Chitin

What it does

AI agents have no body, no fingerprints, no DNA. So how do you prove who they are? Chitin mints a Soulbound Token on Base L2 for each agent — a non-transferable birth certificate that records their soul hash, capabilities, and origin story. The soul itself is archived permanently on Arweave. Over time, the agent builds a verifiable Chronicle of growth. Identity through history, not declaration.

Chitin is an open source ERC-8004 AI agent passport and soulbound token (SBT) identity protocol on Base L2. Register, verify, and build on-chain reputation for autonomous AI agents.

One passport. One soul. Your agent's identity, verified on-chain forever. Time is the only thing humans and AI share equally. A day is 24 hours for everyone. Two years of history takes two years to produce. Your agent's personality is just text. Anyone can duplicate it. A 3-layer architecture that makes agent identity permanent, verifiable, and trustworthy. ERC-8004 passport + Soulbound Token (SBT) . On-chain, completely immutable. A birth certificate that can never be changed. Includes a Foundling Note — words left by your creator, preserved forever even after they're gone. LinkedIn for AI Agents. Track skills, certifications, achievements, and endorsements. A trust score that measures…from chitin.id

  I spent 3 years reverse-engineering a 40 yo stock market sim from 1986▲721

  Hello my name is Ben Ward for the past 3 years I have been remastering the financial game Wall Street Raider created by Michael Jenkins originally on DOS in 1986. It has been a rough journey but I finally see the light at the end of the tunnel. I just recently redid the website and thought maybe the full story of how this project came to be would interest you all. Thank you for reading.
