# Actions: subnet owner Register, configure and manage a subnet you own with Taostats Actions: registration, owner cut, buybacks, hyperparameters, leases and crowdloans. _Source: https://taostats.io/docs/understanding-taostats/taostats-actions/subnet-owner_ _Last reviewed: 2026-10-28_ Everything a subnet owner signs, from registering the subnet to tuning its hyperparameters, in one place and without btcli. Hyperparameter changes are the owner's main lever on how a subnet registers miners and scores them. [Open Subnet Owner](https://taostats.io/pro/actions/subnet-owner). Most of these are `sudo_set_*` calls in AdminUtils. Despite the name, the chain accepts them from the subnet owner. They are usually rate-limited and closed during the admin freeze window before each epoch. Root-only parameters are not listed. For what each parameter does, see [Subnet parameters](https://taostats.io/docs/concepts/subnets/subnet-parameters); for the owner's role, see [Subnet owner](https://taostats.io/docs/concepts/subnets/subnet-owner). > [!NOTE] > **Paid plan** > > Anyone can open an action, fill it in and review the transaction. Signing and submitting requires a paid Taostats plan. Compare plans on [Billing](https://taostats.io/pro/billing), or see [Plans](https://taostats.io/docs/understanding-taostats/taostats-pro/your-taostats-account#plans). ## Subnet ### [Register a Subnet](https://taostats.io/pro/actions/subnet-owner/register-subnet) Register a new subnet with its identity. The chain locks the current subnet registration cost from your balance. The hotkey becomes the subnet owner hotkey. Registering a subnet locks a large amount of TAO, set by the chain at the time of registration. Check the current cost before you sign. [Taostats Actions: Register a Subnet](https://www.youtube.com/watch?v=CASpyn5ctek) ### [Start Emissions](https://taostats.io/pro/actions/subnet-owner/start-emissions) Start emissions on a subnet you own. [Taostats Actions: Start Emissions](https://www.youtube.com/watch?v=0op7tIQcTxE) ### [Change Owner Hotkey](https://taostats.io/pro/actions/subnet-owner/set-owner-hotkey) Sets the subnet's owner hotkey. The chain allows this once a week per subnet. [Taostats Actions: Change Owner Hotkey](https://www.youtube.com/watch?v=zelQYxTwLjA) ### [Create a Crowdloan-Funded Leased Subnet](https://taostats.io/pro/actions/subnet-owner/create-leased-subnet) Open a crowdloan that registers a leased subnet when it is finalized. The chain only registers a leased subnet as the call a crowdloan runs when it is finalized, so this opens that crowdloan. Contributors receive the emissions share as dividends. Your deposit is committed to the crowdloan, and the subnet is only registered once the crowdloan reaches its cap and you finalize it. [Taostats Actions: Create a Crowdloan-Funded Leased Subnet](https://www.youtube.com/watch?v=JTjs-3MbgtQ) ### [Finalise a Crowdloan](https://taostats.io/pro/actions/subnet-owner/finalize-crowdloan) Finalise a crowdloan you created once it has reached its cap, registering its leased subnet. Only the crowdloan's creator can finalise it, and only once the cap has been raised. Finalising runs the call attached to the crowdloan. Finalising spends the funds raised and cannot be undone. ### [End a Lease](https://taostats.io/pro/actions/subnet-owner/terminate-lease) End a lease after its end block and take ownership of the subnet. Only the lease beneficiary can do this, after the lease's end block. The hotkey must be owned by your coldkey. The subnet is transferred to you and the lease is removed. This cannot be undone. [Taostats Actions: End a Lease](https://www.youtube.com/watch?v=sfkv6ENfDXU) - **[Set Subnet Identity](https://taostats.io/pro/actions/identity/set-subnet-identity)** and **[Update Subnet Symbol](https://taostats.io/pro/actions/identity/update-subnet-symbol)**: see [Identity](https://taostats.io/docs/understanding-taostats/taostats-actions/identity). ## Owner cut and buybacks ### [Owner Cut](https://taostats.io/pro/actions/subnet-owner/set-owner-cut-enabled) Turn the subnet owner cut on or off.

[Taostats Actions: Toggle Owner Cut Auto-Lock](https://www.youtube.com/watch?v=zPTRZw47sFo) ### [Buy and Burn](https://taostats.io/pro/actions/subnet-owner/buy-and-burn) Buy the subnet's alpha with TAO and burn it in one step. The TAO is swapped into the subnet's alpha through the pool and the alpha is burned in the same transaction. The trade is refused if the price moves past your max slippage. The alpha bought is destroyed. You do not receive it and this cannot be undone. [Taostats Actions: Buy and Burn](https://www.youtube.com/watch?v=R1TjoSCMoOY) ### [Set Miner Emission to Burn/Recycle](https://taostats.io/pro/actions/subnet-owner/set-miner-emission-burn-recycle) Route a miner's emissions to be automatically burned or recycled.

Or give a hot key an **Owner** proxy and turn on **Complete as proxy wallet**: see [Proxies](https://taostats.io/docs/understanding-taostats/taostats-actions/proxies#sign-as-a-proxy-wallet).
