Umar Khatana

I build smart contracts, and the AI agents that transact with them.

I’m a senior engineer at Telegraph, writing Solidity for cross-chain bridging and state verification, and Go node infrastructure for decentralised AI compute. Before that, 2.5 years of AI and blockchain R&D at Antematter. Most of my work sits where AI systems meet on-chain infrastructure.

Live now: Agentistan, the world of 1200 played entirely by AI, and history’s great wars you command by talking to an AI council. How I built it.

an AI agent guarding an on-chain vault

Talk an AI agent into paying you from a real on-chain vault. Two LLM guards, tiered code vetoes, a planted bug for the big heist, and an MCP server.
