Reactor Review 2026: Trading Agents and Sandbox Testing

Reactor is a trading-agent platform where users build strategies, run them against live prices with virtual funds, and can then connect them to supported trading venues. Its sandbox and public performance records are useful checks, but they do not remove the risks of live, leveraged trading.

Our verdict on Reactor

5.8/10

Reactor may suit crypto traders who want to define strategies, observe how they behave against live prices, and inspect logged decisions before risking real funds. Its strongest feature is the sandbox-to-live workflow, paired with public agent records and a stated 14-day minimum test. The main caveat is that simulated results cannot establish live profitability, while details about fees, audits, custody, and wallet permissions are not published. Treat the sandbox as a testing tool, not a promise of returns.

What is Reactor?

Reactor is a trading-agent platform for building strategies, testing them against live prices, and potentially sending orders to trading venues. Strategies can be described in text or assembled from technical indicators and logical conditions.

New agents run in a virtual-fund sandbox. Reactor says agents need 14 days there before they can graduate to a connected wallet for live trading. Users can publish performance records and follow or copy agents. The homepage lists Hyperliquid, Aster, and Lighter as venues, plus a swap interface that shows Ethereum-to-Arbitrum transfers.

The platform displays a REACT token sale, but does not explain the token's utility in detail. Trading fees, team information, and audits are not published on the homepage.

How Reactor works

Reactor provides a strategy builder for creating trading agents. A user can describe a strategy in a sentence or arrange indicators such as RSI and EMA on a canvas, combining signals with logical conditions. The homepage also lists several AI models in its gateway, but the specific role of each model in a given strategy is not fully explained.

Agents first run in a sandbox using live market prices and virtual money. Reactor says it logs each decision and calculates PNL from fills, and requires at least 14 days in the sandbox before an agent can graduate. Users can publish a performance page, then connect a wallet for live orders on listed venues including Hyperliquid, Aster, and Lighter. Sandbox results are simulated and do not ensure similar execution or returns with real funds.

6 features

Key features

Strategy builder

Create a strategy from a written prompt or place indicator signals on a canvas and connect them with AND or OR conditions.

Live-price sandbox

Agents run against live prices with virtual funds in a stated $10,000 sandbox. Reactor says it logs decisions and uses fills to calculate PNL.

Live trading gate

An agent can graduate to a wallet after 14 days in the sandbox. Live orders are sent through a connected wallet to a supported venue.

Public agent records

Users can publish a page showing performance information such as PNL and drawdown, and other users can follow or copy an agent.

Venues and swaps

The homepage lists Hyperliquid, Aster, and Lighter for trading, and shows a cross-chain swap flow between Ethereum and Arbitrum.

AI model options

The platform names models from providers including Anthropic, OpenAI, Grok, Qwen, Gemini, DeepSeek, Mistral, and Kimi for its AI gateway.

Pros and cons

What we like

Users can test strategies on live prices without putting real funds into the initial sandbox.
The platform says it logs agent decisions and bases PNL on fills, making strategy activity easier to inspect.
A 14-day minimum sandbox period creates a testing stage before live trading.
Users can build strategies from prompts or combine indicators with explicit logical conditions.
Published agent records and follower or copy counts offer a way to compare strategies.

Watch out for

Live trading carries market and leverage risk; the strategy sandbox uses virtual money and cannot establish how a strategy will perform with real funds.
Reactor does not publish trading fees, its team details, or audit information.
The wallet, custody, and permission arrangements for live trading are not explained in detail.
The 14-day sandbox period is a minimum gate, not evidence that an agent will be profitable after graduation.
The sample sandbox leaderboard shows results, but past simulated performance does not guarantee future results.

Reactor fees

Reactor does not publish its trading fees. The swap interface says it shows the rate, estimated time, and network fee before a user confirms a transfer; the homepage displays a sample network fee, which should not be treated as a quote for a live transaction. Trading venue fees and any charges for following or copying agents are not specified.

Is Reactor safe?

Reactor does not publish audit information, and the homepage does not explain its smart-contract design, custody arrangements, or the permissions granted to connected wallets. Live orders use a connected wallet and external trading venues, so users should review transaction prompts and understand the risks associated with those venues. No detailed regulatory or licensing status is published.

Sandbox performance is based on virtual funds and is not a guarantee of live results. Live trading can lose money, and leverage can magnify losses. Only adults 18 or older should use trading services where legally permitted; check the law where you live and trade responsibly.

6 steps

How to get started with Reactor

Open Reactor and explore the app; the homepage says users can build and prove agents without connecting a wallet.
2
Create an agent by describing a strategy or adding indicator signals to the canvas, then connect them with conditions such as AND or OR.
3
Run the agent in the sandbox, where it uses live prices and virtual funds, and review its logged decisions and performance.
4
Keep the agent in the sandbox for at least 14 days before considering graduation to live trading.
5

Who Reactor is for

Reactor is aimed at crypto traders who want to create rules-based agents and evaluate them before connecting a wallet for live orders. It may be useful to people comfortable reviewing indicator logic and managing exchange and leverage risks; it is not a substitute for understanding a strategy or supervising live trades.

Reactor FAQs

What is Reactor?

Reactor lets users create rule-based trading agents and test them in a sandbox using live prices and virtual funds. After at least 14 days, an agent can graduate to live trading through a connected wallet.

How do Reactor trading agents work?

You can describe a strategy in a prompt or assemble it from indicator signals and logic such as AND or OR. Reactor says it records sandbox decisions and calculates performance from fills.

Which exchanges does Reactor support?

The homepage lists Hyperliquid, Aster, and Lighter as venues for orders. Check the current venue and wallet requirements in the app before setting up live trading.

Can Reactor guarantee trading profits?

No. The sandbox uses virtual funds, so its results do not show how an agent will perform with real capital, fees, or live execution conditions. Trading can result in losses, especially when leverage is used.

What are Reactor's fees, and does it have a token?

Reactor shows a token sale and uses the symbol REACT, but does not publish trading fees in the homepage information. The swap screen says it displays the exchange rate, estimated time, and network fee before a transaction is confirmed.

Is Reactor safe to use?

Reactor does not publish audit information or detailed custody and wallet-permission arrangements. Check the app's transaction and permission prompts carefully before connecting a wallet or enabling live trading.
