ENGINEERING EXCELLENCE
Core Technical Capabilities We Deliver
We architect and deploy secure, scalable identity infrastructure that bridges ecosystems. Our solutions are built on verifiable engineering principles, not marketing promises.
01
Cross-Chain Identity Protocol Design
We design and implement custom identity protocols using ERC-725, ERC-1056 (Lightweight Identity), and ERC-6551 (Token-Bound Accounts). Our architecture ensures your social graph and reputation are portable across EVM and non-EVM chains without vendor lock-in.

02
Decentralized Identifier (DID) & VC Integration
Implement W3C-compliant Decentralized Identifiers (DIDs) and Verifiable Credentials (VCs) for portable, user-owned identity. We integrate with existing identity providers and social logins to bootstrap your user base with verified, on-chain attestations.
W3C Compliant

OAuth2.0/OpenID
Provider Integration
03
Zero-Knowledge Proof (ZKP) Privacy Layer
Incorporate zk-SNARKs and zk-STARKs to enable selective disclosure of identity attributes. Users can prove membership, reputation thresholds, or KYC status without revealing underlying data, ensuring compliance and user sovereignty.

On-Chain Reputation & Sybil Resistance
Build Sybil-resistant reputation systems using on-chain activity, attestation graphs, and stake-based mechanisms. Our models prevent spam and fraud while accurately quantifying user trust and influence across multiple dApps.

Secure Smart Contract & Relayer Infrastructure
Develop and audit gas-optimized smart contracts for identity management, using OpenZeppelin libraries and formal verification where applicable. We deploy with secure, non-custodial meta-transaction relayers to abstract gas fees for end-users.

Frequently Asked Questions
Common questions from CTOs and product leads about implementing a secure, scalable social identity federation layer.
A production-ready MVP with core federation features (e.g., wallet linking, on-chain attestations) typically deploys in 4-6 weeks. Complex integrations with multiple existing social platforms or custom governance models can extend to 8-12 weeks. We provide a detailed project plan with weekly milestones after the initial technical discovery session.
