mint-gamma-with-stake

Mint gamma by burning your stake into your deposit at an API-key hotkey.

Burns up to amount_alpha (all for the whole stake) of your stake on origin_hotkey_ss58 and credits its value in gamma to the deposit at hotkey_ss58, valued as mint_gamma values bought alpha. The stake is destroyed, not moved. spender_ss58, service_hotkey_ss58 and daily_spend_cap_gamma name the deposit's spender and cap as for mint_gamma. Fails rather than minting less than the current quote less rate_tolerance. Its plan's preview and result's data["minted"] are as for mint_gamma.

Parameters

Parameter	Type	Required	Description
`netuid`	integer	yes	Subnet of the stake burned.
`hotkey_ss58`	string	yes	Hotkey of the deposit credited: an API key, not a staking hotkey.
`amount_alpha`	number \| `"all"`	yes	Alpha of stake burned.
`origin_hotkey_ss58`	string	yes	Hotkey the stake is held on (the validator backing the position).
`rate_tolerance`	number	no	Maximum fall of the minted gamma below the quote, as a fraction (0.05 = 5%).
`spender_ss58`	string	no	The account that spends the deposit. A new deposit opens with it, and an existing one must already name it. Omit to keep the deposit's spender, which for a new deposit is the spender of the subnet owner's service, otherwise the subnet owner, or its lease's beneficiary while a lease owns the subnet.
`service_hotkey_ss58`	string	no	Hotkey of a service published on the subnet, instead of a spender. The deposit names the spender the service publishes.
`daily_spend_cap_gamma`	number	no	The deposit's daily spend cap, in gamma; 0 pauses it. A new deposit opens with it, and an existing one must already have it. Omit to keep the deposit's cap, which for a new deposit is none.

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 mint-gamma-with-stake \
  --netuid <int> \
  --hotkey <ss58|name> \
  --amount-alpha <amount|all> \
  --origin-hotkey <ss58|name> --dry-run
btcli tx mint-gamma-with-stake \
  --netuid <int> \
  --hotkey <ss58|name> \
  --amount-alpha <amount|all> \
  --origin-hotkey <ss58|name> -w my_coldkey

Python

import bittensor as bt
from bittensor.wallet import Wallet

wallet = Wallet(name="my_coldkey", hotkey="my_hotkey")
intent = bt.MintGammaWithStake(netuid=1, hotkey_ss58="5F...", amount_alpha=1.0, origin_hotkey_ss58="5F...origin")

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("mint_gamma_with_stake", {...}, wallet)
