SOCIAL AUTH FOR SCALING LAYERS
Core Technical Capabilities
We deliver production-ready, secure social authentication infrastructure for ZK and Optimistic Rollups, accelerating user onboarding while maintaining decentralization.
04
Security & Audit-Ready Code
All smart contracts and off-chain verifiers are built with OpenZeppelin standards, undergo internal audits, and are delivered with comprehensive test suites. We focus on mitigating common vulnerabilities like signature replay and front-running.
05
Custom Onchain Reputation & Sybil Resistance
Leverage authenticated social data to build onchain reputation scores or implement Sybil-resistant airdrops and governance. We create the logic that ties verified social profiles to wallet addresses for your specific use case.

Frequently Asked Questions
Get clear answers on how we deliver secure, scalable social authentication for your rollup-based applications.
A standard implementation with 2-3 social providers (e.g., Google, Twitter, Discord) takes 2-4 weeks from kickoff to production-ready deployment. Complex integrations with custom identity schemas or multi-chain support may extend to 6-8 weeks. We provide a detailed project plan in the initial scoping call.
