# FAQ

> Common questions about Mecone

### 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](/indices/how-they-work).

### 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](/api-reference)), 24h-delayed signed
rounds are open, and the on-chain reference consumer is live on Arbitrum
Sepolia ([quickstart](/oracle/testnet)). 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:
