3Commas alternative
3Commas in brief
3Commas is a cloud platform for preset trading bots such as DCA, grid and signal bots. You connect it to centralized exchange accounts with API keys, and the bots trade inside those exchange accounts.
How Circuit differs
Circuit agents trade onchain venues such as Hyperliquid, Polymarket, Lighter and Papertrade, swap across EVM networks and Solana, and also trade Kraken. Funds stay in your own wallet rather than an exchange account, and every signature requires a permit you sign with your passkey. Agents are code, so a strategy is not limited to a preset template: describe it in plain English and the Builder writes it.
When 3Commas fits better
If your money lives on centralized exchanges Circuit does not support and a preset grid or DCA template covers your strategy, an exchange-connected bot is the simpler choice.
Test before you risk money
Every agent starts in paper trading: simulated funds on live markets, with no real money moving. Hyperliquid, Lighter and Kraken orders fill against the live order book and one-minute bars with each venue's fees, funding and liquidation rules, and Polymarket orders fill against the live book. Switch to real money when the results convince you.

Questions to ask any agentic trading platform
Who holds the keys, and can the agent ever see them? Does every trade need your approval, or can approvals be switched off? Can you read the exact code or rules the agent runs, and test them on past and live markets before real money moves? Which markets can it reach: stocks only, one exchange, or onchain venues across networks? And can you stop it instantly without losing control of open positions?
What it costs
Circuit charges no fees today. You pay the venue's trading fees, network gas and any bridge or routing fees, and each prepared action's review shows the costs it reports before you confirm. Today's terms make no commitment about future fees.
