One of the biggest barriers to reward adoption is user friction. Players should not need extra setup to receive earned rewards. Here is how we solved it.

The Challenge

Legacy reward stacks often required extra identity and payout steps before rewards were usable. This created friction and drop-off.

Our Solution

We use server-side receipt verification, deterministic reward ledgers, and secure payout services to keep reward delivery fast and reliable.

Architecture Overview

  1. Ad Completion: Player watches a rewarded ad
  2. Receipt Generation: Ad network provides cryptographic proof
  3. Server Verification: Our backend verifies the receipt authenticity
  4. Ledger Write: Reward is committed to player account balance
  5. Credit Available: XP/STACKS becomes immediately available in-game

Security Considerations

The receipt verification is crucial. We use a multi-step verification process:

// Simplified verification flow
const isValid = await verifyAdReceipt({
  receiptId: receipt.id,
  signature: receipt.signature,
  adNetwork: receipt.network,
  timestamp: receipt.timestamp
});

if (isValid && !isReplay(receipt.id)) {
  await creditReward(player.id, REWARD_AMOUNT);
}

Results

Since implementing gasless rewards:

  • Reward claim rate increased 340%
  • User complaints about "fees" dropped to zero
  • Average session length increased 28%

Low-friction rewards are the future. Learn more about integrating this flow in our SDK documentation.
