CORE SERVICE
Smart Contract Development
Secure, gas-optimized smart contracts built to your exact specifications.
- Full-Cycle Development: From initial concept and
Solidity/Rustcoding to deployment onEVM/Solana/Cosmoschains and ongoing maintenance. - Security-First Approach: All code undergoes manual review, automated analysis with
Slither/MythX, and formal verification for critical logic. - Gas Optimization: We specialize in writing efficient code, routinely achieving 20-40% gas savings versus unaudited implementations.
We deliver contracts you can trust, with transparent processes and clear documentation for your team.
- Comprehensive Deliverables: You receive the verified source code, technical specification document, audit-ready test suite (≥95% coverage), and deployment scripts.
- Protocol Integration: Seamless integration with
ERC-20,ERC-721,ERC-1155, DeFi oracles (Chainlink), and cross-chain bridges.

BUILT FOR SCALE AND PRIVACY
Core Technical Capabilities
Our engineering team delivers production-ready infrastructure and cryptographic primitives, enabling you to launch a compliant, high-performance tipping application without compromising on user privacy or security.
01
Zero-Knowledge Identity & Reputation
Implement Semaphore or Tornado Cash-like protocols to enable anonymous tipping while maintaining Sybil resistance and user reputation scores. We ensure proof generation remains under 2 seconds for a seamless UX.
