Selective Proofs. Total Privacy. Borderless Utility.
In the rapidly evolving world of Web3, identity is no longer just a wallet address it’s your entire onchain footprint. But what if you could prove your onchain credentials across any network without revealing everything about yourself? Welcome to Lagrange, the modular ZK-powered identity layer changing the way Web3 verifies trust, privacy, and utility.
What Is @Lagrange Official ?
Lagrange is a next-gen infrastructure protocol designed to make selective zero-knowledge (ZK) data proofs available to any dApp, chain, or protocol. Instead of exposing your full transaction history or wallet contents, Lagrange lets users generate privacy-preserving proofs of eligibilitymuseful for everything from governance roles to DeFi access and airdrop rewards.
Whether you're a DAO voter, DeFi power user, or NFT collector, Lagrange allows you to verify your identity on-chain while staying anonymous.
Key Features
Selective ZK Data Proofs
Generate cryptographic proofs for specific wallet behavior—without revealing unrelated transactions.
Cross-Chain Eligibility
Prove eligibility across multiple chains—Ethereum, Arbitrum, Base, and beyond.
Privacy-First Access Control
Join gated apps, claim airdrops, or unlock roles—all without full doxxing.
Built for Developers
Lagrange integrates easily with existing smart contracts, so builders can embed identity logic into any protocol.
Real Use Cases in Action
Here’s what Lagrange unlocks for the Web3 world:
DAO Role Claims: Prove voting history or participation for gated access across networks.
DeFi Tiered Access: Demonstrate trading volume or liquidity contribution to unlock premium tools or yield tiers.
Private Airdrops: Claim rewards without revealing your full wallet or linking identities across platforms.
Gated Content or Utility: Access token-gated dApps and events with anonymized proof of ownership.
