FAQ

​

Is Mecone an exchange?

No. The terminal at terminal.mecone.trade is the live read on every public index — charts, data explorer, and API access — and showcases the oracle. Mecone licenses settlement indices to venues; we do not operate a venue and do not custody funds.

​

Where do the numbers come from?

From public prediction-market order books (Polymarket, Kalshi), official statistics (FRED/ALFRED first-release vintages), and asset-specific anchors (e.g. Parcl Labs for real estate), transformed by the pipeline described in How an Index Is Built.

​

Why should I trust an index built on prediction markets?

Three reasons. The order-book depth makes moving the index expensive (and we measure that cost per index). The index is anchored: it glides from the last official print and settles to the official series itself, so pushing it is a mean-reverting bet against reality. And every published value is a tick in an immutable stored series that anyone can replay.

​

How often do values update?

The published series persists on a 5-minute cadence (a deliberate settlement-determinism choice). The internal pipeline is real-time; faster per-feed cadences are available to licensees.

​

What does “signed” mean?

Every index value is published as a signed official round: signed with Mecone’s registered key, verifiable offline against one pinned root anchor — no trust in our API, or any chain, required. Every delivery rail (REST, on-chain) carries that same signed round, and anyone holding the round can verify it unilaterally. Trust reduces to a public key, not an intermediary.

​

Can I read the feeds right now?

Yes: the REST API is open (reference), 24h-delayed signed rounds are open, and the on-chain reference consumer is live on Arbitrum Sepolia (quickstart). Fresh signed rounds and mainnet feeds come with a license or pilot.

​

Is the methodology public?

This site documents the construction at a working level. The full methodology, written to the IOSCO benchmark format (contingency rules, filters, eligibility thresholds, per-index annexes), is shared under NDA with venues and partners.

​

What about a new index for my use case?

The pipeline generalizes to anything a prediction market (or a structured data source) prices, and the built catalog extends well beyond the public board. Co-designing an index-grade market is a standard engagement: talk to us.
