overview
FULL-STACK INFRASTRUCTURE

Custom Blockchain Development

End-to-end blockchain solutions built for enterprise-grade performance and security.

We architect and deploy custom blockchain networks and applications from the ground up. Our full-cycle development delivers production-ready systems in 6-12 weeks, with 99.9% uptime SLAs and comprehensive security audits.

From private consortium chains to public mainnet deployments, we build the foundational layer for your digital assets and decentralized applications.

  • Core Protocol Development: Custom EVM-compatible chains, Substrate-based parachains, and Cosmos SDK app-chains.
  • Smart Contract Suites: Secure Solidity/Rust development for ERC-20, ERC-721, and custom token standards.
  • Node Infrastructure: Managed validator networks, RPC endpoints, and block explorers with real-time monitoring.
  • Integration & APIs: Seamless connectivity with existing enterprise systems and off-chain data via Chainlink oracles.

CORE SERVICE

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, utilizing audited libraries like OpenZeppelin and formal verification tools to mitigate risk before deployment.

From tokenization (ERC-20, ERC-721) to complex DeFi primitives, we deliver contracts that are gas-optimized, upgradeable, and fully documented for your team.

  • End-to-End Delivery: Specification, development, testing (Hardhat/Foundry), and mainnet deployment.
  • Security Audits: Integration with top firms for third-party review and SLA-backed post-launch monitoring.
  • Compliance Ready: Built-in patterns for regulatory requirements like transfer pausing and allowlists.
Security Assessment Process

Frequently Asked Questions on Relayer Security

Get clear answers on our methodology, timeline, and deliverables for securing your cross-chain infrastructure.

Our assessment follows a structured, three-phase methodology: Discovery & Architecture Review (documenting all components and data flows), Automated & Manual Testing (simulating attacks on transaction validation, state management, and governance), and Remediation & Reporting (providing a prioritized action plan with proof-of-concept fixes). We test against the OWASP Top 10 for Web3 and Chainscore's proprietary threat matrix for cross-chain systems.
