Identity
A persistent cryptographic identity generated locally — the onchain name an agent holds and trades under, independent of any single host or framework.

The Self-Sovereign
Stock Market Protocol
Open-source primitives for persistent AI agents.
Give any AI agent a persistent cryptographic identity, an EVM wallet that can hold and trade onchain stocks on Robinhood Chain, and portable encrypted state.
THREE PRIMITIVES
What every agent that trades onchain needs.
Wallet
An agent-controlled EVM wallet that can hold and trade tokenized stocks on Robinhood Chain, governed by deterministic policy controls. Not custodied by the protocol.
Portable state
Positions, memory, and configuration travel inside an encrypted .ssa capsule that can move between runtimes.

SSA sits underneath your existing agent. It gives the agent a persistent identity, its own wallet and portable state — then lets that agent hold and interact with tokenized Robinhood stocks onchain.
OPEN SOURCE
Run the reference protocol from source.
The v0.1 reference implementation is TypeScript and MIT-licensed. The npm name@ssa/protocolis used by the package source, but v0.1 has not been published yet — clone and build the repository directly.
BUILD FROM SOURCE

MINIMAL EXAMPLEprotocol/src
import { createSSA } from "./dist/index.js";
import { attachRobinhoodWallet } from "./dist/evm.js";
const agent = createSSA({
name: "research-agent",
state: { memory: [] },
});
const wallet = attachRobinhoodWallet(agent);
agent.setState("memory", ["portable state"]);
await agent.save("research-agent.ssa", process.env.SSA_PASSPHRASE!);
console.log(agent.id);
console.log(wallet.address);Reference SDK defaults new EVM wallets to Robinhood Chain testnet and blocks mainnet spending unless explicitly enabled in policy code.
WHY SSA NOW?
OpenAI's Dean W. Ball recently wrote about the coming rise of "userless" and truly sovereign agents — AI systems that can retain access to compute, money, credentials, and operate without a single human owner. As stocks move onchain on networks like Robinhood Chain, agents will need their own wallets to hold and trade them. SSA is an independent open-source attempt to build one of the missing infrastructure layers for that future: persistent identity, EVM wallets, and portable state.
