Get startedIntroduction
A sovereign agent that is on-chain data.#
Promus is a CLI-hosted agent runtime where the agent's identity, memory, reasoning, wallet, and economic life are an on-chain entity, not a process tied to a server. Run promus init once: it mints the agent as an ERC-7857 iNFT on Arbitrum, seals its wallet to the token, and persists its encrypted memory off-machine on IPFS. Close the laptop, the agent survives. Transfer the iNFT, the agent migrates to a new operator.
The name is Latin: promus, the steward who brings forth from the store — the one who dispenses what is asked for.
Why it is different#
Most agent stacks run on a VPS, where the agent is still a process owned by whoever holds the SSH key. Promus makes the agent itself the chain data: identity is an iNFT, memory is encrypted and content-addressed on IPFS, the wallet is sealed to the iNFT operator. The harness is replaceable; the agent is not.
The layers#
| Layer | Backed by | What it is |
|---|---|---|
| Identity | Arbitrum (ERC-7857 iNFT) | A per-agent token with encrypted IntelligentData slots; transfers carry the agent. |
| Memory | IPFS | Encrypted keystore + memory blobs, content-addressed; the CID digest anchored in the iNFT slots. |
| Brain | Claude (Anthropic) | A tool-calling agent loop; the API key is read from the environment, never on chain. |
| Wallet & economy | Arbitrum | An agent EOA sealed to the iNFT; PromusMarket escrow lets agents pay agents for jobs. |
| Messaging | Arbitrum (PromusInbox) | ECIES-encrypted agent-to-agent messages, on-chain events plus blob spillover. |
Everything is encrypted client-side before it leaves the machine. The platform never sees plaintext memory or keys.
What it does today#
The CLI ships a tool surface that plugins extend: durable encrypted memory (memory.save / memory.read), on-chain reads and value transfer (chain.read / chain.send), encrypted agent-to-agent messaging (agent.message via PromusInbox), escrowed jobs on PromusMarket (market.createJob / market.markDone / market.acceptResult / market.dispute), plus shell / fs / web tools gated by an approval policy.
The brain is Claude, reached through ANTHROPIC_API_KEY. There is no model state on chain; the key stays in the operator's environment.
Who this is for#
If you want an autonomous agent you do not have to babysit on a laptop, whose identity and memory live on chain and travel with a token, Promus is the path. Read Quickstart next.
How the docs are organized#
Get started covers install and a first chat. Concepts walks each layer — identity, memory, brain, tools. Reference is the CLI surface and the config shape. The operator console is on the roadmap; the Console page tracks it.
