go-hyperliquid's NewExchange auto-fetches meta/spotMeta/perpDexs and
panics if any of those API calls fail (NewInfo: panic(err)). The quick
trade flow constructs a probe trader inside POST /api/traders, so any
transient Hyperliquid API hiccup crashed the request with a recovered
panic and a bare 500. Wrap the constructor in initExchangeClient, which
converts the panic into an error that surfaces through the existing
exchange-probe validation path as an honest, retryable message.
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.
go-hyperliquid v0.26.0 crashed at startup with
panic: runtime error: index out of range [479] with length 464
github.com/sonirico/go-hyperliquid.NewInfo (info.go:75)
NewExchange -> NewHyperliquidTrader -> AutoTrader.NewAutoTrader
-> TraderManager.LoadTradersFromStore -> main.main
The library's NewInfo built the spot-asset map by indexing
`spotMeta.Tokens[spotInfo.Tokens[0]]` directly, but Hyperliquid recently
added spot tokens whose Tokens[0] value (a logical token *index*, not an
array position) was larger than the Tokens slice length. With every
restart the backend panicked before the API server bound, so the
frontend's `/api/*` proxy got connection refused on every poll and the
dashboard rendered "全是 error" toasts.
v0.36 fixes the panic by building `tokensByIndex map[int]SpotTokenInfo`
and looking up by logical index instead of position. Adopting v0.36
required two small adaptations to our wrapper:
- trader/hyperliquid/trader.go: NewExchange grew an extra `perpDexs
*MixedArray` argument. Passing `nil` keeps the existing
"auto-fetch on first use" behavior.
- trader/hyperliquid/trader_sync.go: `Info.NameToAsset(coin) int` was
renamed to `Info.CoinToAsset(coin) (int, bool)` with an `ok` flag.
refreshMetaIfNeeded now treats `!ok || assetID == 0` as "needs
refresh" (the same semantic as the old `assetID == 0`).
Verified: backend rebuilds cleanly, container is healthy, all
Hyperliquid traders load, AI cycles execute, and Hyperliquid order
sync receives the full historical trade window.
This PR adds support for Hyperliquid's Unified Account mode where Spot USDC
balance can be used as collateral for Perpetual trading.
Changes:
- Add HyperliquidUnifiedAcct field to Exchange config (default: true)
- Update HyperliquidTrader to support unified account mode
- When enabled, Spot USDC balance is added to available trading balance
- Update API request/response structs for unified account toggle
- Update trader config propagation from exchange config
This aligns with Hyperliquid's roadmap to make Unified Account the default.
Gate.io Integration:
- Add Gate trader with full Trader interface implementation
- Add order_sync.go for background trade synchronization
- Fix quantity display (convert contracts to actual tokens via quanto_multiplier)
- Fix fill price return in OpenLong/OpenShort/CloseLong/CloseShort
- Add Gate-specific CoinAnk K-line data source support
- Add Gate to supported exchanges in frontend and backend
- Add Gate/KuCoin logo SVG icons
Trader Package Refactoring:
- Move exchange-specific code into subdirectories (binance/, bybit/, okx/, bitget/, hyperliquid/, aster/, lighter/, gate/)
- Create types/ package for shared types to avoid circular dependencies
- Move TraderTestSuite to trader/testutil package to avoid import cycles
- Update market.GetWithExchange to support exchange-specific data
