code.
Areas of Expertise
Smart Contract Auditing
Deep expertise in Solidity, Vyper, and Move. Manual line-by-line review combined with custom static analysis tooling.
DeFi Protocol Design
Hands-on experience with AMMs, lending protocols, bridges, governance systems, and stablecoin mechanics.
Formal Verification
Property specification and verification using Certora, Halmos, and HEVM for mathematical security guarantees.
EVM Internals
Low-level understanding of the EVM, storage layout, gas optimisation, and proxy upgrade patterns.
