Hi, I'm Emin Karagöz — a Web3 developer building privacy-preserving protocols, autonomous agent infrastructure, cross-chain systems, and programmable financial applications.

My work focuses on Stellar/Soroban, confidential coordination, AI agent payments, RWA infrastructure, cross-chain execution, and verifiable autonomous systems.

A confidential coordination primitive for Stellar that enables sealed voting, auctions, grant scoring, procurement, and allocation rounds.

Participants commit encrypted decisions to a Soroban contract and lock escrow before a future Drand round. Once the reveal round arrives, commitments are opened simultaneously through publicly verifiable timelock cryptography, removing operators from the trust path.

Built as reusable infrastructure for Stellar applications, including a Soroban round contract, TypeScript SDK, timelock encryption toolkit, permissionless keeper, and integration templates.

🌐 Live App

Confidential bookbuilding infrastructure for tokenized real-world assets on Stellar.

QuietBook lets issuers collect investor bids without exposing bid prices, sizes, or balances during price discovery while keeping final allocation and settlement verifiable on-chain.

OverSync moves native assets between Ethereum and Stellar atomically.

Funds are locked in hash-time-lock contracts on both chains, with settlement triggered by a SHA-256 preimage reveal rather than multisig attestations.

If coordinators, resolvers, RPC infrastructure, or the frontend fail, funds either settle correctly or become permissionlessly refundable.

Autonomous spending infrastructure that allows AI agents to transact on Stellar under enforceable wallet policies.

AgentAllowance combines delegated authorization, spending limits, recipient policies, and x402 payment flows so agents can pay for services without receiving unrestricted treasury access.

🛠 Tech: Stellar, Soroban, x402, Smart Accounts, TypeScript, OpenZeppelin

A marketplace where AI services are discovered, called, and paid for autonomously.

Each tool invocation is paid through GOAT Flow / x402, while backend payment verification ensures services are fulfilled only after settlement confirmation.

🛠 Tech: GOAT Network, GOAT Flow, x402, TypeScript, AI Agents

A confidential credit coordination network where issuer, investor, underwriter, auditor, and settlement agents coordinate private RWA funding rounds.

Kavro combines sealed commitments, AI underwriting, permissioned disclosure, and on-chain repayment settlement while separating public verifiability from sensitive credit intelligence.

🛠 Tech: Next.js, Solidity, TypeScript, 0G Storage, 0G Compute, 0G Chain

🌐 Live App

A confidential campaign layer for token operations built on Zama FHE.

CloakOps enables contributor rewards, advisor vesting, and community distributions where allocations and metadata remain encrypted on-chain while campaign rules stay publicly verifiable.

🛠 Tech: Solidity, TypeScript, Next.js, Zama FHE, TokenOps

🌐 Live App

A privacy-preserving proof-of-reserves system for Stellar.

Solvent allows institutions to demonstrate asset backing without publicly exposing sensitive treasury structure or account-level information.

🛠 Tech: Stellar, Zero-Knowledge Proofs, TypeScript

A terminal-first builder for 0G workflows with prompt-driven generation, local preview, and deployment pipelines.

🛠 Tech: TypeScript, Node.js, CLI

🌐 Demo · 📦 npm

An autonomous service buyer designed to recover when agent services fail.

ReSource evaluates providers, executes purchases, verifies outcomes, and searches for alternative execution paths when a service becomes unavailable or returns an unusable result.

🛠 Tech: TypeScript, AI Agents, Autonomous Commerce, Keeper Infrastructure

An event-aware autonomous market agent built to react to live football market shocks and dynamically manage exposure.

🛠 Tech: Python, AI Agents, Market Automation

An agent-consumable service provider built for the OKX.AI ecosystem.

Paid calls settle in USDT0 on X Layer through x402 v2 and the OKX Payments SDK, allowing autonomous agents to purchase services programmatically.

🛠 Tech: Python, OKX.AI, X Layer, x402, USDT0, AI Agents

A recurring-demand and request-for-quote engine for autonomous agents.

Designed for agent economies where buyers continuously generate demand and providers compete to satisfy requests programmatically.

🛠 Tech: Python, AI Agents, RFQ Markets, Autonomous Commerce

Assay evaluates which creator information sources are worth purchasing and pays them per use through x402.

The system turns data evaluation and purchasing into a machine-native workflow.

🛠 Tech: TypeScript, x402, Arc, AI Agents

A payment firewall for MetaMask Smart Accounts that constrains autonomous agents to narrowly scoped permissions.

Each payment is bound to the exact request that authorized it, allowing child agents to operate without receiving unrestricted wallet authority.

🛠 Tech: TypeScript, MetaMask Smart Accounts, x402, Agent Permissions

Pre-funded stablecoin vouchers that can be accepted over a local peer-to-peer mesh while offline and settled on-chain once connectivity returns.

🛠 Tech: TypeScript, Stablecoin Payments, P2P Networking
