The screens

The dashboards, not a pitch deck

Screenshots are the seeded demo — the same pages you open with Try demo. They follow light, dim, and dark. Real captures, including Discover Wallets.

poly.twentyfirst.trading/dashboard

Poly overview dashboard
Poly overview — KPIs, equity curve, and live activity
Product depth

Separate execution stacks. One design system. Shared authentication.

Prediction markets and equities have different venues and risk models, so the apps stay split. The UI, the shortcuts and the login do not. Agents use the same authenticated APIs through one MCP.

Poly
Taker-only copy
Mirror wallets as taker orders with per-target limits. Maker liquidity-reward fills are excluded, and the LP guardrail warns or blocks copy when a source looks like an LP wallet.
Five modules
NO farming, arbitrage, mean reversion, near-resolution, and Liquidity Rewards. The first four take the book. LP observes live rewards and runs an honest paper maker — live rest is not shipped.
Discover Wallets
Official Polymarket PnL, our profitability score, and an LP versus taker split so you can rank wallets before you copy them.
Data terminal
News, sports, crypto, politics, science, and culture feeds on the same desk as the book — context without leaving the terminal.
AI assistant
Ask about your book. The assistant can propose trades and navigation for your approval.
Instant settlement
On-chain resolution detection settles paper and live positions in seconds.
Stocks
Alpaca execution
Paper or live broker accounts for balances, positions, and guarded orders.
Congress, Form 4, PDMR
Follow U.S. Congress, SEC Form 4, and EU PDMR (DE) disclosures, then stage or auto-size equities orders.
AI hedge fund
Multi-analyst pipeline that proposes a book you can review before sending.
Pattern Lab
Seasonality and session studies across a symbol universe with ranked edges.
Risk-first defaults
Automation stays behind limits, review modes, and audit logs.
Shared terminal UX
Same layouts and navigation as Poly so switching products is instant.
Architecture

A monorepo you can actually run.

Shared SSO on twentyfirst.trading moves you between desks without re-authenticating. Everything below the session is deliberately separate.

01

Apps

landing · poly · stocks — three Next.js 16 hosts, one SSO cookie. MCP on 3027 wraps the same APIs.

02

Data

PostgreSQL 16 + Drizzle. Shared users table; product tables stay isolated.

03

Workers

BullMQ on Redis for taker-only copy, five modules including LP observe, settlement, and hedge runs.

04

Venues

Polymarket CLOB + Polygon CTF events. Alpaca paper/live for equities.

MCP

One agent surface for both desks.

Cursor and other agents talk to Poly and Stocks through one Streamable HTTP MCP. User tokens run as you. Admin tokens can flip Discover and sampler flags in Redis without a restart. Live capital writes need confirmLive=true and never work on the demo account.

Workflow

Public demo first. Request access when you want live capital.

The paper terminal is open to anyone. Live trading is issued per account so execution stays sane across shared venues.

FAQ

Questions we actually get

A seeded account (demo@twentyfirst.trading) signs into the real Poly and Stocks apps. Poly shows paper markets, strategies, Discover Wallets, and copy history. Stocks returns fixture broker data so the dashboards look complete without Alpaca keys. Live trading, wallets, and billing stay disabled.
