# withdraw-crowdloan (/docs/tx/withdraw-crowdloan)

Contributors can pull their contribution back out of any crowdloan that
has not finalized, including while it is still raising. The creator may
only withdraw the part of their contribution above the initial deposit;
the deposit itself stays locked until `dissolve_crowdloan` returns it.
Fails once the crowdloan has finalized or if the signer has nothing left
to withdraw.

| Signer    | Pallet    | Wraps                |
| --------- | --------- | -------------------- |
| `coldkey` | Crowdloan | `Crowdloan.withdraw` |

## Parameters [#parameters]

| Parameter      | Type    | Required | Description                                                |
| -------------- | ------- | -------- | ---------------------------------------------------------- |
| `crowdloan_id` | integer | yes      | Identifier of the crowdloan, assigned when it was created. |

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 withdraw-crowdloan \
  --crowdloan-id <int> --dry-run
btcli tx withdraw-crowdloan \
  --crowdloan-id <int> -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.WithdrawCrowdloan(crowdloan_id=0)

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("withdraw_crowdloan", {...}, wallet)
```
