CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built to your exact specifications.
- Token Systems:
ERC-20,ERC-721, andERC-1155with custom minting, vesting, and governance logic. - DeFi Protocols: Automated Market Makers (AMMs), staking pools, and yield aggregators.
- Enterprise Logic: Multi-signature wallets, access control, and upgradeable proxy patterns for future-proofing.
Every contract undergoes rigorous internal review and is structured for seamless integration with leading audit firms like CertiK or Quantstamp, ensuring security is foundational, not an afterthought.

BUILT FOR REGULATORY CERTAINTY
Core Technical Capabilities
Our StarkNet Cairo development delivers immutable, verifiable data trails that meet stringent compliance requirements. We build with security-first principles and enterprise-grade architecture.
02
Immutable Audit Trail Architecture
We design state models that permanently record every transaction, KYC check, and compliance event on-chain. This creates a tamper-proof, chronological ledger that regulators can verify independently, eliminating data disputes.

Frequently Asked Questions
Get clear answers on our process, timelines, and technical approach for building secure, auditable compliance data trails on StarkNet.
A standard implementation takes 4-8 weeks from kickoff to mainnet deployment. This includes 1-2 weeks for requirements and architecture, 2-4 weeks for Cairo smart contract development and internal testing, and 1-2 weeks for audit preparation and deployment. Complex integrations with existing KYC/AML systems or custom zero-knowproof logic can extend this timeline, which we scope and quote for upfront.
