Execution

Real fills. You hold the keys.

The governed verdict closes the loop into rented execution — without renting your custody. Perps on Hyperliquid, spot on CoW, both non-custodial.

Hyperliquid — perps
  • BTC/USD and ETH/USD, long/short with leverage, capped at the governor's max.
  • You approve an agent (API) wallet on your own account — it trades, it cannot withdraw.
  • Native TP/SL trigger orders with OCO grouping; you sign the L1 action client-side.
CoW Protocol — spot
  • cbBTC and WETH vs USDC — MEV-protected, gasless settlement via CoW solvers.
  • EIP-712 order signed by your wallet, receiver hard-set to your address.
  • No agent wallet needed — your wallet signs directly on mainnet.

The governor is a gate — not an unbreakable wall.

Enforced by default. With the gate on, a closed verdict greys out the deploy button. Only ALLOW and RESIZE intents reach execution — and a resize ships the capped size, never more.

Override is yours. It's your wallet, your signature, your liability — so you can turn the gate off. Override takes an explicit acknowledgement and shows a persistent banner while it's off.

Both are logged. Enforced and override fires are tagged and tracked. That counterfactual is exactly how the benchmark proves what the gate adds — agency for you, a measurably-additive governor for the record.

Fees

Usage-based. No subscription, no wall.

Hyperhelm bills the execution edge, not the looking. Viewing the governed verdict is free; a small, transparent fee is charged only when a trade actually executes — collected by the venue, shown in the ticket.

Hyperliquid (perps)~1–2.5 bps
Builder code

A small fee in basis points of notional, approved once by you up to a cap. The venue deposits it automatically at fill — no invoice, no signup.

CoW Protocol (spot)modest, capped
Partner fee

A modest partner fee carried in the order's app data. CoW collects and routes it on settlement — gasless, non-custodial.

Shown transparently in the deploy ticket before you sign. You bill for the value created — the governed trade — not for reading the verdict.

Rollout

Mainnet execution launches behind a flag, an allowlist and small size caps, then graduates — after a security review of the order path, the receiver-is-you invariant, and a max-notional kill switch. The cockpit is live to view and connect today; turning on real fills is a deliberate, staged step.

Non-custodial by design

Your keys. Your funds. Your signature.

Handling real money publicly only works one way: never custody it. Hyperhelm holds nothing — every order is signed by you.

We never hold your keys or funds

Hyperhelm is bring-your-own-wallet. You connect, you sign every order client-side, and the backend never touches a private key. Non-custodial is the single biggest de-risk for handling real money.

Agent wallet can trade, never withdraw

On Hyperliquid you approve an agent (API) wallet scoped to your own account. It can place orders but cannot withdraw or transfer — that boundary is enforced on-chain, not by us.

Receiver is always your address

Every CoW spot order is built with the receiver hard-set to your wallet. Funds can only ever settle back to you — it is a structural invariant, not a setting.
