CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3-native engineers.
From a 2-week MVP to a full protocol suite, we deliver code that is secure, gas-optimized, and ready for mainnet.
Our process includes:
- Comprehensive security review with static analysis and manual auditing.
- Gas optimization to reduce user transaction costs by up to 40%.
- Full documentation and deployment scripts for seamless handoff.
We specialize in:
- Token Systems: Custom
ERC-20,ERC-721, andERC-1155with advanced features like vesting and governance. - DeFi Primitives: Automated Market Makers (AMMs), lending/borrowing pools, and staking contracts.
- Enterprise Logic: Custom business logic for asset tokenization, supply chain, and secure multi-signature operations.

Frequently Asked Questions
Get clear answers on our development process, timelines, security, and support for building a secure mobile identity bridge.
For a minimum viable product (MVP) with core wallet and identity bridging features, development typically takes 8-12 weeks. This includes design, smart contract development, mobile SDK integration, and security audits. Complex features like multi-chain governance or advanced privacy layers can extend the timeline to 16-20 weeks. We provide a detailed project plan within the first week of engagement.
