ActiveReactor Review 2026: AI Trading Agents and Sandbox
Reactor lets users build rule-based or AI-assisted trading agents, test them against live prices with virtual funds, and then send live orders through connected wallets to supported venues. The sandbox and visible decision logs are useful for evaluating a strategy, but they do not remove the risks of live trading.

Our verdict on Reactor
6.5/10Reactor may suit traders who want to turn a rule-based idea into an automated agent and inspect its decisions before committing real funds. Its strongest feature is the live-price sandbox, paired with logged decisions and a stated 14-day proving period. The main caveat is that sandbox results use virtual money and cannot establish how a strategy will perform with live execution. Fees, audits, team details, and regulatory status are not published, so users should investigate those points before connecting a wallet or trading.

What is Reactor?
Reactor is a crypto trading platform for building automated agents and evaluating strategies. Users can describe a strategy in plain language or combine indicators in a visual builder, then run the agent against live prices with virtual money. Reactor says the sandbox starts with $10,000 and agents can qualify for live trading after 14 days.
How Reactor works
Reactor turns a written trading idea into editable signal nodes, or lets users construct a strategy directly in a visual builder. Conditions can be combined with AND or OR logic, and the platform presents agent decisions in a log. Reactor also lists AI models in its gateway, though it does not explain which model is used for each agent or feature.
6 features
Key features
01
Strategy builder
Describe a strategy in a sentence or assemble it from indicator signals. The builder supports combining conditions with AND or OR logic.
02
Live-price sandbox
Agents trade against live prices using virtual funds, with decisions and results recorded. Reactor describes a $10,000 sandbox and a 14-day proving period.
03
AI model gateway
The site lists models from providers including Anthropic, OpenAI, Grok, Qwen, Gemini, DeepSeek, Mistral, and Kimi in its AI Gateway.
04
Public agent records
Published agents can show performance information such as PNL and drawdown, and Reactor says users can follow or copy agents.
05
Live venue trading
Reactor names Hyperliquid, Aster, and Lighter as venues for live orders. Orders are described as leaving from a connected wallet.
06
Cross-chain swap
The platform includes a swap interface for moving funds between chains, with rate, estimated time, and network fee shown before confirmation.
Pros and cons
What we like
- Users can build and explore agents in the sandbox without connecting a wallet.
- Sandbox decisions are logged, making it possible to inspect why an agent acted or waited.
- Strategies can be created from written instructions or assembled from editable signal conditions.
- Published agent pages can show PNL, drawdown, and other performance details.
- The site names multiple venues for live trading rather than limiting users to a single venue.
Watch out for
- A 14-day sandbox record does not establish that a strategy will perform similarly with real funds.
- Fees and the terms of live execution are not published.
- Reactor does not state whether its contracts or trading infrastructure have been audited.
- The project does not identify its team or state its regulatory status.
- Strategies and leaderboard results can change, and past sandbox performance is not a guarantee of future results.
Reactor fees
Reactor does not publish a general fee schedule for agent use or live trading. Venue trading fees and any other costs should be checked before placing an order. The swap interface says it displays the rate, estimated transfer time, and network fee before confirmation, but no fixed fee amounts are published.
Is Reactor safe?
Reactor does not state whether its smart contracts, software, or trading infrastructure have been audited. It also does not publish details about its security controls or identify its team, so users cannot assess those areas from the platform description alone.
Reactor says live orders are sent from a connected wallet, but the precise custody and authorization model is not explained. Live trading carries market and execution risk as well as wallet, venue, and software risks. Sandbox results use virtual funds and should not be treated as evidence of future live performance. Reactor does not state its regulatory status.
6 steps
How to get started with Reactor
- 1
Open Reactor and choose whether to connect a wallet or explore without signing in; the site says strategy building and sandbox use are available without a wallet.
- 2
Create an agent by describing a trading strategy or adding signals to the builder, then review its conditions and logic.
- 3
Run the agent in the sandbox and inspect its logged decisions and performance over time.
- 4
Evaluate the results over the stated 14-day proving period, keeping in mind that sandbox trading uses virtual funds.
- 5
If you choose to trade live, connect a wallet, select a supported venue and market, and review the order details and costs before confirming.
- 6
Publish the agent record or follow another agent if you want to share or copy a strategy.
Who Reactor is for
Reactor is aimed at crypto traders who want to build, observe, or copy automated strategies, particularly those who value a paper-trading period before live execution. It is less suited to users looking for a fully documented fee structure, independently verified security information, or a guaranteed path from sandbox performance to live results.
Reactor FAQs
What is Reactor?
Reactor is a trading platform where users can build agents from strategy instructions or signal nodes. Agents can first trade in a virtual-money sandbox using live prices, then qualify for live trading after 14 days.
How does Reactor's trading sandbox work?
Reactor describes a $10,000 sandbox balance, live market prices, and a 14-day proving period before an agent can graduate to live trading. Sandbox funds are virtual, so the results do not show how a strategy would perform with real capital, fees, or live execution conditions.
Which exchanges does Reactor support?
The platform names Hyperliquid, Aster, and Lighter as venues for orders. Reactor says live orders leave from a connected wallet; check the venue and order details before confirming any trade.
Can I use AI to build a Reactor trading agent?
Reactor says strategies can be built by describing them in a sentence or arranging indicator signals with AND/OR logic. The site also lists AI models in its gateway, but does not publish detailed model pricing or explain which models are required for each feature.
What fees does Reactor charge?
Reactor does not publish a fee schedule. Its swap interface says it displays the exchange rate, estimated time, and network fee before a user confirms a transfer, but live trading and venue costs should be checked before use.
Is Reactor safe to use?
Reactor does not state whether the platform has been audited or provide a public account of its security controls. Live trading involves market, execution, wallet, venue, and software risks; use only funds you can afford to lose.
