create-pure-proxy

Create a pure proxy: a fresh keyless account controlled via delegation.

The chain derives a new address from the signer, proxy_type, index, and the creation block. Nobody holds its private key — the spawner controls it purely through the proxy relationship, which makes it useful as a disposable or role-scoped account (e.g. a Staking-only treasury). Record the creation block and extrinsic index (shown in the result): kill_pure_proxy needs them to close the account later. Losing the spawner key means losing the pure proxy and anything it holds.

Signer	Pallet	Wraps
`coldkey`	Proxy	`Proxy.create_pure`

Parameters

Parameter	Type	Required	Description
`proxy_type`	string	no	Scope of calls the delegation covers. One of: Any, Owner, NonCritical, NonTransfer, Senate, NonFungible, Triumvirate, Governance, Staking, Registration, Transfer, SmallTransfer, RootWeights, ChildKeys, SudoUncheckedSetCode, SwapHotkey, SubnetLeaseBeneficiary, RootClaim. Triumvirate, Senate, Governance, and RootWeights are deprecated on the current runtime: they deny all calls, so a proxy of those types can dispatch nothing. Prefer the narrowest type that covers your use; Any can do everything the account can, including transfers.
`delay`	integer	no	Announcement delay in blocks: the delegate must announce each call and wait this long before executing it, giving you time to veto. 0 executes immediately.
`index`	integer	no	Disambiguator so one signer can create several pure proxies in one block; also part of the derived address. Keep 0 unless batching.

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 create-pure-proxy --dry-run
btcli tx create-pure-proxy -w my_coldkey

Python

import bittensor as sub
from bittensor.wallet import Wallet

wallet = Wallet(name="my_coldkey", hotkey="my_hotkey")
intent = sub.CreatePureProxy()

async with sub.Client("finney") as client:
    plan = await client.plan(intent, wallet)   # fee, effects, policy — no submission
    result = await client.execute(intent, wallet)
    if not result.success:
        print(result.error.code, result.error.remediation)

Or build it by op name, as an agent would:

await client.execute_tool("create_pure_proxy", {...}, wallet)
