CORE SERVICE

Smart Contract Development

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

We architect and deploy audited, gas-optimized smart contracts on EVM and Solana. Our development process ensures security-first design, comprehensive testing, and maintainable code from day one.

  • Custom Logic: ERC-20, ERC-721, ERC-1155, custom DeFi primitives, and DAO governance.
  • Security Audits: Integration with leading firms like CertiK and OpenZeppelin.
  • Deployment & Verification: Full-stack support from local testnets to mainnet launch on Ethereum, Polygon, Arbitrum, or Solana.

Reduce your time-to-market from months to weeks with our battle-tested development framework.

We deliver production-ready contracts with:

  • Formal verification for critical financial logic.
  • Upgradeability patterns using transparent proxies.
  • Gas optimization reports to minimize user transaction costs by 15-40%.
  • Comprehensive documentation and developer handoff.

Technical & Compliance Questions

FAQ: Compliant Deletion-Resistant Archives

Get clear answers on how we design, deploy, and maintain blockchain-based archives that meet stringent data protection regulations like GDPR and CCPA.

We architect systems where personal data is never stored directly on-chain. Instead, we use a hybrid model: off-chain encrypted data vaults (with client-held keys) linked to immutable, anonymized pointers on-chain. Deletion requests trigger the secure destruction of the off-chain encryption keys, rendering the personal data permanently inaccessible, while preserving the integrity of the on-chain audit trail. This satisfies regulatory deletion requirements without compromising the blockchain's immutability.
