# Fund a campaign

Support a campaign via tiers or a custom amount, and receive an NFT receipt.

You can fund a campaign using a reward tier or a custom amount. Both paths mint an NFT receipt & Perks (if available)

### Before you start

* Connect your wallet.
* Ensure you have $**CAMP Tokens** for the contribution and gas.
* Verify you are on **Camp Network**.

{% hint style="warning" %}
Only fund campaigns from links you can verify. Prefer links shared by the creator’s official accounts.
{% endhint %}

### Option A: fund via a tier

1. Open a campaign.
2. Choose a tier.
3. Click **Support this tier**.
4. Confirm the transaction in your wallet.

### Option B: fund a custom amount

1. Open a campaign with custom funding enabled.
2. Enter a $CAMP amount.
3. Click **Support with custom amount**.
4. Confirm the transaction in your wallet.

### What happens on-chain

After a successful contribution:

* $CAMP moves to the campaign contract.
* Your contribution is recorded.
* Tier counters update.
* You can mint an ERC-721 receipt NFT.
* If your tier includes perks, you may be prompted for fulfillment details.

See [Supporters Perks](/documentation/creator-vault/campaigns/supporters-perks.md) for receipt NFTs and perk fulfillment (physical + digital).

### Common questions

**Can I contribute multiple times?**

You can usually fund multiple times. Receipt minting is still limited to one per tier (or custom funding) per campaign, per wallet.

**What if my transaction fails?**

* Make sure you have enough CAMP for gas.
* Retry with a higher gas setting if your wallet supports it.
* If the campaign ended, funding may be blocked by the contract.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://creator-vault.gitbook.io/documentation/creator-vault/campaigns/fund-a-campaign.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
