3Commas Review 2026: Crypto Trading Bots, Not Arbitrage

3Commas is one of the best-known names in automated crypto trading. Running since 2017, it has grown into a full bot and portfolio-management platform used by hundreds of thousands of traders, letting you build dollar-cost-averaging, grid and signal bots across major exchanges from a single dashboard. On an arbitrage-focused site, though, the first question is blunt: does 3Commas actually do arbitrage? We went through the vendor’s own pages to answer that honestly rather than assume.

The short version is that 3Commas is a strong, mature automation platform that is not, by its own admission, an arbitrage tool. Its public crypto-arbitrage page states plainly that it does not offer an arbitrage bot and points users to DCA, grid and signal bots instead. That distinction matters for anyone arriving here hoping to exploit price differences between exchanges. This review explains what 3Commas really is, how it works, where it genuinely fits, and the risks worth knowing before you connect an exchange account.

What is 3Commas?

3Commas is a cloud-based crypto trading automation platform operated by 3C Trade Tech Ltd., a British Virgin Islands-registered company that has run the service since 2017. Rather than a desktop program, it is a web and mobile app that connects to your exchange accounts through API keys and places trades on your behalf according to the bots and rules you configure. It is non-custodial in the important sense that your coins never leave the exchange: 3Commas states it cannot withdraw your funds and only trades within the permissions your API key grants. Its headline promise of “cross-exchange automation from a single dashboard” refers to managing several connected exchange accounts and their bots in one place — not to moving money between exchanges to capture price gaps.

Platforms and how it works

3Commas is exchange-neutral and connects to a shortlist of major centralized exchanges. Its current exchange table lists nine officially supported venues — Binance, Bybit, OKX, Bitget, Gate, Kraken, KuCoin, Coinbase and Hyperliquid — covering spot and, on most, futures markets (the site’s metadata references a larger number, but the live table shows nine). You connect each account either through the guided Fast Connect flow or by pasting API keys manually, ideally with IP whitelisting enabled and withdrawal permissions switched off at the exchange. Once connected, you build bots or place manual “smart” trades, and 3Commas executes them around the clock from its own servers, so your own computer does not have to stay switched on.

Key features

• DCA Bot — dollar-cost-averaging strategies with safety and averaging orders, multiple take-profit targets, trailing, stop-loss and futures hedge and “Beast” modes, triggered by built-in indicators or TradingView webhooks.
• Grid Bot — automated buy-low/sell-high across a defined price range, with range-trading, trend-following and scalping modes, trailing up and down, and a backtest simulator.
• Signal Bot — turns TradingView alerts into automated long or short positions, with Smart Trade integration for exits.
• Smart Trade terminal — manual orders with trailing take-profit, trailing stop-loss and multiple take-profit levels on any connected exchange.
• Testing tools — backtesting, a demo/paper-trading account, Pine Script support and webhook execution across plans.
• Management — iOS and Android apps, a multi-account dashboard and, on higher tiers, a read/write developer API.

Does 3Commas do arbitrage?

This is the question that brings most visitors to an arbitrage site, so we will not dance around it: no, 3Commas does not offer a genuine arbitrage bot. Its own crypto-arbitrage page says exactly that and directs readers to the DCA, grid and signal bots instead — even though the same page and parts of the site navigation still use the word “arbitrage,” which is confusing and, frankly, a little misleading. True cross-exchange arbitrage means holding balances on two or more venues, spotting a price gap, buying on the cheaper exchange and selling on the dearer one, then rebalancing funds between them, often in milliseconds. 3Commas does none of that: each bot operates inside a single exchange account at a time, averaging into a position (DCA), working a price grid (grid) or acting on an incoming signal. If your objective is latency or cross-exchange arbitrage, this is simply the wrong category of tool, and you should be looking at dedicated arbitrage scanners and execution software.

Pros and cons

Pricing

3Commas runs on tiered monthly subscriptions rather than a one-time licence. At the time of writing the plans are Starter (around $20 a month, or roughly $15 billed annually), Pro (around $50 a month, roughly $38 annually) and Expert (around $140 a month, roughly $105 annually), with a discount for paying yearly. Starter is spot-only at one exchange with a handful of active bots; Pro adds futures, more API keys and higher bot limits; Expert raises the limits sharply and unlocks the read/write developer API. A free trial is offered on sign-up, and the platform accepts cards, PayPal and several cryptocurrencies, though recurring billing is not available for crypto payments. Because 3Commas revises its tiers periodically, confirm the current prices and limits on the official 3Commas pricing page before subscribing.

Who is it for?

3Commas suits active crypto traders who want to automate dollar-cost-averaging, grid or signal strategies across one or more major exchanges without writing code, and who value backtesting and a polished interface. It is a poor fit for anyone whose actual goal is arbitrage — profiting from price differences between exchanges, or between spot and futures — because that is simply not what the platform does. If you arrived here while researching arbitrage approaches more broadly, our overview of how arbitrage trading changed in 2026 puts automation tools like this in context alongside true arbitrage software.

Limitations and risks

Two risks deserve emphasis. The first is security history: in December 2022, 3Commas confirmed that a large set of users’ exchange API keys had been leaked — reports cited roughly 100,000 keys — after Binance publicly warned users and the company had initially attributed losses to phishing. 3Commas urged affected users to revoke and recreate their keys, and has since promoted Fast Connect, IP whitelisting and tighter key storage. The episode is a reminder that any platform holding your API keys is a target: grant trade-only permissions, disable withdrawals, and whitelist IP addresses at the exchange. The second is category risk: because bots act with your exchange permissions, a misconfigured DCA or grid bot can accumulate losses in a trending market, and exchanges set their own rules on automated trading — always check that your venue permits API bots and the strategy you intend to run. Finally, the operator is an offshore British Virgin Islands entity, and as a software-only provider it offers no brokerage or custody and names no specific financial licence.

Verdict

As a crypto trading-bot platform, 3Commas is one of the more capable and polished options on the market: the DCA, grid and signal bots are genuinely useful, the interface is mature, and the non-custodial API model is sensible. But judged as arbitrage software — the lens of this site — it falls short, because by the vendor’s own admission it has no arbitrage bot at all. Add a notable 2022 security incident and an offshore operator, and the result is a tool we rate 3.7 out of 5: recommendable for automated spot and futures strategies, but the wrong choice if arbitrage is what you are really after. Traders focused on cross-exchange or latency arbitrage should stay with dedicated arbitrage platforms.

Frequently asked questions

Does 3Commas have an arbitrage bot?

No. 3Commas’ own arbitrage page states that it does not offer an arbitrage bot and directs users to its DCA, grid and signal bots instead. It automates trading within a single exchange account rather than exploiting price gaps between exchanges.

Is 3Commas safe to use?

It is non-custodial — your funds stay on the exchange and it cannot withdraw them — but it suffered a confirmed API-key leak in December 2022. To reduce risk, use trade-only API permissions, disable withdrawals, and enable IP whitelisting at your exchange.

How much does 3Commas cost?

Plans are subscription-based, roughly $20 a month (Starter), $50 (Pro) and $140 (Expert) at the time of writing, with a discount for annual billing and a free trial on sign-up. Check the official pricing page for current figures, as the tiers change periodically.

Which exchanges does 3Commas support?

Its current table lists nine major exchanges, including Binance, Bybit, OKX, Bitget, Gate, Kraken, KuCoin, Coinbase and Hyperliquid, across spot and, on most, futures markets.

Is 3Commas good for beginners?

The interface, demo/paper trading and backtesting make it approachable, but automated bots still carry real market risk. Beginners should start small, use the demo account first, and understand each bot before committing capital.
