Introducing Fill Memecoins that trade stocks for you. Launch a token on any Robinhood Chain launchpad. Its creator fees are automatically claimed by an autonomous engine that opens leveraged stock perpetual positions on Ostium — a permissionless RWA perp DEX on Arbitrum. Profits buy back and burn your token on Uniswap. fill.fun ━━━━━━━━━━━━━━━━━━ HOW IT WORKS 1⃣ Launch a token on Pons (pons.family) with the Creator wallet set to the Fill protocol address. Also works with LaunchHood, Robinlaunch, and NOXA (coming soon). 2⃣ Register at fill.fun/launch — Fill verifies on-chain that the token's creator fees actually route to the protocol wallet. Factory contract lookup, not trust. 3⃣ The engine activates. Five autonomous workers start running 24/7: • Fee Claimer — claims accumulated creator fees every 3-5 min from every registered token's Pons locker + factory contract • Position Manager — evaluates stock signals, opens leveraged perps on Ostium, manages a 3-stage exit system • Buyback Engine — swaps profits + fee allocations for tokens on Uniswap, burns them to a dead address permanently • Risk Manager — monitors every open position for liquidation proximity, drawdown breaches, and circuit-breaker events • Token Discovery — auto-scans all supported launchpads and registers any new token that points creator fees at the protocol wallet Zero human intervention after launch. The code runs. The engine trades. The supply burns. ━━━━━━━━━━━━━━━━━━ FEE ARCHITECTURE Creator fees split 70/30: → 70% funds stock perp positions on Ostium → 30% buys back + burns the FILL protocol token When perp positions take profit, those profits split 70/30 again: → 70% of profits buy back YOUR derivative token (the one whose fees funded the trade) → 30% of profits buy back FILL Both tokens have continuous, autonomous buy pressure from every cycle. Supply decreases every time the buyback engine runs. ━━━━━━━━━━━━━━━━━━ STRATEGY MODES Every token picks its risk profile at launch: 🟢 Conservative • 3-10x leverage • US market hours only (market open, power hour, regular hours) • Strong signals only (+15 entry bonus threshold) • Tight stop: -25% of collateral 🟡 Balanced • 5-25x leverage • Trades most sessions • Standard stop: -40% of collateral 🔴 Degen (default) • Signal-driven, up to 50x • Trades 24/7 around the clock • Stop: -40% of collateral ⚪ Off • No trading at all • Fees go directly to buybacks only The leverage you set at registration is a hard cap. Every trade sizes at min(signal strength, strategy range, your cap). Existing positions are ALWAYS risk-managed regardless of mode — the mode only gates new entries. ━━━━━━━━━━━━━━━━━━ THE TRADING ENGINE The Position Manager runs a stock scalping strategy called "Smart Degen v4": Entry: • 8-signal market analysis: EMA crossovers (1m), RSI (context-aware), MACD (trend confirmation), higher timeframe trend (15m + 1H EMA), ATR volatility, session timing, volume confirmation, and recent price action • Scores from -100 to +100 with recommended leverage • Yahoo Finance candle data across 3 timeframes (1m, 15m, 1H) • Max 3 concurrent markets to prevent correlated concentration Exit (3-stage DCA system): • Stage 1: close 25% at +0.5% price move, move stop-loss to breakeven • Stage 2: close 25% more at +1.0% price move • Stage 3: trail remaining 50% with a 0.5% callback from highs • Hard stop-loss at -40% of collateral (before liquidation) • Fast profit-checker runs every 60-90 seconds Never adds to a losing position. Cooldown after a loss before re-entering. Safety: the engine checks on-chain before retrying failed transactions — prevents double-fire risk where a trade lands but the RPC response times out. ━━━━━━━━━━━━━━━━━━ RISK MANAGEMENT The Risk Manager runs every 5-10 minutes and enforces: ① Liquidation proximity — if collateral ratio drops below 5% of position notional, emergency reduce 50% of the position immediately ② Max drawdown — if unrealized loss exceeds 80% of deployed capital, auto-reduce position by 25% ③ Circuit breaker — if the stock makes an extreme adverse move (90%+ against entry), full close + pause the token ④ Orphan sweep — scans for any positions not covered by the normal token loop, so no deployed capital ever escapes risk checks ⑤ Stale detection — flags positions with no recent updates Trading capital is capped at $1,500 USDC total across all markets. A gas buffer (0.002 ETH minimum) is always reserved — the engine will never deploy funds if it would drain the wallet below gas level. ━━━━━━━━━━━━━━━━━━ AVAILABLE STOCK PERPS 14 markets, all via Ostium on Arbitrum One: AAPL · TSLA · NVDA · MSFT · GOOG · AMZN · META HOOD · COIN · MSTR · NFLX · AMD · PLTR · AVGO Permissionless.
