Cross-Chain Identity Aggregator

We develop custom identity aggregators that unify user credentials, reputations, and on-chain activity across multiple blockchains into a single, verifiable source of truth for your dApp.

overview
FOUNDATION

Blockchain Infrastructure Development

Build secure, scalable blockchain backends tailored for high-performance Web3 applications.

We architect and deploy the core infrastructure your application needs to succeed: custom RPC nodes, secure validator setups, and optimized indexing services. This eliminates the operational overhead of managing blockchain infrastructure in-house.

  • Node Management: Dedicated EVM and Solana RPC endpoints with 99.9% uptime SLA and advanced monitoring.
  • Indexing & APIs: Real-time data pipelines for on-chain events, token balances, and NFT metadata.
  • Security First: Infrastructure built with defense-in-depth principles, including DDoS protection and private key management best practices.

Focus on your product's logic while we ensure your foundation is robust, performant, and ready to scale from prototype to production.

PROVEN METHODOLOGY

Our Development & Integration Process

A structured, security-first approach to deliver a production-ready identity layer in weeks, not months. We handle the technical complexity so you can focus on your core product.

01

Architecture & Protocol Design

We design a custom, scalable identity schema and select the optimal protocols (e.g., ERC-725, Verifiable Credentials, EIP-4361) for your specific cross-chain use case, ensuring interoperability and future-proofing.

FULL-STACK INFRASTRUCTURE

Custom Blockchain Development

End-to-end blockchain solutions built for production scale and security.

We architect and deploy custom blockchain networks, sidechains, and L2 solutions tailored to your specific transaction volume and governance needs. Our full-stack approach ensures seamless integration with your existing systems.

  • Private/Consortium Networks: Deploy a dedicated Hyperledger Fabric or EVM-compatible chain with custom consensus in under 4 weeks.
  • Scalable Layer-2s: Build on Arbitrum, Optimism, or zkSync stacks to achieve >2,000 TPS with sub-cent fees.
  • Cross-Chain Bridges: Develop secure, audited bridges for asset and data transfer between networks, featuring multi-sig governance and continuous monitoring.

From initial design to mainnet launch and ongoing node operations, we provide a single point of accountability for your core blockchain infrastructure.

Technical & Commercial Details

Cross-Chain Identity Aggregator FAQs

Get clear, specific answers to the most common questions from CTOs and technical founders evaluating identity solutions.

For a standard deployment targeting 2-3 major chains (e.g., Ethereum, Polygon, Arbitrum), the typical timeline is 4-6 weeks from kickoff to mainnet launch. This includes architecture design, smart contract development, integration with your dApp, security audit, and deployment. Complex multi-chain ecosystems or novel verification logic can extend this to 8-10 weeks. We provide a detailed, phase-gated project plan at the start.
