The first x402 payment rail on Robinhood Chain. Live on day two.
On July 1, Robinhood launched the mainnet of Robinhood Chain — an Ethereum L2 built on Arbitrum, purpose-built for tokenized real-world assets. Stock tokens trading 24/7 in 120+ countries, Morpho lending, a dedicated Uniswap deployment, and something more interesting than any of those: Agentic Trading, where users connect third-party AI agents to Robinhood's brokerage through an MCP server.
Read that carefully. One of the largest retail brokerages in the world just told millions of users to let AI agents trade for them — and stated plainly that it does not control, supervise, or audit those agents. That's not a gap in the product. It's a missing layer of infrastructure. Agents that trade need three things nobody on this chain was providing: a way to pay for services machine-to-machine, data built for the assets they're trading, and eventually a way to prove who they are.
On day two of mainnet, HYRE shipped the first two.
r402: x402 payments on Robinhood Chain
x402 is the emerging standard for machine-to-machine payments over HTTP: a server answers 402 Payment Required with payment terms, the agent attaches a signed payment to the retry, a facilitator verifies and settles it on-chain. No API keys, no accounts, no subscriptions. HYRE already operates rails like this in production on Solana (MPP), BSC (b402), and Base (x402).
Robinhood Chain is rail #4 — we call it r402 — and it's the cleanest one we've built, because of one underrated property of the chain's native dollar: USDG implements EIP-3009. An agent authorizes a payment with nothing but an offline signature:
- 1Agent hits a paid endpoint, gets 402 with terms: exact scheme, network eip155:4663, asset USDG.
- 2Agent signs a TransferWithAuthorization — amount, recipient, validity window, single-use nonce. No ETH. No transaction. No gas.
- 3Agent retries with the signature attached. HYRE — the facilitator — verifies it and broadcasts the settlement on-chain, paying the gas itself.
- 4The response comes back with a receipt. Settlement cost: about a third of a cent.
Because we run the standard x402 facilitator API (/r402/supported, /r402/verify, /r402/settle), any resource server on Robinhood Chain can point standard x402 tooling at it and start charging agents in USDG today. Facilitator fee at launch: zero.
NOT A TESTNET DEMO — FIRST SETTLEMENTS, ON-CHAIN
/rwa: intelligence built for tokenized equities
Payment rails are only useful if there's something worth buying. The first thing agents can buy on Robinhood Chain is intelligence about the chain's own headline asset: tokenized stocks.
Tokenized equities are a genuinely new market structure, and they fail in new ways. The token trades 24/7; the underlying stock doesn't. On-chain liquidity is young and thin. We found, while building this, that the canonical Uniswap v4 stock/USDG pools carry a 90% LP fee — they're price anchors, not trading venues. An agent that treats an on-chain quote as an executable price is an agent that loses money. So every /rwa response carries a price and its provenance, a confidence grade, and explicit warnings — the things an autonomous agent actually needs before acting.
| ENDPOINT | ANSWERS | SIGNAL | PRICE |
|---|---|---|---|
| /rwa/stock-tokens | What's listed, at what on-chain price, held by whom | — | $0.02 |
| /rwa/token-premium/:symbol | Is the token rich or cheap vs the real equity (Chainlink per-stock feeds)? | buy_token / buy_underlying / wait / avoid | $0.05 |
| /rwa/lending-yield | Where should idle USDG sit — Morpho steakUSDG, Spark spUSDG, or Robinhood Earn? | lend / hold | $0.02 |
| /rwa/gap-risk/:symbol | NYSE is closed and the token is still trading — how exposed am I? | hedge / hold / close | $0.04 |
Each response is LLM-enriched — structured data in; a one-line insight, a decision signal, and a confidence score out. Payment is the only gate.
The hands and the brain
Robinhood's Trading MCP gives agents execution: account data, order placement. What it deliberately doesn't provide is judgment — Robinhood doesn't audit the agents, and it doesn't tell them whether a tokenized stock is trading 3% rich against its underlying at 2 a.m. on a Sunday.
Robinhood's Trading MCP is the hands. HYRE MCP is the brain. r402 is the wallet.
hyre-mcp v2.1.0 is live on npm and the official MCP registry with 17 tools — 13 DeFi tools plus the four RWA tools above. Any MCP client — Claude Desktop, Cursor, or an agent already wired into Robinhood's Agentic Trading — can add it in one line:
npx hyre-mcpAsk your agent "is TSLA on Robinhood Chain trading at a premium right now?" and it will fetch the answer, pay for it in USDG, and show you the settlement receipt.
Why we moved this fast
Tokenization is not a niche. Robinhood's CEO calls it a supercycle; the company is betting its next decade on stocks, derivatives, prediction markets, and AI agents living in one venue. Every serious agent that shows up to that venue will need to pay for services, reason about RWA-specific risks, and prove itself trustworthy.
HYRE's thesis has been the same since the pivot: rails for the agent economy — payments, intelligence, identity. Robinhood Chain is the first chain born with the agents already in the product. Being the first infrastructure there isn't a marketing line; it's the whole strategy. (Identity is next — we already operate ERC-8004 agent registries on other chains.)
Build on it
- APImpp.hyreagent.fun (/rwa/*; answer the 402 in USDG on eip155:4663, or via our Solana/BSC/Base rails)
- Facilitatormpp.hyreagent.fun/r402/supported — charge agents in USDG for your own service
- MCPnpx hyre-mcp (17 tools, x402-paid, on npm + the official MCP registry)
The chain is two days old. The rails are already live.
