Exchange Passthrough

Forward a pre-signed action directly to HyperLiquid’s /exchange endpoint. Use this when you handle EIP-712 signing yourself and just need hypernode to proxy the request. No authentication required. The payload is forwarded as-is.

Example

curl -X POST https://hyper.polynode.dev/exchange/raw \
  -H "Content-Type: application/json" \
  -d '{
    "action": { "type": "order", ... },
    "nonce": 1234567890,
    "signature": { "r": "0x...", "s": "0x...", "v": 27 },
    "vaultAddress": null
  }'
