- Enterprise Logic: Custom business rules, multi-signature controls, and compliance-ready features like allowlists.
- Full Lifecycle: Development, testing (
Hardhat/Foundry), auditing, and mainnet deployment with 99.9% uptime monitoring.
Core Components We Deliver
We build and integrate the complete technical stack for a portable, secure, and user-owned identity layer, accelerating your time-to-market.
Cross-Chain Identity Registry
Deploy a canonical, non-upgradable registry smart contract that serves as the single source of truth for user profiles, with mappings to addresses across Ethereum, Polygon, and other EVM chains.
Decentralized Profile Resolver
A lightweight, gas-optimized resolver contract that fetches and aggregates profile data (ENS, Lens, Farcaster) on-chain, enabling seamless interoperability without vendor lock-in.
Secure Attestation Framework
Implement an EAS-compatible system for issuing and verifying on-chain credentials (KYC, reputation, achievements) with customizable schemas and revocation controls.
Unified SDK & API Gateway
A developer-friendly TypeScript SDK and managed API layer for easy integration, handling chain abstraction, caching, and real-time profile state synchronization.
Gas-Optimized Transaction Relayer
A meta-transaction infrastructure enabling gasless profile updates and social interactions for users, with sponsored gas policies and batched operations to reduce costs.
Comprehensive Security Suite
End-to-end security including smart contract audits (submitted to Code4rena), monitoring for Sybil resistance, and rate-limiting to protect against spam and abuse.
Why a Portable Profile System Drives Growth
An interoperable identity layer isn't just a technical feature—it's a strategic growth engine. Here's how our development service delivers measurable business outcomes.
Accelerate User Onboarding
Reduce sign-up friction by 70%+ with portable credentials. Users bring their verified identity and reputation from other platforms, eliminating redundant KYC and trust-building steps.
Unlock Cross-Protocol Liquidity
Enable seamless user movement between DeFi, gaming, and social apps. A unified profile allows for shared reputation scores and collateralized identities, increasing capital efficiency across your ecosystem.
Enhance Security & Compliance
Build with verifiable credentials and zero-knowledge proofs. Our systems are designed for privacy-by-default, reducing regulatory risk and protecting user data while enabling compliant on-chain interactions.
Future-Proof Your Product Stack
Avoid vendor lock-in with standards-based development (ERC-725, ERC-6551). Our portable profile architecture ensures compatibility with emerging protocols and simplifies integration with new partners.

Our Development & Integration Process
A structured, security-first approach to building and integrating your interoperable profile system, designed for rapid deployment and seamless scalability.
Architecture & Protocol Design
We design the foundational architecture, selecting and customizing the optimal interoperability protocol (e.g., LayerZero, Axelar, Wormhole) and token standards (ERC-6551, ERC-725) for your specific use case.
Smart Contract Development
Development of secure, gas-optimized smart contracts for profile logic, account abstraction, and cross-chain messaging. Built with Solidity 0.8+ and OpenZeppelin libraries.
Security Audit & Verification
Rigorous internal and third-party smart contract auditing. We facilitate audits with leading firms like CertiK or Quantstamp to ensure enterprise-grade security before mainnet deployment.
Frontend & SDK Integration
Development of user-facing applications and developer SDKs (React/TypeScript) for seamless profile management, wallet connection, and cross-chain interactions.
Testnet Deployment & Staging
Comprehensive deployment on testnets (Sepolia, Mumbai, etc.) with simulated cross-chain transactions. We conduct load testing and user acceptance testing (UAT) in a staging environment.
Mainnet Launch & Monitoring
Managed mainnet deployment across your target chains (Ethereum, Polygon, Arbitrum). We provide 24/7 monitoring, alerting, and performance dashboards post-launch.
Smart Contract Development
Secure, production-ready smart contracts built for scale and compliance.
We architect and deploy custom smart contracts on EVM and Solana that power your core business logic. Our focus is on security-first development, leveraging audited patterns from OpenZeppelin and rigorous internal testing to mitigate risks before deployment.
- Token Systems:
ERC-20,ERC-721,ERC-1155, andSPLtokens with custom minting, vesting, and governance logic. - DeFi Protocols: Automated Market Makers (AMMs), lending/borrowing pools, staking mechanisms, and yield optimizers.
- Enterprise Logic: Multi-signature wallets, asset tokenization platforms, and compliant KYC/AML integration modules.
- Full Audit Trail: Every contract includes comprehensive documentation,
NatSpeccomments, and is prepared for third-party audit.
We deliver battle-tested code that reduces time-to-market by weeks and provides a foundation you can trust for millions in TVL.
Frequently Asked Questions
Common questions from CTOs and product leads about building and deploying cross-chain identity solutions.
A production-ready MVP with core features (profile creation, attestations, multi-chain resolution) typically deploys in 3-5 weeks. Complex systems with custom governance, advanced privacy, or integration with 5+ chains can take 6-10 weeks. Our agile sprints deliver working code every 2 weeks.
