CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built for scale and compliance.
- Custom Tokenomics: Design and implement
ERC-20,ERC-721, andERC-1155tokens with vesting, staking, and governance modules. - DeFi & NFT Protocols: Build automated market makers (AMMs), lending pools, and dynamic NFT collections with gas-optimized logic.
- Enterprise Integration: Create upgradable proxy contracts with multi-sig admin controls and compliance hooks for real-world assets (RWA).
We guarantee zero critical vulnerabilities in our delivered code, backed by a pre-audit from our internal security team. Typical delivery for a core protocol is 4-6 weeks.

CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built on `Solidity` and `Rust` for DeFi, NFTs, and enterprise applications.
We architect and deploy custom smart contracts that are gas-optimized, audited, and upgradeable. Our development process ensures your core logic is secure and future-proof from day one.
- Full lifecycle support: From initial design and
Hardhat/Foundrytesting to mainnet deployment and monitoring. - Security-first approach: All code follows OpenZeppelin standards and undergoes internal review before third-party audits with firms like CertiK or Quantstamp.
- Multi-chain ready: Deployable on EVM chains (Ethereum, Polygon, Arbitrum) and Solana.
Reduce your time-to-market and technical risk with battle-tested contract patterns.
We deliver contracts for:
- DeFi Protocols: DEXs, lending/borrowing platforms, yield aggregators.
- Digital Assets: Custom
ERC-20,ERC-721, andERC-1155tokens with advanced features. - Utility & Governance: DAO frameworks, vesting schedules, and multi-signature management.

Frequently Asked Questions
Get clear, technical answers to common questions about building a secure, compliant, and scalable subscription portal for your tokenized fund or asset.
For a standard portal with KYC/AML, multi-chain support, and fiat on/off-ramps, deployment takes 4-6 weeks from kickoff to mainnet launch. This includes 2 weeks for smart contract development and audit, 2 weeks for frontend integration, and 2 weeks for testing and security review. Complex requirements like custom vesting schedules or multi-sig treasury management can extend the timeline.
