Reactr Protocol

FEE-POWERED BUYBACK REACTOR · SOLANA

Overview

Reactr is an autonomous on-chain system that converts idle Pump.fun creator fees into leveraged perpetual positions on Solana. Output from those positions buys back and burns the creator's token, producing continuous deflationary pressure with no action required from the creator or holders.

Core principle: Fees in. Leverage fires. Output buys back and burns. Fully automated, fully on-chain.

How it works

The reactor runs a continuous three-stage loop:

Load the fuel — A creator launches a token on Pump.fun and routes 100% creator fee share to the Reactr core wallet. All trading fees flow to the core.
Insert the rod — Fees are deployed into leveraged perpetual positions based on the creator's chosen market, direction, and leverage.
Core goes critical — When positions profit, gains are harvested, used to buy the creator's token on the open market, and burned to a dead address.

Core engine

The core engine is a background service that watches Solana for incoming fee transfers to registered token wallets. When fees pass a configurable threshold, they are swept and converted to the appropriate collateral for position entry.

Fee distribution

70% — Deployed as perpetual collateral. Profits buy back and burn the fueled token.
30% — Direct $RTR buyback and burn.

Reaction strategy

Each fueled token is assigned a strategy from its registration parameters:

Underlying market — the asset the position tracks (SOL, BTC, ETH, and major Solana assets via Flash).
Direction — LONG only at launch. Shorts are in development.
Leverage — 25x to 250x depending on provider and market.

Leverage risk: Higher leverage amplifies gains and losses. Positions can be liquidated on adverse moves. The core includes automated risk management, but losses are possible.

Buyback & burn

When a position generates profit, the core runs a buyback cycle:

Partial or full profit is withdrawn from the position.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

Every buyback is recorded on-chain and surfaced in the reactor log. The burn address is a standard Solana dead address that cannot be recovered.

Supported markets

Jupiter Perps

Up to 250x leverage: SOL, BTC, ETH.

Flash Trade

Up to 100x leverage on major Solana markets: BONK, WIF, JUP, DOGE, PEPE, JTO, PYTH, RNDR, POPCAT, and more.

Getting started

To fuel a token with Reactr:

Create your token on Pump.fun.
Set 100% creator fee share to the Reactr core wallet (shown in the app).
Open the app and go to Start a Reaction.
Pick your market, direction (LONG), and leverage.
Name your derivative.
Paste your mint address and click Verify.

Once verified, the core begins claiming fees and firing positions automatically. No further action required.

Token registration

Registration is one-time. The core verifies that the Pump.fun fee-sharing config points 100% to the core wallet and that admin authority is revoked (locked), so fees cannot be redirected later.

Important: The fee-sharing config must be locked (admin revoked) before registration succeeds. This protects both the protocol and token holders.

Fee configuration

On Pump.fun, set the creator fee recipient to the Reactr core wallet. The full address is shown in the app's registration wizard and in the site footer. Allocation must be 100% for verification to pass.

Architecture

Reactr consists of:

Frontend — Static site (this app) handling registration, dashboard, and docs.
Core API — Node.js service handling registration, verification, and status queries.
Worker service — Background scheduler monitoring fees, managing positions, and firing buyback cycles.
Database — Stores registered token metadata, position state, and transaction history.
On-chain — Fee collection, position management, and burns all happen on Solana.

Smart contracts

Reactr does not deploy its own programs. It interacts with existing, audited protocols on Solana:

Pump.fun — token creation and fee-sharing configuration.
Jupiter Perps — perpetual positions for SOL, BTC, ETH.
Flash Trade — perpetual positions for major Solana markets.
Jupiter Aggregator — swaps for buyback execution.

API reference

POST /api/v1/tokens/register

{
  "mint": "string — Solana mint address (base58)",
  "underlying": "string — target market symbol (SOL, BTC, …)",
  "side": "string — position direction (long)",
  "leverage": "number — leverage multiplier (25–250)"
}

GET /api/v1/tokens/:mint/status

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

GET /api/v1/stats

Returns aggregate metrics: active reactions, position PnL, supply burned, and buybacks fired.

Security

Core wallet keys live in encrypted environment variables, never in source.
Fee-sharing configs are verified on-chain before registration is accepted.
Admin revocation is required, so fee routing cannot change after registration.
The protocol is open source and reviewable on GitHub.
Rate limiting is enforced on all API endpoints.

Terms of Service

You must be at least 18 and legally permitted to use decentralized financial protocols in your jurisdiction. You are solely responsible for compliance with applicable laws.

2. Nature of service

Reactr is an autonomous, non-custodial system interacting with third-party contracts on Solana. It does not hold or control user funds. All transactions are on-chain and irreversible.

3. No financial advice

Nothing provided by the Protocol is financial, investment, legal, or tax advice. Leveraged trading carries substantial risk of loss.

4. Assumption of risk

You accept the inherent risks of blockchain technology, smart-contract interaction, leveraged trading, and asset volatility, and full responsibility for any losses.

5. No warranties

The Protocol is provided "as is" without warranties of any kind. No guarantee of uptime, accuracy, or profitability.

6. Limitation of liability

In no event shall the developers or contributors be liable for any indirect, incidental, or consequential damages arising from your use of the Protocol.

Privacy Policy

Last updated: June 2026

Reactr does not collect or store personal identifying information. It interacts exclusively with public blockchain data. The website uses no cookies, tracking, or analytics. Third-party services (Pump.fun, Jupiter, Solana RPC) have their own policies. All blockchain transactions are public by nature.

Risk Disclosure

Important: Trading perpetuals with leverage carries a high degree of risk. Consider carefully whether it is suitable for your financial condition.

Market risk — Positions can experience rapid, substantial losses, especially at high leverage, and may be liquidated.

Smart-contract risk — The Protocol interacts with third-party contracts. No audit eliminates all risk.

Protocol risk — The core is an off-chain service. Outages or bugs could prevent timely fee claims, position management, or buybacks.

Liquidity risk — Low-liquidity tokens may suffer high slippage during buybacks, reducing burn effectiveness.
