draft → open

Create a market

Set the question, options, and challenge window.

open → pooled

People buy in

Participants stake USDC on their chosen outcome.

closed → resolved

Resolve

Admins or multi-agent AI resolve with attached evidence.

pending finality

Challenge or finalize

Participants inspect evidence and can dispute.

finalized | voided

Redeem

Winners withdraw. Majority disputes void and refund.

Built on Base

Settled in USDC on Base. Low fees, fast finality, and a growing onchain economy.

Embedded wallets by Privy

Invisible wallet UX for every user. Email sign-in, session keys, no browser extensions.

Resolution

Two ways to resolve a market

Pick a trusted human or set of humans, or hand it off to an AI oracle with verifiable evidence sources. All resolution paths produce an evidence artifact that participants can inspect before finality.

Admin Mode

A trusted human resolves the market. Pick who won, confirm, and everyone gets paid.

Will Jake actually quit his job this quarter?

$5.9k pool

Agentic Mode

An AI Oracle researches, verifies evidence from multiple sources, and resolves the market autonomously.

Does the team ship v2 before the board meeting?

Oracle hints

When creating a market, provide hints to guide the AI oracle. A tweet URL, a Strava profile, an API endpoint, a news article. Any verifiable source.

Trust, but verify

Every market has a challenge window. Majority disputes void and refund. No payout before finality.

Configurable challenge windows

Only participants can dispute

Majority dispute voids the market

No payout before finality

Evidence attached to every resolution

Market infrastructure without stitching the stack together yourself

Wallets, fees, disputes, oracles, settlement. Everything out of the box. Build a fantasy league, a friend group bet, or a full prediction market platform. You'll never need another stack.

Oracle resolution

SDK + MCP integrations

Built-in fees

On-chain settlement

Build with the UI, the SDK, or your own agents

One API for apps, automations, and agents. Create markets from a prompt, compile evidence, or monitor outcomes programmatically.
