overview
CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built by Web3 experts to power your token, DeFi, or NFT project.

We architect and deploy custom smart contracts on EVM-compatible chains (Ethereum, Polygon, Arbitrum) and Solana. Our process delivers audit-ready code in weeks, not months.

  • Token Systems: ERC-20, ERC-721, ERC-1155, and custom tokenomics with vesting, staking, and governance.
  • DeFi Protocols: Automated Market Makers (AMMs), lending/borrowing pools, yield aggregators, and derivative contracts.
  • Enterprise Logic: Custom business logic for supply chain, gaming, real-world assets (RWA), and membership systems.

We build with security as the foundation. Every contract follows OpenZeppelin standards and undergoes internal review before delivery for third-party audit.

Our development includes comprehensive testing (unit, integration, forking), gas optimization reports, and full deployment support to mainnet. We ensure your contracts are upgradeable and maintainable for long-term success.

WHAT WE DELIVER

Core Capabilities of a Dedicated Real-Time Explorer

Our dedicated infrastructure provides more than just a data feed. We deliver a production-grade, high-fidelity window into blockchain state, designed for applications that cannot afford latency or data loss.

01

Sub-Second Transaction Visibility

Monitor pending transactions and new blocks with < 500ms latency from network propagation. This real-time visibility is critical for arbitrage, front-running protection, and dynamic fee estimation.

< 500ms

Transaction Coverage
02

Enterprise-Grade Data Integrity

Receive validated, structured transaction data with guaranteed ordering and zero data loss. Our systems implement cryptographic verification and automatic reconnection to ensure a complete, accurate feed.
