CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3-native engineers.
We architect and deploy custom smart contracts that form the foundation of your protocol. Our development process ensures security-first design, gas optimization, and comprehensive audit readiness from day one.
- Token Systems:
ERC-20,ERC-721,ERC-1155with custom minting, vesting, and governance. - DeFi Primitives: Automated Market Makers (AMMs), lending pools, staking mechanisms, and yield aggregators.
- Enterprise Logic: Multi-signature wallets, access control systems, and complex business workflows on-chain.
We deliver battle-tested contracts with a focus on security and maintainability, reducing your time-to-audit by 60%.
Our engineers use established patterns from OpenZeppelin and follow formal verification practices. Every contract includes detailed documentation, a full test suite, and deployment scripts for EVM-compatible chains like Ethereum, Polygon, and Arbitrum.
Technical & Commercial Questions
StarkNet Migration FAQs
Get clear answers on timelines, costs, and technical details for migrating your smart contracts from Solidity to Cairo on StarkNet.
Our standard migration timeline is 2-4 weeks from kickoff to mainnet deployment, depending on contract complexity. A simple token or basic DeFi module takes 2 weeks. A full DEX or lending protocol with 10-20 core contracts typically requires 3-4 weeks. This includes audit preparation, testing on testnet, and final deployment.
