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

Returns contributions (excluding the creator's) to their contributors.
Only the creator may call it. Each call refunds at most 50 contributors,
so large loans may need several `refund_crowdloan` calls before
everyone is paid back. Once all contributors are refunded, the creator
runs `dissolve_crowdloan`, which returns the creator's remaining
contribution (including the deposit) and removes the loan.

## Parameters [#parameters]

| Parameter      | Type    | Required | Description                                                |

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 refund-crowdloan \
  --crowdloan-id <int> --dry-run
btcli tx refund-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.RefundCrowdloan(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("refund_crowdloan", {...}, wallet)
```
