You've probably seen the words "Voucher" and "GasPass" in D'CENT's announcements, on the Kaia Super Earn campaign page, or in your email inbox. Both are rewards that D'CENT is currently distributing through active campaigns — but they're actually two different kinds of coupons.
In short: GasPass is a credit you spend on gas fees, while a Voucher is real crypto deposited in your wallet. Here's what each is, who gets them, and how to claim both.
⚡ What's the Difference?
Put simply, GasPass is a "gas-fee-only credit" that sits inside your wallet. When you hold this credit, you don't need to keep native coins on hand to cover the network fees for sending tokens or running swaps. Once you register it in the app, it's automatically deducted from eligible transactions on supported networks.
GasPass supported networks: Ethereum Base Solana Kaia
A Voucher (also labeled "Reward" in campaign emails), on the other hand, is a coupon that deposits actual crypto (like USDT) directly into your D'CENT wallet. Once you receive it, you're free to hold it, send it, swap it, or withdraw it however you like.
| GasPass | Voucher / Reward | |
| What you get | Gas-fee credit balance | Real crypto (e.g., USDT) |
| Use restriction | Gas fees only | None — full freedom |
| Analogy | Gas-station prepaid card | Cash |
| How you receive it | In-app quest completion or email QR code | In-app quest completion or email QR code |
If gas fees are a new concept to you, our beginner-friendly guide on what gas fees are and how to reduce them walks through the basics first. For a deeper dive into how GasPass actually works inside the wallet — supported networks, automatic fee handling, sending and swap flows — see our original guide: Introducing GasPass: Enjoy Gas Free Ecosystem in D'CENT Wallet.
🎁 Who Can Get a GasPass or Voucher?
D'CENT is currently distributing GasPass and Voucher through active campaigns. To get either one, just participate in whichever campaign is running at the time.
How you participate depends on the campaign. Some require a wallet purchase during a specific window. Others ask you to complete in-app quests. Always check the official campaign page for the exact rules of whichever campaign is currently running.

🔥 Right Now: Kaia Super Earn Campaign
The most direct way to receive both coupons in a single round is the Kaia Super Earn campaign — running right now until April 14, 2026. Rewards are paid out on the Kaia network, an EVM-compatible Layer 1 blockchain run by the Kaia Foundation.

🔑 How to Register Each Coupon
Both coupons follow the same 3-step pattern: receive the email → scan the QR in the D'CENT App → confirm. But the email you receive and the confirmation screen are different for each. Here's each flow in order.
🎁 Voucher / Reward — 3 Steps
1
Receive the Voucher email. The subject line is "You've Unlocked a Crypto Reward with Your D'CENT Wallet" and it explains that your $25 USDT reward is waiting.
2
Scan the QR code inside the D'CENT App. Open the in-app scanner and point it at the QR code in the email. Must be done within 17 days of receiving the email.
3
Confirm "Coin Voucher Registered!" Once the popup appears, you're done. Your USDT will be airdropped to your D'CENT wallet on May 6, 2026.
⛽ GasPass — 3 Steps
1
Receive the GasPass email. The subject line is "Your GasPass Coupon is Ready!" and it includes your coupon details, supported networks (Ethereum · Base · Solana · Kaia), and the coupon expiration date.
2
Scan the QR code inside the D'CENT App. Open the GasPass menu → tap Register Coupon → scan the QR code from the email (or enter the code manually). Must be done before the coupon's expiration date.
3
See your GasPass balance update. The credit appears on your GasPass screen immediately (in the example above, from $20 → $35). After that, it's automatically deducted on supported-network transactions — no extra steps.
❓ Frequently Asked Questions
Q1: If I buy a D'CENT Biometric Wallet, do I automatically get a GasPass or Voucher?
No. Buying a wallet does not, on its own, qualify you for either coupon. To receive either, you need to participate in an active campaign. The Kaia Super Earn campaign is running right now and distributes both — see the campaign details above for exactly how to qualify.
Q2: My campaign reward hasn't arrived yet. What should I do?
Some rewards require a verification step that takes time. First, check the airdrop date for the campaign you joined: Event 1 of Kaia Super Earn airdrops on May 6, 2026, so anything before that date is still on schedule. Event 2 airdrops within 14 days after the campaign closes. If the airdrop date has passed and you still don't see the reward, contact D'CENT support and provide your D'CENT wallet address.
Q3: I didn't receive the email with my Voucher QR code. Where is it?
Check your spam folder. Verify the email address used at checkout has no typos. Confirm your order was fulfilled — the email is sent only after fulfillment, not at checkout. If none of those resolve it, reach out to D'CENT support with your order number, full name, and shipping address.
Q4: What happens if I don't register the Voucher within 17 days?
Per the Kaia Super Earn campaign rules, the Voucher QR code must be activated inside the D'CENT App within 17 calendar days from the email date — otherwise it becomes void. Once void, the airdrop will not be processed for that entry. If your window is closing, register first and verify the airdrop happens on schedule.
Q5: How is a Voucher different from a regular crypto airdrop?
A regular airdrop is sent directly to a wallet address with no action required from the recipient. A Voucher requires you to receive a QR code by email and actively register it inside the D'CENT App during a limited window. This step lets D'CENT verify the eligible user is the one claiming the reward — and it gives you control over which campaigns you opt into. For other ongoing reward and airdrop events, see our Mega Airdrop Event Application Guide. For technical details on how rewards are settled on Kaia, see the Kaia Developer Docs.
Q6: Can I receive both a GasPass and a Voucher from the same campaign?
Yes. Kaia Super Earn is the clearest example: both Event 1 (Wallet Purchase Cashback) and Event 2 (Kaia Quest) include a Voucher reward and a GasPass bonus. Other campaigns may distribute one or the other depending on their structure — always check the official campaign page for exact terms.
