A single-symbol QNT-USDC trader produced 0 candidate coins, 500 errors
from Hyperliquid, and "🚫 Dropped AI decision" warnings — the agent had
no market data to reason about, so it sat in `wait` forever. Three
chained bugs:
1. provider/hyperliquid/kline.go (IsXYZAsset / FormatCoinForAPI):
asset detection required the base symbol to appear in the hardcoded
StockPerpsSymbols / XYZOtherSymbols / display-alias lists. QNT, ARM,
and every other newly-listed Hyperliquid USDC perp wasn't in the
list, so the code routed them to the crypto path (CoinAnk) which
doesn't have them. Now the `-USDC` suffix and `xyz:` prefix are
trusted as definitive Hyperliquid signals — these tokens are
Hyperliquid-specific and new listings don't require a code change.
The hardcoded lists are kept as fallbacks for bare base symbols.
2. market/data_klines.go (getKlinesFromHyperliquid): the function
stripped the `xyz:` prefix before calling GetCandles, defeating
GetCandles's own FormatCoinForAPI logic. With the hardcoded list
missing the new ticker, FormatCoinForAPI couldn't re-add the prefix
and the request hit Hyperliquid's crypto perp endpoint — which
returns 500 for stock-only tickers. Pass the symbol through as-is.
3. trader/auto_trader_loop.go (filterDecisionsToStrategyUniverse): the
AI sometimes echoes a candidate as "QNTUSDC" / "QNT-USDC" / "QNTUSDT"
/ bare "QNT" instead of the canonical "xyz:QNT" we supplied. Strict
exact-match was dropping all of them. Added a base-level key
(strips xyz:, -USDC, -USDT, USDC, USDT, USD; normalizes display
aliases like ROBINHOOD → HOOD) and rewrites the matched decision's
symbol to the canonical form so the order pipeline downstream sees
the format it expects.
After this, a single-symbol stock trader fetches real K-line data from
Hyperliquid, the AI sees real candidates, and decisions get executed
on-chain instead of silently filtered.
- Add Hyperliquid/XYZ symbol normalization tests and backend coverage
- Extend kline and market data lookup paths for US stock symbols
- Wire frontend data API types for stock-oriented market requests
When CLAW402_WALLET_KEY env var is set, all nofxos.ai data API calls
(AI500, OI rankings, NetFlow, price rankings) are automatically routed
through claw402.ai with x402 USDC micropayment.
- provider/nofxos/claw402.go: x402 GET request client for data APIs
- provider/nofxos/client.go: claw402 mode support in doRequest()
- kernel/engine.go: auto-detect CLAW402_WALLET_KEY and enable routing
- mcp/payment/x402.go: MakeClaw402SignFunc helper
Without CLAW402_WALLET_KEY, falls back to direct nofxos.ai (backward compat).
Add two new coin source options for Hyperliquid trading:
- hyper_all: All available Hyperliquid perpetual coins (229 coins)
- hyper_main: Top N coins by 24h volume (default 20)
Changes:
- Add CoinSourceConfig fields: UseHyperAll, UseHyperMain, HyperMainLimit
- Add provider/hyperliquid/coins.go with caching (24h) and volume-based sorting
- Add source types 'hyper_all' and 'hyper_main' to GetCandidateCoins()
- Support mixing with other sources in 'mixed' mode
- Add source tag formatting for UI display
This ensures traders using Hyperliquid can select coins that are actually
available on the exchange, avoiding 'symbol not found' errors.
- Add server time synchronization for KuCoin API to fix timestamp error (400002)
- Return empty list instead of error when no available coins (ai500.go)
