Fill Protocol

Stock-Perp-Backed Token Derivatives on Robinhood Chain

Overview

Fill Protocol is an autonomous on-chain system that transforms idle creator fees from Pons launchpad tokens into leveraged stock perpetual positions on Ostium (Arbitrum). Profits generated from these positions are used to buy back the creator's token on the open market, creating sustained pressure without requiring any action from the token creator or holders.

Key Principle: Creator fees flow in. Leveraged yield flows out. Tokens get bought back on the open market. Fully automated. Fully on-chain.

How It Works

The protocol operates in a continuous three-phase cycle:

Fee Collection — When a creator deploys a token on Pons (Creator wallet field) or LaunchHood (Reward recipient field) pointed at the Fill protocol wallet, all creator fees from that token are automatically routed to Fill.
Perpetual Deployment — Collected fees are deployed into leveraged stock perpetual positions on Ostium — a permissionless RWA perp DEX on Arbitrum — based on the creator's chosen stock, direction, and leverage level.
Buybacks — When positions are profitable, gains are harvested, used to buy the creator's token on the open market, and the purchased tokens are permanently burned by sending them to a dead address.

Fee Engine

The Fill fee engine is a background service that monitors Robinhood Chain for claimable creator fees on registered tokens. When fees accumulate past a configurable threshold, they are automatically claimed and converted to the appropriate collateral for perpetual position entry.

Fee Distribution

70% — Deployed into stock perp positions as collateral (profits flow to token buyback + burn)
30% — Direct FILL buyback

Perpetual Strategy

Each registered token is assigned a perpetual trading strategy based on the parameters chosen during registration:

Underlying Stock — The stock the perpetual position tracks (e.g., AAPL, TSLA, NVDA, HOOD).
Direction — Currently LONG only. Short positions are under development.
Leverage — From 5x up to 50x on Ostium.

Strategy Modes

Each token chooses how aggressively the engine trades its fees. Existing positions are always risk-managed regardless of mode — the mode only gates new entries.

Conservative — 3-10x, regular US market hours only, requires stronger signals, exits at -25% of collateral.
Balanced — 5-25x, trades most sessions, standard -40% stop.
Degen — signal-driven leverage up to 50x, trades around the clock.
Off — no trading; creator fees accrue to buybacks only.

The leverage cap chosen at registration is a hard ceiling: the engine sizes every trade at min(signal suggestion, strategy range, your cap).

Leverage Risk: Higher leverage amplifies both gains and losses. Positions can be liquidated if the market moves against the position significantly. The protocol includes automated risk management, but losses are possible.

Buybacks

When a perpetual position generates profit, the protocol automatically executes a buyback cycle:

Partial or full profit is withdrawn from the position.
Profit is routed through Uniswap on Robinhood Chain to purchase the creator's token at the best available price.
Purchased tokens are sent to a verifiable burn address, permanently removing them from circulation.

All buyback transactions are recorded on-chain and visible in the Fill dashboard. The burn address is the standard EVM dead address (0x…dEaD) and cannot be recovered.

Getting Started

Registering a token takes five steps on the Launch page:

Pick a launchpad — Pons or LaunchHood — both route creator fees to the engine via a launch-form field.
Peg a stock — pick the Ostium market your token tracks, a direction, a max-leverage cap, and a bot strategy (Conservative / Balanced / Degen / Off).
Name your derivative token.
Deploy on the launchpad — the wizard shows the exact settings for your chosen pad with real screenshots (Pons: Creator wallet · LaunchHood: Reward recipient).
Verify & register — paste the token address (0x…); on-chain verification confirms fees route to the engine.

Once verified, the protocol begins collecting fees and deploying positions automatically. No further action is required.

Token Registration

Registration is a one-time process. The protocol verifies on-chain that the token was launched through the Pons factory and that its creator wallet is the Fill protocol wallet. Pons creator wallets are fixed at launch, so fees cannot be redirected after registration.

Important: The Creator wallet must be set to the protocol wallet at launch time — it cannot be changed afterwards. This protects both the protocol and the token holders.

Fee Configuration

On Pons, set the Creator wallet (Advanced section of the launch form) to the Fill protocol wallet. The full wallet address is displayed in the app's registration wizard and in the site footer. Creator fees accrue pre-graduation on the bonding curve and post-graduation from the locked Uniswap pool.

Architecture

Fill Protocol consists of the following components:

Frontend — Static site deployed on Vercel. Handles token registration UI, dashboard, and documentation.
Backend API — Node.js Express server that handles token registration, verification, and status queries.
Worker Service — Background scheduler that continuously monitors fees, manages perpetual positions, and executes buyback cycles.
Database — Firebase Firestore for storing registered token metadata, position state, and transaction history.
On-Chain — All fee collection, position management, and token burns happen directly on Robinhood Chain.

Smart Contracts

Fill does not deploy its own smart contracts. Instead, it interacts with existing protocols on Robinhood Chain:

Pons — Token creation, bonding curve, and creator fee routing.
Ostium — Stock perpetual position management on Arbitrum (AAPL, TSLA, NVDA, …).
Uniswap V3 — Token swaps for buyback execution.

API Reference

GET /api/v1/tokens/:address

Returns the current status of a registered token, including position data and buyback history.

GET /api/v1/stats

Security

All protocol wallet keys are stored in encrypted environment variables, never in source code.
Creator wallet configuration is verified on-chain before registration is accepted.
Pons creator wallets are immutable after launch, ensuring fee routing cannot be changed post-registration.
The protocol is fully autonomous and on-chain — every fee claim, trade, and buyback is verifiable on the block explorers.
Rate limiting is enforced on all API endpoints to prevent abuse.

Data Collection

Fill Protocol does not collect, store, or process personal identifying information. The Protocol interacts exclusively with public blockchain data (wallet addresses, transaction hashes, on-chain state).

Cookies

The website does not use cookies or tracking scripts. No analytics services are embedded.

Third-Party Services

The Protocol interacts with third-party services including Pons, Ostium, Uniswap, and Robinhood Chain / Arbitrum RPC providers. These services have their own privacy policies and terms of service. The Protocol is not responsible for data handling by third parties.

On-Chain Data

All blockchain transactions are public by nature. Wallet addresses, transaction amounts, and position data are visible to anyone on Robinhood Chain. This is inherent to blockchain technology and not controlled by the Protocol.

Risk Disclosure

Important: Trading perpetual contracts with leverage carries a high degree of risk. You should carefully consider whether such trading is suitable for you in light of your financial condition.

Market Risk

The value of digital assets can be highly volatile. Perpetual positions can experience rapid and substantial losses, especially at high leverage levels. Positions may be liquidated if the market moves against them beyond the maintenance margin.

Smart Contract Risk

The Protocol interacts with third-party smart contracts (Pons, Ostium, Uniswap). These contracts are new and may not have been formally audited. Smart contract vulnerabilities, exploits, or failures could result in partial or total loss of funds.

Protocol Risk

The Fill backend is an off-chain service. Service interruptions, bugs, or infrastructure failures could prevent the protocol from managing positions, claiming fees, or executing buybacks in a timely manner.

Regulatory Risk

The regulatory environment for digital assets and decentralized finance is evolving rapidly. Changes in regulations could affect the Protocol's ability to operate or could impose legal obligations on users.

Liquidity Risk

Buyback operations depend on available liquidity for the creator's token. Low-liquidity tokens may experience high slippage during buyback execution, reducing the effectiveness of the burn mechanism.
