Add Reward Claiming Feature/functionality to User Dashboard

[JamesVictor-O]

Description:

Allow users to claim their available rewards by calling the Submission.claimRewards function. Provide feedback on transaction success or failure and update the dashboard after claiming.

Tasks:

• Add a "Claim Rewards" button to the user dashboard.

• Check getClaimableRewards(userAddress) to ensure rewards are available before enabling the button.

• Call claimRewards() using DCUContracts(Networks.ARBITRUM_SEPOLIA).Submission.connect(signer).

• Handle transaction confirmation and display the transaction hash.

• Catch errors (e.g., SUBMISSION__NoRewardsAvailable) and show user-friendly messages.

• Refresh claimable rewards and submission statuses after a successful claim.

Acceptance Criteria:

• "Claim Rewards" button is enabled only when rewards are available.

• claimRewards is called successfully, and the transaction is confirmed.

• Errors are caught and displayed (e.g., "No rewards available").

• Dashboard updates to reflect claimed rewards (zero balance, updated submission status).

• Type-safe interactions are used via @decleanup/contracts.

Note

note the integration is done using type-chain, here is the docs to the type-chain Docs

Hi Reviewer,

I’d like to work on implementing the "Claim Rewards" feature. Here’s how I’ll approach it:

1. Add Button: Add a "Claim Rewards" button to the dashboard, enabled only when rewards are available.
2. Check Rewards: Use getClaimableRewards(userAddress) to verify available rewards.
3. Call claimRewards: Implement claimRewards() using DCUContracts(Networks.ARBITRUM_SEPOLIA).Submission.connect(signer).
4. Transaction Feedback: Show transaction hash on success, and catch errors like "No rewards available" with user-friendly messages.
5. Dashboard Update: Refresh the dashboard after a successful claim, updating the rewards and submission status.

I’ll use type-safe interactions with @decleanup/contracts and TypeChain as per the documentation.

Looking forward to contributing!
