Rewards are one of the most powerful growth tools in crypto — and the easiest to exploit.
Across the ecosystem, teams run into the same issues:
Bots and multi-wallet users frequently drain reward pools
Gated access leaks almost instantly
The problem isn’t incentives themselves. It’s identity.
Wallets don’t prove uniqueness.
Anyone can create unlimited wallets and interact repeatedly. Without stronger identity signals, it’s nearly impossible to reward real users, prevent abuse, or build meaningful reputation.
Base Verify is anti-Sybil verification infrastructure built into the Base App and now available to the broader ecosystem.
It allows users to prove ownership of real accounts — such as X, Instagram, TikTok, or Coinbase — without revealing credentials or personal data to applications.
Instead of tying access and rewards to wallets alone, Base Verify anchors them to real-world identity signals and returns a deterministic verification token:
The User proves they own a real account. They log in to a social platform—X, Instagram, TikTok, or Coinbase—through a familiar "Sign in with..." flow, the same kind used by countless apps.
Base Verify creates a unique identifier. This identifier is tied to the user's social account, not their wallet. Critically, the same social account always produces the same identifier.

Base Verify creates a unique identifier. This identifier is tied to the user's social account, not their wallet. Critically, the same social account always produces the same identifier.
Your app stores that identifier. The next time anyone tries to claim—even from a different wallet—you check if you've seen their identifier before.
This creates a simple and powerful guarantee:
One real account equals one claim — regardless of how many wallets a user controls.
It also unlocks something wallets can’t: the ability to recognize high-value users even when their on-chain activity is minimal. A brand-new wallet might still belong to a Coinbase One subscriber, an X Blue user, or a creator with a large audience. Beyond proving uniqueness, Base Verify can also check whether users meet specific requirements—like having 10,000 followers, holding a Coinbase One subscription, or being a verified creator. Users prove they qualify without revealing the underlying data.
Base Verify already powers identity, reputation, and feed quality inside the Base App. We built it to operate at platform scale first, then opened it to all builders.
For the ecosystem, this means you get access to the same infrastructure we rely on. And because verifications are shared across the Base App, users only need to verify once. That single verification then works across every app that uses Base Verify.
Users verify once, and that verification can unlock value across multiple Mini Apps inside the Base App.
Base Verify is already live and operating at scale:
200,000+ verifications completed and growing
It’s already used in production by Base Mini Apps today. Early partners include:
Cody Uses Base Verify to prevent reward farming and enforce one claim per real account.
Scratch Distributes tokens to high-value users instead of anonymous wallets.
Bracket Gates $BRACKY airdrops to Coinbase One members, powering sports betting incentives inside a Mini App.
Rewards that can't be farmed: Ensure incentives go to real people, not wallet farms.
Tiered access using social proof: Unlock Mini App features based on signals like follower count or verification status.
Subscriber-only benefits: Offer perks to Coinbase One members without building subscription infrastructure.
Creator programs: Identify real creators using engagement thresholds instead of empty accounts.
Base Verify is available today for builders. Please fill out this form to request access to Base Verify. Check out the documentation here.
If you’re building incentives, rewards, gated access, or reputation systems inside Mini Apps, we’d love to collaborate.

gBase friends! 𝐁𝐚𝐬𝐞 𝐕𝐞𝐫𝐢𝐟𝐲 ✅ I already recorded a short video about where to find it in @baseapp and what this tool looks like 🙂↔️ And now @base.base.eth has published an entire blog article blog.base.dev/base-verify about Base Verify, and it has become clearer why it is needed and why it is an important step for Mini Apps. 𝑊𝑒 𝑎𝑟𝑒 𝑎𝑙𝑟𝑒𝑎𝑑𝑦 𝑢𝑠𝑒𝑑 𝑡𝑜 𝑡ℎ𝑒 𝑖𝑑𝑒𝑎 𝑡ℎ𝑎𝑡 "𝑤𝑎𝑙𝑙𝑒𝑡 = 𝑢𝑠𝑒𝑟". 𝐵𝑢𝑡 𝑖𝑛 𝑜𝑛𝑐ℎ𝑎𝑖𝑛, 𝑡ℎ𝑖𝑠 𝑜𝑓𝑡𝑒𝑛 𝑚𝑒𝑎𝑛𝑠: 𝑜𝑛𝑒 𝑝𝑒𝑟𝑠𝑜𝑛 → 20 𝑤𝑎𝑙𝑙𝑒𝑡𝑠 → 20 𝑠𝑡𝑎𝑚𝑝𝑠 😅 𝐴𝑛𝑑 𝑎𝑛𝑦 𝑟𝑒𝑤𝑎𝑟𝑑𝑠 / 𝑞𝑢𝑒𝑠𝑡𝑠 / 𝑎𝑖𝑟𝑑𝑟𝑜𝑝𝑠 / 𝑔𝑎𝑡𝑒𝑑 𝑎𝑐𝑐𝑒𝑠𝑠 𝑡𝑢𝑟𝑛 𝑖𝑛𝑡𝑜 𝑎 𝑐𝑜𝑚𝑝𝑒𝑡𝑖𝑡𝑖𝑜𝑛 𝑏𝑒𝑡𝑤𝑒𝑒𝑛 𝑓𝑎𝑟𝑚𝑒𝑟𝑠. Base Verify solves the sybil farm problem elegantly 😉 → provides a deterministic identifier for the real user → without revealing personal data to the application → and allows you to check conditions such as creator/subscription/followers in a "yes/no" format, without leaking the source data. 𝐘𝐨𝐮 𝐠𝐨 𝐭𝐡𝐫𝐨𝐮𝐠𝐡 𝐯𝐞𝐫𝐢𝐟𝐢𝐜𝐚𝐭𝐢𝐨𝐧 𝐯𝐢𝐚 𝐗/𝐂𝐨𝐢𝐧𝐛𝐚𝐬𝐞/𝐈𝐧𝐬𝐭𝐚𝐠𝐫𝐚𝐦/𝐓𝐢𝐤𝐓𝐨𝐤 and receive an identifier. Then the user is verified once, and this verification works in all Mini Apps that use Base Verify. This is already working in the Base App on a scale of 200,000+ verifications and growing 👀 Have you passed verification and connected your applications to BaseApp? Stay Based 🫂 https://x.com/eternia_xx/status/1997215477794591122?s=46
actually nice to have something that stops the farmers without being a total pain
😌🤲
Thanks, Mioku

love to integrate this on @beeper thanks for this infrastructure @base.base.eth !
How is this different from all the other human verification services?
👀 👀
@farcasteradmin.eth does this belong in $EGGS app?
Don't anyone complete an account creation without verifying at least one social.
Game dead if kyc Sir 🤷
Really great tools for Base 😇
Lol they are officially waving the white flag. Pathetic.
