overview
FULL-STACK INFRASTRUCTURE

Custom Blockchain Development

End-to-end blockchain solutions from protocol design to mainnet deployment.

We architect and build production-grade blockchain systems tailored to your specific use case. Our team delivers complete, audited networks—from layer-1 protocols and custom sidechains to interoperable app-chains. > Deploy a purpose-built chain in under 6 weeks.

  • Core Protocol Development: Custom consensus (PoS, PoA), tokenomics, and governance modules.
  • Smart Contract Suites: Gas-optimized Solidity/Rust contracts with formal verification.
  • Node Infrastructure: Managed validators, RPC endpoints, and block explorers with 99.9% uptime SLA.
  • Cross-Chain Bridges: Secure, audited bridges for assets and data (IBC, LayerZero, Axelar).

We handle the full lifecycle: white paper technical design, testnet deployment, security audits (3rd-party), and mainnet launch support. Avoid vendor lock-in with open-source, modular code.

Our Delivery Methodology

We deliver production-ready EVM-Based DID systems through a structured, client-centric process. Our methodology ensures technical excellence, security, and alignment with your business goals from day one.

01

Discovery & Architecture Design

We begin with a deep dive into your use case, compliance needs, and target chains (Ethereum, Polygon, Arbitrum, etc.). We deliver a detailed technical specification and architecture blueprint for your DID system, covering standards (ERC-725, ERC-1056, ERC-3643), key management, and integration points.

1-2 weeks
Design Phase
100%
Specification Clarity
02

Smart Contract Development & Auditing

Our engineers build modular, upgradeable smart contracts using Solidity 0.8+ and OpenZeppelin libraries. Every contract undergoes rigorous internal review and is submitted for a formal security audit by a leading firm like Trail of Bits or ConsenSys Diligence before deployment.

2+ Audits

Gas-Optimized
Code Standard
03

Frontend SDK & Integration

We provide a lightweight, type-safe SDK (React/TypeScript) for seamless wallet connection, credential issuance, and verification. We handle the full-stack integration with your application, including secure backend validators and API gateways for off-chain attestations.
