XIDRA White Paper

Equities have moved onchain. Since Robinhood Chain reached mainnet in July 2026, Stock Tokens trade around the clock, settle in seconds, and plug directly into DeFi. Liquidity is spread across AMMs, RFQ venues where professional market makers compete on every quote, and order books. The market never closes, but the people trading it still do.

Today a trader has two options: watch the screen at 3 a.m., or hand their keys to a black-box bot. Neither scales. Brokerage-side AI agents are arriving, but they live inside custodial accounts and are limited to the markets that brokerage serves. Onchain traders need an agent that works on their own wallet, under their own rules.

XIDRA is the agentic trading layer for Robinhood Chain. Our agents read the chart, reason about context, and execute Stock Token trades 24/7 through best-quote routing, without ever taking custody. Every agent runs inside guardrails the user defines (budget, position size, loss limits, allowed tickers, and hours), and every action leaves a verifiable receipt.

Users choose how much autonomy to grant: Copilot Mode proposes trades for one-tap approval, while Autopilot Mode executes on its own within signed, scoped permissions. Beyond the app, the XIDRA Agents API lets wallets and applications embed the same intelligence, routing, and risk layer in their own products.

XIDRA is not another trading bot. It is the agent layer for always-on onchain markets, built first for Stock Tokens on Robinhood Chain.

Tokenized equities are the fastest-growing segment of onchain real-world assets. Tokenized stocks crossed $3 billion in market capitalization in late September 2026, more than four times the roughly $700 million recorded at the start of the year.

Robinhood Chain launched its public mainnet on July 1, 2026 as an Ethereum Layer 2 built on Arbitrum technology. Its Stock Tokens are available through Robinhood Wallet in more than 120 countries, tradable 24/7, and usable across DeFi as collateral or liquidity.

Execution venues are scaling quickly. Arcus, an RFQ exchange on Robinhood Chain, reports over $5 billion in cumulative volume from more than 15,000 traders, and Robinhood Wallet now routes Stock Token swaps through its API.

The rails exist: assets, venues, and wallets. What is missing is the intelligence layer that lets an individual trader participate in a 24/7 market without staying awake for it. That is the layer XIDRA builds.

Always-on markets demand always-on participation. When stocks trade through nights and weekends, price discovery no longer waits for the opening bell. News on a Saturday moves Stock Tokens on a Saturday. A human cannot cover 168 hours a week; an agent bound by clear rules can.

At the same time, execution has become a routing problem. The same Stock Token can be quoted by competing market makers through RFQ, priced by an AMM curve, or matched on an order book. Getting the best fill means comparing venues in real time, a job that is tedious for people and natural for software.

Finally, onchain infrastructure now makes safe delegation possible. Smart accounts and scoped session permissions let a user grant an agent the right to trade specific assets, up to specific limits, for a specific period, and revoke it instantly, without ever handing over a private key.

Onchain Stock Tokens removed the opening bell, the settlement delay, and the borders. They did not remove the human bottleneck. Traders now face:

Stock Tokens turned the equity market into a 24/7, borderless, programmable market. The next step is not another trading screen. It is software that can participate in that market on a trader's behalf, safely.

XIDRA builds that agent layer. Agents that read the market, follow rules the user writes, route to the best quote, and prove every action, all without taking custody.

Starting with Stock Tokens on Robinhood Chain and expanding to every onchain market, XIDRA lets traders own the strategy while their agents cover the hours.
