# associated-evm-key (/docs/query/associated-evm-key)

**Category:** Neurons & registration

## Parameters [#parameters]

| Parameter | Type    | Description                         |
| --------- | ------- | ----------------------------------- |
| `netuid`  | integer | Subnet the neuron is registered on. |
| `uid`     | integer | UID of the neuron on that subnet.   |

## CLI [#cli]

```bash
btcli query associated-evm-key --netuid <integer> --uid <integer> --json
```

## Python [#python]

Namespace method (autocomplete, signature help):

```python
import bittensor as bt

sub = bt.Subtensor()
result = sub.neurons.associated_evm_key(netuid=1, uid=1)
```

Or dispatch by name, as an agent would:

```python
result = sub.read("associated_evm_key", netuid=1, uid=1)
```

Async is the same surface awaited: `async with bt.Subtensor() as client:`.
