CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3-native engineers.
We architect and deploy custom smart contracts that are secure, gas-optimized, and tailored to your specific business logic. Our team specializes in Solidity 0.8+, Rust (Solana), and Move (Aptos/Sui), ensuring your foundation is built on the right technology.
Every contract undergoes a rigorous security review and is developed with
OpenZeppelinstandards and formal verification principles to mitigate risk.
- Full Lifecycle Support: From initial design and development to deployment, auditing, and ongoing maintenance.
- Key Deliverables: ERC-20/721/1155 tokens, custom DeFi protocols, DAO governance systems, and cross-chain bridges.
- Measurable Outcome: Reduce time-to-market by weeks with battle-tested code and a 99.9% uptime SLA for mainnet deployments.

Frequently Asked Questions
Get clear answers about our Aptos & Sui biometric module development process, security, and support.
A standard biometric authentication module for Aptos or Sui can be deployed in 2-4 weeks. This includes design, Move smart contract development, integration with off-chain biometric providers (like WebAuthn or device-native APIs), and initial testing. Complex implementations with custom on-chain logic or multi-chain support may extend to 6-8 weeks. We provide a detailed project plan with milestones during the initial scoping call.
