Hyperliquid copy trading bot
The strategy
Let me set the public wallet to follow. Check its perp positions every five minutes and mirror increases, reductions and direction changes in proportion to its account equity and my assigned USDC. Cap combined position value at my allocation and any one coin at 25% of it. Close a copied position if it moves 5% against my entry, and do not reopen it until the source trader closes and opens a new position. Finish closing before reversing direction. Stop opening positions if the source account cannot be read. Make the wallet, scaling factor, caps and stop adjustable.
Build it in one click
Start from this exact spec: "Build an agent to copy a Hyperliquid trader". 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.
