CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built by Web3 specialists.

We architect and deploy custom smart contracts that form the foundation of your dApp. Our development process ensures security-first design, gas optimization, and comprehensive audit readiness from day one.

  • Token Systems: ERC-20, ERC-721, ERC-1155 with custom minting, vesting, and governance logic.
  • DeFi Protocols: Automated market makers (AMMs), lending/borrowing pools, yield aggregators, and staking contracts.
  • Enterprise Logic: Multi-signature wallets, access control systems, and custom business logic for real-world asset (RWA) tokenization.

We deliver battle-tested contracts with a focus on mainnet security and long-term maintainability, reducing your time-to-market from months to weeks.

Blockchain API Development

High-performance, reliable APIs that connect your application to the blockchain.

We build custom REST and WebSocket APIs that abstract blockchain complexity, providing your team with simple endpoints for complex operations. This reduces your development time by up to 60% and eliminates the need to manage low-level node infrastructure.

  • Multi-Chain Support: Unified interfaces for EVM chains (Ethereum, Polygon, Arbitrum) and Solana.
  • Real-Time Data: WebSocket feeds for instant notifications on transactions, blocks, and wallet activity.
  • Enhanced Reliability: Built-in retry logic, load balancing, and 99.9% uptime SLAs.

Our APIs are designed for scale, handling thousands of requests per second with sub-100ms latency. We provide comprehensive documentation, SDKs, and dedicated support to ensure your integration is seamless and future-proof.

Frequently Asked Questions

Common questions about modernizing your existing infrastructure with a secure blockchain layer.

Deployment timelines range from 4 to 12 weeks, depending on the complexity of your existing APIs, data models, and the target blockchain. A standard REST API integration with an EVM chain typically takes 4-6 weeks. We provide a detailed project plan after the initial technical assessment.
