Funding rate short bot
The strategy
Watch BTC, ETH, SOL and HYPE perps on Hyperliquid and read each coin's current hourly funding rate. When a coin's funding rate stays above 0.03% per hour for three consecutive hours, open a short with position value equal to 15% of my assigned USDC, one position per coin. Close when funding falls below 0.01% per hour, at a 4% adverse move from entry, or after 48 hours, whichever comes first. Wait for funding to reset below the threshold before shorting that coin again. Check every hour. Make the coins, funding thresholds, size and exits adjustable.
Build it in one click
Start from this exact spec: "Build an agent to short overcrowded perps". Circuit's Builder turns it into an agent, checks the code, and lets you backtest it on recorded markets and paper trade it on live markets before any real money moves. Every number in the spec is a setting you can change.
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.
