We architect and deploy custom Solidity/Rust smart contracts with enterprise-grade security and gas optimization. Our process includes formal verification, comprehensive unit testing, and third-party audits from firms like CertiK and Quantstamp to eliminate vulnerabilities before mainnet deployment.

overview
CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built for scale and compliance.
- Token Standards: Custom
ERC-20,ERC-721,ERC-1155, andERC-4626Vaults. - DeFi Primitives: Automated Market Makers (AMMs), lending pools, staking contracts, and yield strategies.
- Governance Systems: DAO frameworks, multi-sig wallets, and transparent proposal mechanisms.
- Cross-Chain: Secure bridging logic and omnichain messaging with
LayerZeroorWormhole.
We deliver battle-tested code that reduces deployment risk and ensures your protocol's economic security from day one.
Our development lifecycle ensures 2-4 week MVP delivery for standard contracts, with ongoing maintenance and upgrade management via transparent proxy patterns.

END-TO-END ORACLE MIGRATION
Our Migration & Upgrade Capabilities
We execute secure, zero-downtime migrations from legacy oracles (e.g., Chainlink, Band) to modern, cost-effective alternatives like Pyth Network or API3. Our process ensures data continuity and contract integrity.
01
Comprehensive Pre-Migration Audit
We perform a full security and dependency analysis of your existing oracle integrations. This identifies risks, gas inefficiencies, and data source dependencies before migration begins.
