Privacy-Preserving Zero-Knowledge Spending Limits
We implement custom zk-SNARK or zk-STARK circuits to enforce and prove spending limits and policy adherence within sub-accounts, without revealing underlying transaction details to the parent account or network.

CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3-native engineers.
We architect and deploy custom smart contracts that are secure, gas-optimized, and tailored to your specific business logic. Our process ensures your on-chain application is built on a robust and auditable foundation from day one.
From concept to mainnet, we deliver contracts you can stake your business on.
- Full-Stack Development: End-to-end contract systems using
Solidity/Vyperon EVM chains (Ethereum,Polygon,Arbitrum) orRust/Moveon Solana/Aptos. - Security-First Approach: Development follows OpenZeppelin standards and includes comprehensive unit/integration testing before formal audits.
- Key Deliverables: Deployable contract suite, technical documentation, and a 2-week MVP turnaround for standard token or NFT projects.

Frequently Asked Questions
Get clear answers on our development process, security, and implementation for your ZK-powered compliance solution.
A standard implementation for a single protocol (e.g., a DEX or lending pool) takes 2-4 weeks from kickoff to mainnet deployment. This includes design, circuit development, smart contract integration, and security review. Complex multi-protocol integrations or custom compliance logic may extend to 6-8 weeks. We provide a detailed project plan during the initial technical scoping call.
