# set-subnet-identity (/docs/tx/set-subnet-identity)

Stores the subnet's public profile — name, links, contact, logo — so
explorers and participants can identify it. Owner-only: the signing
coldkey must own the subnet. Everything submitted is public and permanent
history on chain. Calling again overwrites the whole record (empty fields
clear their previous values); the chain enforces length limits on each
field. Purely cosmetic — for the token ticker use `update_symbol`, and
for economics use `set_hyperparameter`.

## Parameters [#parameters]

| Parameter        | Type    | Required | Description                                               |
| ---------------- | ------- | -------- | --------------------------------------------------------- |
| `netuid`         | integer | yes      | Subnet the identity is for; the signer must be its owner. |
| `subnet_name`    | string  | yes      | Display name shown for the subnet.                        |
| `github_repo`    | string  | no       | GitHub repository URL for the subnet's code.              |
| `subnet_contact` | string  | no       | Contact address for the subnet operators.                 |
| `subnet_url`     | string  | no       | Website for the subnet.                                   |
| `discord`        | string  | no       | Discord handle or server invite.                          |
| `description`    | string  | no       | Short free-text description of what the subnet does.      |
| `logo_url`       | string  | no       | Logo image URL for the subnet.                            |
| `additional`     | string  | no       | Any extra free-text information to publish.               |

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

## CLI [#cli]

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

```bash
btcli tx set-subnet-identity \
  --netuid <int> \
  --subnet-name <value> --dry-run
btcli tx set-subnet-identity \
  --netuid <int> \
  --subnet-name <value> -w my_coldkey
```

## Python [#python]

```python
import bittensor as sub
from bittensor.wallet import Wallet

wallet = Wallet(name="my_coldkey", hotkey="my_hotkey")
intent = sub.SetSubnetIdentity(netuid=1, subnet_name="...")

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:

```python
await client.execute_tool("set_subnet_identity", {...}, wallet)
```
