Hi, I'm Emin Karagoz — a Web3 developer focused on cross-chain infrastructure, economic security systems, privacy-first design, and agent-driven on-chain applications.
Focused on building systems that operate under adversarial and uncertain conditions.
This is a curated collection of my most meaningful work — spanning hackathons, infrastructure experiments, and research-oriented systems.
OverSync moves native assets between Ethereum and Stellar atomically. Funds are locked in hash-time-lock contracts on both chains; settlement is a sha256 preimage reveal, not a multisig attestation. If anything in the bridge fails — coordinator down, resolver malicious, RPC rate-limited, frontend offline — the locked funds either settle to the beneficiary or refund permissionlessly to the user. There is no state in which user funds are stranded under operator control.
