Coins paired with a position, an asset, or both

The whole mechanism, end to end: how a pump.fun coin's creator fees run a leveraged position that burns the supply, buy a real asset and airdrop it to holders, or do both at once.

01

Overview

Fuzed is a launchpad on top of pump.fun. Every coin launched through it is paired with something real, funded by the coin's own creator fees. There are three kinds of coin:

  • Leveraged position. The fees run a long or short perpetual on Phoenix. The deployer picks the market, the side and the leverage once, at launch; from the first trade the fees open and grow that position, take profits, and buy back and burn the coin's supply.
  • Asset rewards. The fees buy a real asset on Jupiter, a tokenized stock, a pre-IPO share, an ETF, a commodity or a major crypto, and pay it out to the coin's holders, pro-rata. Nothing is burned; holders are paid in the asset itself.
  • Mix. Both engines on the same coin. 40% of every sweep grows the position, 40% buys the asset for holders, and the coin takes no protocol share at all.

The coin itself is a bone-stock pump.fun token. Everything Fuzed adds lives off to the side, in a keeper-run treasury whose every action is a public transaction. There is no custody of user balances and no custom token code to trust.

02

The launch

A launch is a single transaction on pump.fun's own program: standard token, standard bonding curve quoted in SOL, graduation to PumpSwap with the pool locked by pump.fun itself.

There are three ways to sign it. They differ only in who pays for the launch and who sits on the creator side of it:

  • X login. Signing in with X gets you a self-custodial wallet from Privy: only you can access it, we never can. No extension and no seed phrase. That wallet pays for the launch, takes your dev-buy, and earns the 15% creator share.
  • Your own wallet. Any Solana wallet through the Wallet Standard (Phantom, Solflare, Backpack). It pays, it takes the dev-buy, it keeps the 15%.
  • No login. Nothing to connect and nothing to sign. Fuzed launches the coin from the platform wallet with no dev-buy, so you pay nothing and hold nothing, and that wallet is the on-chain creator that takes the 15%. The engine runs exactly as it does on any other coin.

Atomically in the same transaction, 100% of the coin's creator rewards are locked to a per-coin engine sub-wallet, the treasury the keeper runs. It shows on pump.fun and every terminal as "Creator rewards: Locked". Nobody, deployer included, can redirect them afterwards.

The deployer first picks the kind of coin, then its engine, both immutable for the life of the coin. For a leveraged coin: the underlying market, long or short, and a leverage from 1x up to the venue ceiling for that market (clamped a half-step under the cap so a small move never sits on the liquidation line). For a reward coin: the asset its holders will be paid in. For a mix: both.

03

The engine sub-wallet

Every coin gets its own treasury sub-wallet, derived deterministically inside the keeper. The key is never stored in a database, never sent to a browser, never shown to the deployer. That wallet is the coin's on-chain creator, so pump.fun routes the fees to it, and on a coin that runs a position it is also the owner of the Phoenix account.

The venue only accepts orders signed by the account owner, so nobody can close, drain or borrow against a coin's position: not the deployer, not the creator of any other coin, not us through any UI. The engine runs on a fixed public policy or not at all.

04

The fee split

The keeper sweeps a coin's fee vault whenever it holds at least $25 (claiming pennies would hand most of it to transaction costs). Each sweep splits the same way, on the same tick. A leveraged coin:

  • 50% to the perp treasury: opens the position, then tops up collateral
  • 20% to the coin's own buyback-and-burn reserve
  • 15% to the deployer, paid straight to their wallet, for the life of the token
  • 15% to protocol: 10% ops & marketing, 5% buys back and burns $FUZED, the protocol token

A reward coin runs no perp and burns nothing, so its split is simpler:

  • 70% to the rewards pool: buys the paired asset and airdrops it to holders
  • 15% to the deployer, paid straight to their wallet, for the life of the token
  • 15% to protocol: 10% ops & marketing, 5% buys back and burns $FUZED

A mix coin runs both engines, and is the only kind that pays the protocol nothing:

  • 40% to the perp treasury
  • 40% to the rewards pool
  • 10% to the deployer
  • 10% to the coin's buyback-and-burn reserve
05

Reward coins: paying holders in a real asset

A reward coin pairs a pump.fun coin with something that already trades on its own: a tokenized stock (an xStock such as NVDAx or TSLAx), a pre-IPO share, an ETF, a commodity, or a major crypto. These are real mints on Solana, taken from Jupiter's own catalogue rather than a list we invented. Instead of running a position, the coin's fees buy that asset and hand it to the people holding the coin.

The rewards pool (70% of every sweep) accumulates in the sub-wallet. When it is worth at least $25, the keeper runs a payout round:

  • · it snapshots every wallet holding the coin, excluding program-owned accounts (the bonding curve, the PumpSwap pool, vaults). There is no minimum holding
  • · it buys the asset on Jupiter with the pool, keeping back only what the round will actually spend on token-account rent and fees
  • · it divides what it bought by how much of the coin each wallet holds, and transfers it, creating the wallet's token account when it has none, a few recipients per transaction
  • · a share worth less than opening that account is not sent. It is recorded against that wallet and paid in full the round it grows past the cost, so it is never redivided among the larger holders

Every round is a set of public transactions linked from the coin page: the swap that bought the asset and the transfers that paid it out. Whatever cannot be paid in a round (dust, a failed batch) stays in the wallet and joins the next one.

More than one asset, more than one position

A coin can pair with up to three assets instead of one. Rounds then rotate: each full pool buys ONE of the assets, the next pool buys the next, in the order they were picked at launch. Nothing is split thin: a rotating coin's round is exactly as large as a single-asset coin's, every holder receives every asset over time, and the coin page always names the asset the next round will buy. Withheld small shares are tracked per asset, so what you are owed in one stock never mixes with what you are owed in another. Like everything else about the engine, the asset list is set at launch and immutable.

The same goes for leveraged positions: a coin can run up to three, each on its own market with its own side and leverage. They fund in order, the first opens at its gate before the next starts saving, and once all are open the fees rotate to the least-funded one. Every position keeps its own collateral, its own liquidation price and its own take-profit ladder, and the coin page shows one card per position.

06

Mix coins: both engines at once

A mix coin runs both engines on the same token. Every sweep sends 40% to the perp treasury and 40% to the rewards pool, so the position grows and the holders get paid out of the same fees, on the same tick. The remaining fifth is 10% to the deployer and 10%to the coin's burn reserve.

It is the only kind that takes no protocol share: no ops slice, no $FUZED buyback. Realized take-profit follows the same logic. Where a leveraged coin splits profit 70 burn / 15 creator / 15 ops, a mix coin folds the ops slice into its own burn and splits it 85 / 15.

Nothing else changes. The position obeys the same lifecycle, take-profit ladder and underwater rules; payout rounds obey the same pro-rata and rent rules. A mix coin simply funds both engines at half weight, and the choice is made once, at launch, like every other engine setting.

07

The venue: Phoenix

Positions execute on Phoenix (Ellipsis Labs), the on-chain perpetuals venue on Solana. It offers 60+ markets across crypto majors, SOL-ecosystem tokens, memes, tokenized stocks (NVDA, TSLA, HOOD and more) and commodities, each with its own leverage ceiling, up to 40x on the deepest.

Collateral is USDC. On each perp-leg credit the keeper swaps the SOL to USDC in the same tick, so the treasury is dollar-denominated and independent of which coin it backs. Positions are isolated: each coin's collateral backs only its own position.

08

The venue: Jupiter

Every swap the keeper makes goes through Jupiter, the aggregator that routes across Solana's liquidity rather than holding any of its own. Four legs use it: SOL to USDC for perp collateral, SOL to the paired asset for a reward round, SOL to the coin for a buyback, and SOL to $FUZED for the protocol flywheel.

The asset catalogue on the launch page is Jupiter's own token list, filtered to the tokenized-asset issuers (Backed xStocks, PreStocks, Backpack Securities) plus a curated set of major crypto, and then to a liquidity floor of $25k so nothing unfillable can be picked. If Jupiter cannot route an asset, it does not appear.

Slippage is set per leg rather than as one loose default for all of them, and every swap is an ordinary public transaction linked from the coin page.

09

Position lifecycle

Open.Once $20 of perp-leg fees have accrued, the keeper opens the position with that collateral at the coin's chosen market, side and leverage.

Top-up.Every further $20 of fees adds collateral to the same position at the same leverage, so it grows with the coin's volume without ever ratcheting leverage up.

Permanence. The position stays open for the life of the token. There is no graduation event that unwinds it. When the coin graduates to PumpSwap the fee source switches legs, and the engine does not blink.

10

The take-profit ladder

The keeper marks the position to market every few seconds and keeps a high-water mark of realized profit. Each time floating profit climbs another +25% of current collateral above that mark, it closes 20% of the position (size and collateral scale down together, so nominal leverage is preserved) and sets a new mark.

Each realized profit is withdrawn from the venue, never re-added to collateral, swapped to SOL and split: 70%to the coin's buyback reserve, 15% to the creator, 15%to protocol ops & marketing. It is a ratcheting ladder: gains are progressively converted into burns while the position keeps running.

Two coins bend that split, each to match its own fee split rather than to invent a new rule. A mix coin takes no protocol share, so the ops slice folds into its burn (85 / 15). On $FUZED itself the creator share folds into its burn instead (85 / 15).

11

Buyback & burn

The 20% fee slice plus 70% of realized profits accrue in a per-coin reserve. Once it crosses $25, the keeper swaps that SOL to the coin on the open market and burns the tokens on-chain. A single tick spends at most $25, so a large reserve drains as a series of ordinary buys rather than one block-moving order.

Burn money is ring-fenced: once earmarked for a burn it is excluded from everything the keeper can attach as perp collateral. It can only leave the sub-wallet as a buyback and burn. Profit destined for holders is never re-risked on the position it came from.

12

Underwater mode

"Underwater" simply means the position is currently losing: for a long, the price sits below the entry. The engine treats fees differently depending on which side of entry the price is on.

While the position is winning, each sweep adds size at the coin's leverage, so the position grows. While it is underwater, the same sweep attaches as (almost) pure collateral instead: no new exposure, just a bigger cushion. Equity rises, effective leverage falls, and the liquidation price moves further away from the market.

Concretely: a 5x SOL long from $100 with SOL at $85 might sit $5 from liquidation at $80. Buying more SOL there would grow the risk at the worst moment. Attaching the fees as collateral instead walks the liquidation price down, $80, then $72, then $63, while the price hasn't moved. The same drawdown gets safer with every sweep. And the keeper never sells into a loss: no stop-loss, no panic close.

Sizing is always computed against equity, collateral minus any unrealized loss, the same basis the venue margins on. Each tick also caps how much exposure it can add, so a large top-up ladders in over several ticks instead of levering up in one step.

13

Liquidation

Leverage cuts both ways. A high-leverage position on the wrong side of a fast move can be liquidated by the venue. When that happens it is recorded as a public event on the coin's page, and the engine rebuilds a fresh position from the next $20 of fees.

The fee-funded burn continues the whole time, liquidation or not, so the coin keeps tightening its supply even while a position is being rebuilt. On a mix coin the reward rounds keep running too: the two engines are funded separately and neither waits on the other.

14

The keeper

A keeper bot ticks continuously. For every active coin, each tick it:

  • · refreshes the coin's market cap and bonding-curve progress;
  • · claims fees past the sweep gate and applies that coin's split;
  • · marks the live position and runs the take-profit ladder;
  • · opens, tops up, or deleverages the position as the rules dictate;
  • · runs a reward round once the pool is worth $25, on a reward or mix coin;
  • · drains the burn reserve past $25: swap to the coin, burn on-chain.

Every step is fail-soft per coin: one coin's RPC hiccup never stalls the rest.

15

What you can verify

Every sub-wallet address is public and linked from its coin page. Fee claims, swaps, top-ups, take-profits, reward payouts, buybacks and burns are all ordinary mainnet transactions, linked from the coin's history feed. The live perp position is on-chain and rendered on the page: side, leverage, collateral, unrealized PnL, liquidation price, and total bought back and burned.

SOL in matches fee claims and realized profits; SOL out matches swaps, deposits, payouts and burns. Anyone can reconcile a coin's entire treasury from the explorer, without trusting us.

16

Risks

Leverage can be liquidated. pump.fun, Phoenix, Jupiter and RPC providers are live dependencies; an outage on any of them can pause sweeps, top-ups, payouts or burns. None of this touches user balances. Fuzed custodies no user funds and no token supply.

A reward coin depends on its paired asset: the issuer, its on-chain liquidity and its price. Rewards land only when a round runs. A very small holding still earns its exact share, but the share waits in the treasury until it is worth more than the rent deposit that opening a token account locks up, so the smallest holders are paid rarely and in larger amounts rather than every round.

A tokenized stock is a Token-2022 mint and its issuer keeps real powers over it: a permanent delegate that can move the token out of any wallet, a pause switch that stops every transfer, and a freeze authority. Those are the issuer's, not ours, and they apply to the asset in your wallet exactly as they would if you had bought it yourself. A pause only delays a payout round; the asset waits in the treasury and goes out when transfers resume.

A coin paired with an engine is still a memecoin. Pick a market, a side and a leverage, or an asset, or both, and a coin you actually believe in.
