HL testnet USDC lives in the spot account, not the perp clearinghouse.
GetBalance() was calling UserState() (perp clearinghouseState), which
returned /usr/bin/bash. Switched to SpotUserState() and parse USDC.total - USDC.hold.
Also cleaned up .gitignore to exclude .env, binary, logs, data/.
- config.json: test_mode=false, ready for sim/testnet trading
- trader.go: auto-stop after 5 real trades, exchange response logging,
Stop()/Start() API, shuttingDown flag for graceful stop
- dashboard.go: POST /api/stop + POST /api/start endpoints,
trading status in SSE stats
- exchange/hyperliquid.go: switch HL WS to testnet endpoint
- exchange/hyperliquid_trade.go: switch REST to testnet endpoint,
support base64 + 32-byte EVM private keys
- main.go: listen on trader.StopCh (graceful, no process exit)
- scanner.go: trim TrackedCoins to only 6 core coins (DOGE/LINK/ONDO/OP/WIF/ARB)
- .gitignore: ignore main binary
