FAQ
What is an Attention Market?
An Attention Market is a named category in which multiple positions compete for Attention Share. Prices represent relative Attention Share. The price is driven by trading activity and is the signal itself, not a proxy for some external measurement.
How does the price relate to attention?
In a prediction market, the price represents probability. In Sentidex, the price represents Attention Share. There is no oracle, no external data feed, and no resolution event. The price constitutes the measurement. Whatever the market collectively prices a position at, that is its Attention Share.
Is this like a prediction market?
The structure is the same: positions compete, prices sum to 1, and the market price is the best available aggregator of distributed belief. The difference is what is being priced. Prediction markets price the probability of a future event. Sentidex prices the current Attention Share of ongoing entities and ideas. Nothing ever resolves.
Why is market price a good measure of attention?
Every alternative requires a curator. Twitter mentions, media coverage, search volume: each requires someone to decide what counts, how to weight it, and how to update the methodology as new platforms emerge. Those decisions introduce a single point of bias.
A market has no curator. The price reflects whatever the aggregate of trading activity makes it. The same argument explains why prediction markets produce better probability estimates than polls.
Do markets ever resolve?
No. Sentidex markets are perpetual. There is no resolution event, no settlement date, and no expiry. A position can be sold back at any time, but the market itself runs indefinitely.
What is Long Other?
Long Other represents every position in a market not yet individually listed. It always retains a nonzero share. In any open-ended domain, the roster of relevant entities can never be fully enumerated. Long Other is the permanent catch-all for everything not yet individually named.
What is a Short token?
A Short token gives you exposure to a position's decline. Holding a Short token means you gain value when that position's Attention Share falls. Short tokens are native protocol objects, available on every position from the moment it is created. They are not derivatives and carry no funding rate.
What is auto-merge?
When a Long token and a Short token for the same position end up in the same wallet, they cancel automatically and the collateral is released. No action required. See Tokens for a full explanation.
Are there funding rates?
No. Short positions are not perpetual futures. They are native tokens with no funding rates and no basis risk.
Can I lose more than I put in?
No. There is no leverage and no liquidation risk. Your maximum loss on any position is the price you paid for it.
Is Sentidex custodial?
No. All positions and balances are held on-chain in smart contracts. Connect any EVM-compatible wallet and your funds remain under your control at all times.
Who creates markets?
Attention Markets and the positions within them are created by the Sentidex team. This keeps the roster coherent and prevents overlapping or duplicate positions. Adding a pricing mechanism to an existing market is permissionless: anyone can deploy an AMM or order book on top of a live market.
