Transactions

authorize-order

Authorize every economic term of a order through the account's origin.

Supports direct post-quantum owners, proxies, derivatives, and multisigs. This grants relayers the complete specified trade; funds move only on execution. Cancel with the same nonce and complete order to revoke its unfilled part.

Signer	Origin	Pallet	Wraps
`coldkey`	signed account (pallet role may apply)	LimitOrders	`LimitOrders.authorize_order`

Parameters

Parameter	Type	Required	Description
`nonce`	integer	yes	Permanent owner-local u64 order nonce.
`order`	object	yes	Complete V1 or V2 VersionedOrder, including every economic term.
`order_data`	string	no	Optional pinned canonical VersionedOrder SCALE bytes as hex.

Address parameters (--hotkey, --coldkey, --dest, ...) accept a raw ss58 address, an address-book or proxy-book name, or a local wallet/hotkey name.

CLI

Preview with --dry-run (shows fee, effects, and policy result without submitting), then submit:

btcli tx authorize-order \
  --nonce <int> \
  --order '<json>' --dry-run
btcli tx authorize-order \
  --nonce <int> \
  --order '<json>' -w my_coldkey

Python

import bittensor as bt
from bittensor.wallet import Wallet

wallet = Wallet(name="my_coldkey", hotkey="my_hotkey")
intent = bt.AuthorizeOrder(nonce=0, order={...})

sub = bt.Subtensor()
plan = sub.plan(intent, wallet)   # fee, effects, policy — no submission
result = sub.execute(intent, wallet)
if not result.success:
    print(result.error.code, result.error.remediation)

(bt.Subtensor is also the async client — async with bt.Subtensor() as client: — see The client.) Or build the intent by op name, as an agent would:

result = sub.execute_tool("authorize_order", {...}, wallet)
