Reward Kit is still in early alpha, and may contain bugs or unexpected behavior.
The Boost V2 Docs are under active development and will be subject to changes.
A React Query mutation hook that handles claiming incentives for a specific boost. This hook manages the blockchain transaction process for claiming boost incentives, including signature verification.

Basic Usage

Here’s a simple example of using the useClaimIncentives hook: 
import { useClaimIncentives } from '@boostxyz/reward-kit-react';

function ClaimButton() {
  // Initialize the hook
  const { mutate, isPending, isSuccess, error } = useClaimIncentives({
    boostId: "11155111:0x378632819F39C74c4F56B1429E760739c5fb51b7:33",
    address: "0x123..." // Connected wallet address
  });

  const handleClaim = () => {
    mutate({
      signature: "0xabc...", // Valid signature from backend
      claimant: "0x123..." // Address of person claiming
    });
  };

  return (
    <div>
      <button
        onClick={handleClaim}
        disabled={isPending}
      >
        {isPending ? 'Claiming...' : 'Claim Boost'}
      </button>

      {isSuccess && <p>Successfully claimed!</p>}
      {error && <p>Error: {error.message}</p>}
    </div>
  );
}

​
Error Handling

The hook includes built-in error handling for common scenarios: 
function ClaimWithErrorHandling() {
  const { mutate, error } = useClaimIncentives({
    boostId: "11155111:0x378632819F39C74c4F56B1429E760739c5fb51b7:33"
  });

  const handleClaim = async () => {
    try {
      await mutate({
        signature: "0xabc...",
        claimant: "0x123..."
      });
    } catch (err) {
      // Handle specific error cases
      if (error?.message.includes("No connected address")) {
        // Handle wallet connection error
      } else if (error?.message.includes("No permission")) {
        // Handle permission error
      }
    }
  };

  return <button onClick={handleClaim}>Claim</button>;
}

Full Implementation

Here’s a more complete example showing how to integrate the hook with loading states and error handling: 
import { useClaimIncentives } from '@boostxyz/reward-kit-react';

function BoostClaimInterface() {
  const {
    mutate,
    isPending,
    isSuccess,
    error
  } = useClaimIncentives({
    boostId: "11155111:0x378632819F39C74c4F56B1429E760739c5fb51b7:33",
    address: "0x123..."
  });

  // Track UI state
  const [showSuccess, setShowSuccess] = useState(false);

  const handleClaim = async () => {
    try {
      // Attempt to claim
      await mutate({
        signature: "0xabc...", // Valid signature
        claimant: "0x123..." // Claimant address
      });

      // Show success message
      setShowSuccess(true);
      setTimeout(() => setShowSuccess(false), 3000);
    } catch (err) {
      console.error('Claim failed:', err);
    }
  };

  return (
    <div>
      <button
        onClick={handleClaim}
        disabled={isPending || isSuccess}
      >
        {isPending ? 'Processing...' : 'Claim Boost'}
      </button>

      {/* Status messages */}
      {isPending && <p>Transaction in progress...</p>}
      {showSuccess && <p>Successfully claimed boost!</p>}
      {error && (
        <div className="error">
          Failed to claim: {error.message}
        </div>
      )}
    </div>
  );
}
The hook integrates with React Query for efficient caching and state management of the claim process. It handles the complete lifecycle of the claim transaction, from simulation to execution on the blockchain.
