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

Stores public, human-readable metadata against the signing coldkey so
explorers, wallets, and delegators can recognize it — useful for validator
operators and subnet owners who want a public face. The signing coldkey
must own at least one hotkey registered on some subnet, else the call
fails with `HotKeyNotRegisteredInNetwork`. Everything submitted is
public and permanent history on chain, so include nothing sensitive.
Calling again overwrites the whole identity (empty fields clear their
previous values); the chain enforces length limits on each field. Purely
cosmetic: no effect on balances, stake, or permissions.

## Parameters [#parameters]

| Parameter     | Type   | Required | Description                                             |

| `github_repo` | string | no       | GitHub repository URL.                                  |
| `image`       | string | no       | Avatar or logo image URL.                               |

| `description` | string | no       | Short free-text description of who this key belongs to. |
| `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-identity \
  --name <value> --dry-run
btcli tx set-identity \
  --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.SetIdentity(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_identity", {...}, wallet)
```
