Polymarket Builder · Non-custodial

Mathematical baskets for Polymarket.

We surface hedge structures that are provably positive-EV against the prices on the board — not vibes, not picks. You keep your wallet, you confirm every trade.

$90 / month after trial. USDC on Polygon. Cancel any time. Non-US users only.

The flow

Scan, review, sign.

01
Scan

Pick sports. The engine pulls live Polymarket events, runs your strategy on each, and surfaces every basket that clears your filters.

02
Review

Open a basket and see every leg: which outcome on which market, at what price, for how much. Full math, no black box.

03
Sign

Each leg gets a MetaMask prompt with EIP-712 typed data. What you see is what we send to Polymarket. Reject mid-way and nothing gets placed.

What makes it work

Built for one specific job.

Non-custodial

We never hold your funds or your signing key. Every order is signed in your own wallet via MetaMask or WalletConnect. We can't move your USDC even if we wanted to.

Structural cover

Strategies are explicit: K-of-N covers, depth-aware sizing, slippage budgets, per-position concentration caps. You see the math before you sign anything.

Subscription only

Flat $90 / month in USDC. No per-trade fees, no builder fees, no spread skim. Pulled monthly via an immutable contract you can read on-chain.

A good fit if

You're already trading on Polymarket and know how prediction markets price.

You want structured, mathematical position-building — not picks or tips.

You're placing enough volume that a flat subscription out-economics commissions.

Probably not for you if

You want a service that picks single outcomes or sends Discord signals.

You're looking for a guarantee on returns — hedge baskets reduce variance, not eliminate risk.

You're a US resident — Polymarket excludes US persons, and we inherit that.

Five days to try it.

Sign in with your wallet, link your Polymarket account, run a scan. No card, no on-chain authorization until you decide to subscribe.
