overview
CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built for scale and compliance.

We architect and deploy custom smart contracts that form the backbone of your Web3 application. Our development process is built on security-first principles, utilizing OpenZeppelin libraries and rigorous internal audits before deployment on EVM or Solana.

  • Full Lifecycle Development: From initial architecture to deployment and upgrade management using Transparent or UUPS proxy patterns.
  • Security & Auditing: Every contract undergoes formal verification and is prepared for third-party audits by firms like CertiK or Trail of Bits.
  • Gas Optimization: We deliver contracts with up to 40% lower gas costs through efficient storage patterns and assembly-level optimization where required.

We deliver battle-tested contracts that power DeFi protocols, NFT marketplaces, and enterprise-grade applications with 99.9% uptime SLAs.

Our team specializes in complex logic for DeFi (AMMs, lending/borrowing, yield strategies) and digital assets (ERC-20, ERC-721, ERC-1155). We ensure your contracts are future-proof with upgradeability and clear ownership controls.

CORE SERVICE

Smart Contract Development

Secure, audited smart contracts built for production by blockchain-native engineers.

We architect and deploy custom smart contracts on EVM and Solana that form the secure backbone of your application. Our development process is built on OpenZeppelin standards and includes comprehensive unit and integration testing before any line of code is audited.

  • Production-Ready Code: Built with Solidity 0.8+ or Rust, following established security patterns and gas optimization techniques.
  • Multi-Stage Security: Every contract undergoes internal review, automated analysis (Slither, MythX), and a formal audit by a third-party firm.
  • Full Lifecycle Support: From initial design and deployment to upgradeability planning and post-launch monitoring via our dashboard.

Frequently Asked Questions

Get clear, technical answers about our SDK development, deployment, and support process.

A standard EVM Smart Account Abstraction SDK with core features (ERC-4337 bundler/paymaster integration, multi-chain support, key management) is typically delivered in 4-6 weeks. Complex customizations, like novel signature schemes or proprietary gas sponsorship logic, can extend this to 8-10 weeks. We provide a detailed project plan with weekly milestones after the initial scoping call.
