A Hyperliquid trading bot that never holds your funds

How bot permissions work on Hyperliquid

Hyperliquid supports agent wallets: a signed approval that authorizes a specific key to trade on your behalf. The approval is scoped to trading actions, so withdrawal and transfer remain exclusively signable by your own wallet.

That single design choice removes the largest historical failure mode of crypto trading bots — the operator holding customer funds. If a bot asks you to deposit, the risk you are taking is counterparty risk, not strategy risk.

• Agent approval = trade permission, not custody.
• Withdrawals stay signable only by your wallet.
• Approvals can be revoked on-chain at any time.

What this bot automates

HyperMirror continuously scores public Hyperliquid traders, selects those clearing every quality floor, allocates your capital by score, and mirrors their positions in isolated sub-accounts under hard risk limits.

It also handles the unglamorous parts: rebalancing when weights drift, de-allocating decaying leaders on probation, and replacing a leader immediately when a hard risk breach occurs rather than waiting for the next cycle.

Risk controls the bot enforces

Automation without limits just executes bad decisions faster. Every mirrored strategy runs against a notional ceiling and a leverage cap that is independent of what the leader chooses to use.

• Per-trader notional ceilings so no leader dominates the book.
• Leverage caps applied independently of the leader's own leverage.
• Sub-account isolation so leaders cannot net each other out.
• Score floors, probation and emergency replacement.

Bot versus manual trading

Manual copying fails on latency and discipline: you sleep, the leader does not. A bot mirrors continuously, sizes consistently and does not renegotiate its own rules mid-drawdown.

What a bot cannot do is manufacture edge. It can only execute a selection and sizing policy faithfully — which is why the selection and sizing policy is the product, not the execution loop.
