Smart Contract Engineer · Protocol Architect
I'm Dorian Voss — an 8-year veteran of decentralized systems. I design, build, and audit smart contracts that have secured over $2.1B in on-chain value for 40+ protocols across Ethereum and Solana.
01 — About Me
Berlin, Germany · Available Q3 2025
I entered this field in 2017, a year after the DAO attack, driven by one conviction: the promise of decentralization is worthless if the code isn't bulletproof. Since then, I've built lending protocols from scratch, led audits on some of the most complex derivative exchanges in DeFi, and contributed to open-source security tooling adopted by 200+ projects.
My approach is conservative by design — I write code that survives. I obsess over invariants, edge cases, and the economics that make a system attack-resistant. When I'm not in the code, I'm mentoring at Ethereum Foundation hackathons or writing on the dark corners of formal verification.

A
ALPHA LEDGER
2024 · DeFi Lending · ETH
An isolated lending market that lets DAOs borrow against governance tokens without liquidation cascades. Architected the core lending engine and proposed a novel redemption mechanism that reduces bad-debt exposure by 73% compared to standard Aave-style models.
S
SOLSTICE EXCHANGE
2023 · Derivatives · Solana
A fully on-chain options exchange that settled $340M in volume in its first year. Led the move from outdated smart contracts to a more efficient solana program architecture, slashing user gas costs by 4x while maintaining sub-second settlement latency.
V
VAULTKIND
2022 · Security Tooling · MIT
An open-source library of battle-tested, audited invariants for ERC-20 vaults. It's now used by over 200 projects to run property-based tests on their yield strategies, uncovering edge cases that standard auditing tools miss.

“Dorian led the redesign of our core vault contracts. The audit came back clean after his first pass — that's never happened before at Halden Labs. He's the only engineer I trust with user funds.”
— Elena Petrova, Head of Protocol, Halden Labs

I'm currently available for select protocol design, security audits, and as a technical advisor for early-stage teams. If you're building something where the integrity of the code is the business, let's talk.
