CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built for your specific business logic and audited for deployment.
From tokenomics to governance, we translate your requirements into immutable, reliable on-chain logic.
- Custom Token Contracts:
ERC-20,ERC-721,ERC-1155with bespoke minting, vesting, and utility features. - DeFi & DEX Logic: Automated market makers (AMMs), liquidity pools, staking, and yield farming mechanisms.
- Security-First Process: Development includes formal verification, unit/integration testing, and a pre-audit review to minimize vulnerabilities.
- Deployment & Verification: Full support for deployment on
EVMchains (Ethereum, Polygon, Arbitrum) andSolana, including contract verification on block explorers.

Real-Time Data Marketplace Development FAQ
Answers to common questions from CTOs and product leaders evaluating development partners for on-chain data streaming infrastructure.
We follow a structured 4-phase agile process. Discovery & Architecture (1-2 weeks): Requirements gathering, tokenomics design, and system architecture. Core Development (3-5 weeks): Building smart contracts (Solidity/Rust), off-chain indexers, and the publisher/subscriber APIs. Testing & Audit (2 weeks): Comprehensive unit/integration tests and a security review by our internal audit team. Deployment & Launch (1 week): Mainnet deployment, frontend integration, and go-live support. A complete MVP typically launches in 7-10 weeks.
