# Web3 tasks: reward users for wallet activity and on-chain actions

> Connect your claimr campaigns to the blockchain and drive engagement through on-chain actions.

## What are Web3 tasks?

Web3 tasks reward users for performing on-chain actions like connecting wallets, holding tokens, minting NFTs, or completing blockchain transactions. These tasks verify cryptocurrency wallet activity and blockchain interactions automatically.

**Use Web3 tasks to:**

* Verify wallet ownership and encourage wallet connections
* Reward users for holding specific tokens or NFTs
* Track on-chain activity like transactions, swaps, or contract deployments
* Build blockchain-native communities through verified on-chain participation
* Gate access based on wallet balance or transaction history

For detailed information about general task settings, including task header, description, rewards, dependencies, and more, refer to [Task settings](/tasks/task-settings).

To see how your task will appear to users, click **Preview**. This will open a new tab showcasing three different views: desktop, tablet, and mobile. You can toggle between these views to ensure your task looks and functions seamlessly across all devices.

<Note>
  **Pro tip**: Web3 tasks automatically verify on-chain activity, so users can't fake completion. This makes them ideal for gating high-value rewards or building verified Web3 communities.
