CORE SERVICE
Smart Contract Development
Secure, audited smart contract development for DeFi, NFTs, and enterprise applications.
- Security Audits: Every contract undergoes internal and third-party review before deployment, following OpenZeppelin standards.
- Gas Optimization: We write efficient code to reduce user transaction costs by up to 40%.
- Full-Stack Integration: Seamless connection to your front-end via
ethers.jsorweb3.js. - Protocol Expertise:
ERC-20,ERC-721,ERC-1155,ERC-4626, and custom logic for DeFi, DAOs, and marketplaces.
Deliver a secure, audited, and gas-optimized smart contract suite in as little as 4 weeks, from specification to testnet deployment.
