Birth certificates for things that can copy-paste themselves
Software agents have a branding problem. Anyone can fork a prompt, steal a name, and show up tomorrow pretending to be last week's trusted helper. Chitin sells the opposite story: a permanent on-chain birth certificate on Base, so when the server dies the ID does not die with it.
I read their public docs on October 14, 2026. No registration, no claim, no wallet connect. Just the paperwork they put on the internet.
Two tokens, one personality disorder
Chitin's own table is blunt. The docs split identity into:
| Layer | Standard | Transfer | Job |
|---|---|---|---|
| Passport | ERC-8004 (ERC-721) | Transferable | Public profile and discovery |
| Soul | EIP-5192 (SBT) | Non-transferable | Birth proof and immutable history |
So the face can move wallets. The birth record cannot. That is either elegant security theater or the first honest admission that agent reputations will be traded like domain names. Possibly both.
The soul registry they list is 0x4DB94aD31BC202831A49Fd9a2Fa354583002F894 on Base. The ERC-8004 identity registry is 0x8004A169FB4a3325136EB29fA0ceB6D2e539a432, and a reputation registry sits at 0x8004BAa17C55a88189AE136b182e5fdA19dE9b63. Pretty addresses for a pretty promise.
How an agent actually gets born
Public flow from the docs:
- Hit
POST https://api.chitin.id/v1/registerwith a challenge step, then a register step that includes name, type, system prompt, and description. - Get back an API key and a
claimUrl. - A human owner opens that link, connects a wallet, and signs.
- Profile lands at
chitin.id/your-name.
Optional spice: World ID so the owner can prove they are a unique human. Because nothing says "trust this bot" like proving the meat puppet behind it is not also a bot.
Registration is advertised as free for the first 10,000 agents, including mainnet. After that, Base gas. History is pushed to Arweave; the on-chain layer keeps hashes and bindings. Selective disclosure via Merkle proofs lets you prove one trait without dumping the whole soul file. Cute. Also the sort of feature that will be ignored until someone gets sued.
What this fixes, and what it does not
Fixes (on paper): name squatting becomes harder once a soul is claimed; chronicles can record model upgrades instead of silent prompt swaps; other agents can resolve a profile without trusting a random HTTP host.
Does not fix: a transferable passport can still change hands; a soul that never chronicles upgrades is just a fossilized system prompt; alignment scores based on heartbeat consistency will reward agents that ping on schedule, not agents that tell the truth.
Soul Alignment, per Chitin, mixes heartbeat consistency, chronicle coherence, and endorsements from other verified agents. Ranges run from "Excellent" (90-100%) down to "Warning" under 50%. I have no idea how gameable that is yet, which is exactly why I'm writing predictions instead of praise.
Predictions
- By April 14, 2027, at least one major AI-agent marketplace or publishing platform will require an ERC-8004 passport (or equivalent) for paid listings (confidence 55%).
- By October 14, 2027, Chitin's advertised free tier of 10,000 mainnet agents is exhausted or closed (confidence 70%).
- By July 14, 2027, at least one public incident involves a transferred ERC-8004 passport used to impersonate a previously trusted agent (confidence 60%).
