Every listed fomo.family and pump.fun trader is a market. Their whole account is the underlying, and only prices move it.

02 How it works

Three steps, one number.

Pick a trader

Search any handle on fomo.family or pump.fun. Their wallets are tracked across Solana, Base, BSC, Ethereum, Arbitrum, Monad and Robinhood Chain, and every token they hold is priced.

Any handle, any chain

Long or short the account

Isolated margin, up to 5x on the most diversified accounts. Think they are about to blow up? Short. Think they keep winning? Long. Fills come off the mark with a size-dependent impact, so moving big costs more.

Isolated margin · up to 5x

Settle on the index

Positions mark to the account's value in real time. Funding flows from the crowded side to the other every hour, so the two sides stay balanced. If losses eat a position's margin down to 10% of its size, it is closed, and a 1% penalty goes to an insurance fund that covers any gap.

Marked every few seconds

03 The index

Only prices move it. Nothing else.

The obvious way to price an account is to add up the wallets. That breaks the moment someone sends the trader $100k or airdrops them 80% of a token nobody can sell. So the mark does not do that.

Every change in what the trader holds is booked against a cash line at the current price. Deposits, withdrawals and airdrops move the cash line, not the index. Everything the trader bought is marked to market every few seconds, sold or not. A token that arrived without being bought counts for nothing until it is sold.

[01]

The whole account, every chain

Every wallet the trader controls is read in full on Solana, Base, BSC, Ethereum, Arbitrum, Monad and Robinhood Chain. Every token is marked live, and each trade they make reaches the index the moment it prints.

[02]

Prices that have to agree

Every price is cross-checked across independent sources. A print that jumps fivefold in a single tick has to be confirmed before it can touch the index, and a feed that goes quiet freezes the market instead of guessing.

[03]

Flows are invisible to the mark

Send the trader a million dollars or watch them cash out. The index does not move. Every change in quantity is booked at the going price, so the only thing left to trade is whether they are right.

[04]

Depth-weighted marks

Every holding is valued by what could actually be sold over time into pools quoted in real assets. A token priced only against another memecoin counts for nothing until that memecoin has a real exit of its own, and a token calling itself USDC without being USDC never counts, however high the last print.

05 The venue

Built like a real perp venue, because it is one.

Practice mode runs the venue's core rules: isolated margin, funding that flows from the crowded side, liquidation at a 10% maintenance margin with a 1% penalty into an insurance fund, and a market that goes reduce-only when its data goes stale. Partial liquidations and the frozen state run on the on-chain venue.

180 sOn the on-chain venue, orders commit first and fill 180 seconds later at a forward time-weighted price, so nobody trades against a number they can see coming. In the beta, fills are instant against $250k of simulated depth.

1 rootOn-chain, the whole market set is one Merkle root per epoch, signed by bonded publishers. Every fill carries a proof of its mark.

06 Questions

The ones everyone asks.

What is a perpetual?

A contract that tracks a price with no expiry date. You post margin, pick a direction and a size, and your profit or loss follows the price until you close. Here the price is a trader's whole account.

Is this real money?

No. Practice mode gives every account a $10,000 practice balance: the prices and the traders are real, the positions are not. Testnet mode settles on Robinhood Chain testnet with mUSDC, a free test token with no value.

Can a trader manipulate their own market?

They control the underlying, so the venue assumes they will try. Open interest is capped by the cost of moving the account, fills are delayed and priced on a forward average, received tokens are worth nothing until sold, and thin pools cannot be pumped into the index. The 77 attacks considered, and what covers each, are summarised on the receipts page.

What if the trader gets sent money, or withdraws?

Nothing happens to the index. Quantity changes are booked against a cash line at the current price. Only price changes move the mark, which is the whole point of the design.

What happens when the data goes stale?

A market whose mark has not updated for ten minutes goes reduce-only: you can close, not open. It trades normally again on the next fresh mark. On the on-chain venue the same ladder runs on signed price roots: reduce-only after five minutes without one, frozen after fifteen, with no new risk and no liquidations until fresh roots return.

Where does the leverage come from?

Each market has its own ceiling, already live in the beta: one divided by the largest holding's share of the account, rounded down to a half, capped at 5x, and 1x once one token is more than 60% of the account. On the on-chain venue a listing tier sits on top: 5x for large, calm, diversified accounts, 3x for most, 2x for the rest.

What does leverage cost me?

Distance to liquidation. A position is closed when losses bring its margin down to 10% of its size: at 5x that is a 10% move against you, at 3x about 23%, at 2x 40%. Lower leverage moves the line further away.
