Lighter trading bots
Automate Lighter
Lighter is an order-book exchange for perpetual futures and spot pairs. Circuit agents trade it from your own wallet with the same order types they use on Hyperliquid, so a strategy can run on either venue or compare the two.
Orders agents place
Agents open and reduce perp positions, buy and sell spot pairs such as ETH/USDC, and choose market orders or limits that fill immediately, rest on the book or post only as a maker; resting limits last at most 28 days. Orders size to each market's decimals, and orders below the market minimum or 10 USDC fail before they reach the venue.
Backtest on recorded markets
Circuit replays an agent against recorded Lighter markets without a wallet or onchain writes, so you can compare settings in minutes before a live test.
Cross-venue strategies
Running on both Lighter and Hyperliquid lets agents compare prices and funding for the same asset, for example holding the leg that pays funding on one venue against the leg that receives it on the other.
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.
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.
