The trading account could only be funded outside NOFX: no way to move
spot ('main wallet') USDC into the perp trading account, and no deposit
address/QR shown anywhere.
- API: /hyperliquid/account now also returns spot USDC (total/available)
alongside the perp summary; /hyperliquid/submit-exchange accepts a
validated usdClassTransfer action (positive plain amount, boolean
toPerp, Mainnet chain) relayed like the existing approval actions
- Web: new HyperliquidFundsPanel in the exchange config modal with a
deposit tab (wallet address QR + Arbitrum/spot routing notes) and a
transfer tab (spot<->perp, signed by the user's own wallet via EIP-712
UsdClassTransfer — user-signed actions derive the account from the
signature, so the agent key NOFX holds cannot and does not move funds)
- Shared EIP-712/provider helpers extracted from HyperliquidWalletConnect
into lib/hyperliquidWallet.ts
The Hyperliquid wallet-connect flow signs configuration values that
must match what the server expects and what the order placement layer
sends on-chain. The same constants live in four call sites:
- trader/hyperliquid/trader.go (used at order placement)
- api/handler_hyperliquid_wallet.go (returned by the connect endpoint
and validated on submit)
- web/src/components/common/HyperliquidWalletConnect.tsx
(signed by the user during connect)
- trader/hyperliquid/builder_fee_test.go
(pins the trader-side value)
Refresh all four together so the surfaces stay in lockstep.
