exchange.bulk_orders support for HIP-3 (DEX) markets

[xdmaury]

I have a question regarding exchange.bulk_orders and its compatibility with HIP-3 (DEX) markets.

Does bulk_orders support placing orders for assets that belong to a specific DEX (e.g. coins like cash:AMZN)?

Currently, I'm encountering a KeyError when trying to execute a bulk order with a DEX-prefixed asset:

KeyError: 'cash:AMZN'

From the traceback, it seems the error happens inside info.name_to_asset, likely because the asset is not found in the default meta:

order_request_to_order_wire(order, self.info.name_to_asset(order["coin"]))
...
KeyError: 'cash:AMZN'

1. Does exchange.bulk_orders currently support HIP-3 / DEX markets?
2. If yes, is there a specific way to pass the DEX context when placing orders?
3. If not, is there an alternative method recommended for placing bulk orders on DEX assets?

I don't see a dex input too. Even exchange.order() has no dex input.

Looking at the REST API there is no dex input too.

But maybe it will work out if to add the dex key to the dict?

agent_account: LocalAccount = Account.from_key("0x13e9b3741b86d2XXXXXXXXXXXXX")
exchange: Exchange = Exchange(agent_account, 
                              base_url=constants.MAINNET_API_URL, 
                              account_address=agent_account.address,
                              perp_dexs=["", "xyz", "cash"],)

orders = [
    {
        "dex": "cash",
        "coin": "cash:AMZN",
        "is_buy": True,
        "sz": size,
        "limit_px": limit_px,
        "order_type": {"limit": {"tif": "Ioc"}},
        "reduce_only": False,
    },
]

x = exchange.bulk_orders(orders)
print(x)

Yeah, it works with xyz:GOLD. But there are not all coins on a TESTNET.

Code:

agent_account: LocalAccount = Account.from_key("0x13e9b3741b86d2XXXXXXXXXXXXX")
exchange: Exchange = Exchange(agent_account, 
                              base_url=constants.TESTNET_API_URL, 
                              account_address=agent_account.address,
                              perp_dexs=["", "xyz", "cash"],)

orders = [
    {
        "dex": "xyz",
        "coin": "xyz:GOLD",
        "is_buy": True,
        "sz": 0.06,
        "limit_px": 4600,
        "order_type": {"limit": {"tif": "Ioc"}},
        "reduce_only": False,
    },
]

x = exchange.bulk_orders(orders)
print(x)

It seems the dex input is not required. Final code:

agent_account: LocalAccount = Account.from_key("0x13e9b3741b86d2XXXXXXXXXXXXX")
exchange: Exchange = Exchange(agent_account, 
                              base_url=constants.TESTNET_API_URL, 
                              account_address=agent_account.address,
                              perp_dexs=["", "xyz", "cash"],)

orders = [
    {
        "coin": "xyz:GOLD",
        "is_buy": True,
        "sz": 0.06,
        "limit_px": 4600,
        "order_type": {"limit": {"tif": "Ioc"}},
        "reduce_only": False,
    },
]

x = exchange.bulk_orders(orders)
print(x)
