PRIVACY BY DESIGN
Core SDK Capabilities We Deliver
Our Rollup Privacy SDK provides the foundational tooling to build confidential, compliant, and scalable applications. We deliver production-ready modules, not just theoretical concepts.
03
Developer Tooling & Local Sandbox
A full local development environment with privacy-preserving RPC nodes, forked networks, and debugging tools. Test private transactions end-to-end with the same toolchain used for public chains, reducing integration time by 70%.

Faster Integration
05
Gas-Optimized Privacy Circuits
Pre-built and audited ZK circuits for common operations (private transfers, balances, voting). Our circuits are optimized for specific rollup provers (e.g., RISC Zero, SP1), reducing proof generation costs by up to 40% versus generic implementations.

CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3-native engineers.
We architect and deploy custom smart contracts that form the backbone of your protocol. Our development process is built on security-first principles, utilizing OpenZeppelin libraries and comprehensive audit workflows to mitigate risk before mainnet deployment.
From tokenomics to governance, we translate your business logic into immutable, efficient code.
- Token Systems:
ERC-20,ERC-721,ERC-1155with custom minting, vesting, and staking logic. - DeFi Primitives: Automated Market Makers (AMMs), lending pools, yield aggregators, and derivative contracts.
- Gas Optimization: Code reviews and optimization to reduce transaction costs by up to 40% for your users.
- Full Lifecycle Support: Development, testing (
Hardhat/Foundry), auditing, and mainnet deployment management.
