CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3-native engineers.
- Custom Tokenomics: Design and implement
ERC-20,ERC-721, andERC-1155tokens with tailored minting, staking, and governance logic. - DeFi Protocols: Build automated market makers (AMMs), lending pools, and yield aggregators with sub-second finality.
- Enterprise Integration: Create upgradable contracts with
UUPSor transparent proxies, managed via a secure multi-sig wallet.
We deliver a fully tested, documented, and deployable contract suite in 2-4 weeks, backed by a 99.9% uptime SLA for mainnet deployments. Our code undergoes internal review against common vulnerabilities before your formal audit.

Technical & Commercial Considerations
Tax Oracle Development: Key Questions
Answers to the most common questions from CTOs and founders evaluating specialized oracle infrastructure for tax and compliance applications.
A standard tax oracle deployment takes 2-4 weeks for a single jurisdiction. Complex multi-jurisdiction systems with custom logic can extend to 6-8 weeks. Our phased approach includes a 1-week discovery and scoping sprint, followed by development, rigorous testing, and a final security review before mainnet deployment.
