TL;DR: Kaito has integrated Brevis’s zero-knowledge attestation technology, enabling any campaign on Kaito to verify on-chain (and soon off-chain) credentials while preserving complete privacy. Users can now prove wallet qualifications without revealing which wallet they own. The Brevis Yapper Leaderboard becomes the first campaign to use this feature, launching Phase 2 today where yappers can attest on-chain profiles to unlock multipliers that boost their credibility on the leaderboard rankings.
Kaito x Brevis: A New Standard for InfoFi
Kaito and Brevis have partnered to bring privacy-preserving on-chain verification to Kaito’s platform. Through this integration, any campaign running on Kaito can now verify users’ on-chain profiles using Brevis ZK proofs, all without exposing wallet addresses.
This solves a fundamental limitation in InfoFi rewards: campaigns could only track social metrics because verifying on-chain behavior meant forcing users to publicly connect their wallets. Now, users can prove they’re long-term holders, active DeFi participants, or any set of valuable traits and activities without doxxing their portfolios.
The technology is now live on Kaito’s platform, and the Brevis Yapper Leaderboard is the first campaign to implement it.
Brevis Yapper Leaderboard Phase 2
On September 23, we launched the Brevis Yapper Leaderboard on Kaito to recognize the voices shaping our community. Of course, we couldn’t just run a standard social campaign, so we partnered with Kaito to bring zero-knowledge proofs into the mix. Phase 1 ranked yappers purely by social contribution using Kaito’s mindshare algorithm.
Today, Phase 2 goes live using this new ZK attestation feature. Yappers can now prove their on-chain profiles without exposing their wallet and earn multipliers that boost their credibility on the leaderboard ranking. Quality content still matters, but on-chain behavior now matters too. All while privacy remains intact throughout.
How ZK Multipliers Work
Your Mindshare score comes from Kaito’s algorithm analyzing your social contributions (quality content, meaningful engagement, influence).
Your Multiplier comes from proving on-chain profiles and activities. Meet the eligibility criteria and attest your wallet to unlock a multiplier (1.25x for this initial batch).
Your Contribution score is your final ranking: Mindshare × Multiplier relative to all participants.
Example: Consider a simplified leaderboard with two participants:
- Alice has 50% mindshare, attests and gets 1.25x multiplier
- Bob has 50% mindshare, doesn’t attest and gets no multiplier (1x)
Alice’s contribution = (50 × 1.25) / (50 × 1.25 + 50 × 1) = 62.5 / 112.5 = 55.6%
Bob’s contribution = (50 × 1) / 112.5 = 44.4%
Alice gained 5.6 percentage points by attesting. Attesting creates a real advantage, especially valuable for genuine contributors when many participants don’t meet the on-chain criteria.
Privacy-Preserving Attestation
The attestation uses Brevis ZK proofs to verify your wallet qualifications without revealing which wallet you own.
When you attest, the system generates a zero-knowledge proof that confirms:
- You own a wallet that meets the eligibility criteria
- That wallet is linked to your Kaito account
- The multiplier calculation is correct
Nobody can see which wallet belongs to which Kaito account. Not Kaito, not Brevis, not other participants. The proof verifies everything without exposing anything.
Current Eligibility Criteria
For the Brevis Yapper Leaderboard, we’ve chosen to recognize holders of tokens from our partner projects. This demonstrates how zero-knowledge attestation creates value for these communities: active participation and loyalty in projects like Linea, OpenEden, Usual, Kaito, and MetaMask (mUSD) can now be recognized and rewarded without sacrificing privacy.
To unlock the 1.25x multiplier and Proof-of-Activity badge, your wallet must meet any one of these criteria (based on time-weighted average holdings over the past 7 days):
- $LINEA holding balance ≥ 70000
- $EDEN holding balance ≥ 7000
- $USUAL holding balance ≥ 30000
- $KAITO holding balance ≥ 1000
- $sKAITO holding balance ≥ 1000
- $mUSD holding balance ≥ 1000
Meeting any single criterion qualifies you for the multiplier. You don’t need to hold all tokens, just one at the threshold.
These are the criteria we’ve set for our campaign, but future projects running campaigns on Kaito can define their own metrics based on what they want to reward. The result is always the same: real activity, genuine loyalty, and meaningful usage get recognized without ever compromising on privacy or anonymity.
How to Attest
- Visit private-attestation.brevis.network to participate in Phase 2.
- Attest (Wallet Connection Required) Connect the wallet you want to prove for on-chain eligibility.
- Once your wallet is connected, click on the button that checks your wallet eligibility. The system verifies your holdings, generates the ZK proof, and links the attestation to your Kaito account. Once complete, your Proof-of-Activity badge appears on the leaderboard and your multiplier applies to your Contribution score.
The wallet address you connect remains completely private and won’t be revealed anywhere.
Attest Now, Criteria May Change
Current eligibility is based on token holdings for Brevis partner projects. These criteria are subject to change. We may adjust multiplier values, add new metrics to attest, or remove existing ones as Phase 2 progresses.
Attest as soon as possible if you currently meet the criteria. Future changes won’t affect attestations already completed, but waiting risks missing the current eligibility window.
Fairness Without Compromise
Reward campaigns have only tracked social metrics because that’s all they could verify publicly. Your on-chain contributions existed but stayed invisible, proving them meant exposing your wallet.
Brevis ZK proofs have now revolutionized the game. Campaigns can now verify on-chain history, protocol usage, and holding patterns while keeping wallets completely private. The Brevis Yapper Leaderboard is the first implementation of this new standard.
The implications go far beyond our own campaign. We built infrastructure that makes verifiable, privacy-preserving rewards possible for any project. The metrics that should matter most can now actually count.
The leaderboard is live, Phase 2 is active, and attestation is open.
