Build a crypto trading bot without code
Describe it, don't code it
Open Terminal in Circuit and describe the strategy the way you would explain it to a trader: what to watch, when to enter, how much to risk and when to exit. The Builder turns that into an agent, writes its code, verifies it, and shows progress on the agent's card. To change it later, name the agent and say what to change; successful changes apply to every session from its next run.
Write a spec the Builder can follow
Good specs name the market and venue, the signal with exact numbers, the position size as a share of the agent's capital, the exit rules, how often to check, and which settings should be adjustable. For example: watch BTC, ETH and SOL perps on Hyperliquid using RSI(14) on five-minute candles, go long below 30 and short above 70, risk 25% of my capital per trade, take profit at 3% and stop at 2%, check every five minutes.
Review, backtest and test
With an agent open, /review reports risks and gaps without changing code, Backtest replays it on recorded Hyperliquid or Lighter markets, and Test runs it. Every agent then starts in paper trading on live markets with simulated funds, so you see real behavior before any money moves.
Start from a proven spec
Not sure where to begin? The strategies page has ready specs for copy trading, grids, ETH/BTC pairs, funding shorts, RSI, breakouts, momentum, dip buying and weekly accumulation, each one click away from the Builder.
Self-custodial by design
Agents run on a wallet you create in Circuit or import from Phantom, Rabby or MetaMask. Agents never see private keys: they request typed actions through Circuit's SDK, and Circuit signs outside the agent's sandbox only under a permit you sign with your passkey. Pause, resume or stop any agent at any time; stopping leaves your positions in your wallet.
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.
Getting started
Sign in to app.circuit.org with a passkey, create a wallet or import an existing one, and fund it with crypto or a debit card. Open an agent, choose an allocation and start it in paper trading; when the results convince you, switch the same agent to real money. Pause, resume, top up or stop it any time from your home screen.
