CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3-native engineers.
From tokenomics to governance, we translate your business logic into immutable, on-chain code.
- Custom Token Standards:
ERC-20,ERC-721,ERC-1155, and bespoke implementations. - DeFi Primitives: Automated Market Makers (AMMs), lending/borrowing pools, staking mechanisms.
- Security-First: Development follows OpenZeppelin standards and includes pre-audit threat modeling.
- Full Lifecycle: Development, testing (
Hardhat/Foundry), deployment, and post-launch monitoring.

CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built to your exact specifications.
We architect and deploy custom smart contracts that power your dApp's core logic. Our development process is built on security-first principles, utilizing OpenZeppelin standards and rigorous internal audits to mitigate risk before deployment.
- Custom Tokenomics: Design and implement
ERC-20,ERC-721, orERC-1155tokens with tailored minting, vesting, and governance logic. - DeFi & DEX Logic: Build automated market makers (AMMs), staking pools, yield aggregators, and lending protocols with gas-optimized Solidity.
- Enterprise Integration: Create secure oracles, cross-chain bridges, and upgradeable contracts using
Proxypatterns for future-proofing.
We deliver battle-tested contracts with comprehensive documentation, enabling your team to launch with confidence in under 4 weeks.

Technical and Commercial FAQs
Get specific answers on timelines, costs, security, and support for our Cross-Chain Data Payment Gateway service.
A standard Cross-Chain Data Payment Gateway deployment takes 3-5 weeks from kickoff to mainnet launch. This includes 1 week for requirements finalization, 2-3 weeks for core development and integration, and 1 week for testing and security review. Complex multi-chain deployments with custom oracles may extend to 8 weeks.
