METHODICAL & SECURE
Our Development & Integration Process
A proven, end-to-end framework for building and deploying enterprise-grade encrypted storage protocols on EVM chains, designed for security, speed, and seamless integration.
01
Architecture & Design Review
We analyze your data privacy requirements and design a custom protocol architecture. This includes selecting optimal encryption schemes (e.g., ECIES, AES-GCM), defining key management flows, and planning gas-efficient storage patterns on your target EVM chain (Ethereum, Polygon, Arbitrum).

Smart Contract Development
Our engineers write, test, and optimize Solidity/Vyper contracts for core protocol logic, access control, and encrypted data handling. We implement industry standards (ERC-725, ERC-734) where applicable and use OpenZeppelin libraries for foundational security.

CORE SERVICE
Smart Contract Development
Secure, audited smart contracts built to your exact specifications.
We deliver production-ready smart contracts in Solidity 0.8+ and Rust, following OpenZeppelin standards and formal verification practices. Our code is built for security first, ensuring your protocol's logic is immutable and resilient.
- Custom Tokenomics:
ERC-20,ERC-721, andERC-1155implementations with vesting, minting, and governance modules. - DeFi Primitives: Automated Market Makers (AMMs), lending pools, staking systems, and yield aggregators.
- Enterprise Logic: Multi-signature wallets, access control, upgradeable proxy patterns, and cross-chain bridges.
Every contract undergoes rigorous security audits and gas optimization before deployment, reducing vulnerabilities and operational costs.
Deliverables include: Fully documented source code, deployment scripts, a comprehensive audit report, and a 2-week MVP timeline for standard implementations.

Frequently Asked Questions
Get clear answers on our development process, security, and timelines for building your confidential on-chain data solution.
A standard EVM encrypted storage protocol MVP with core features (key management, encryption/decryption, basic access control) typically deploys in 4-6 weeks. Complex systems with custom zero-knowledge proofs, multi-chain support, or advanced governance can take 8-12 weeks. We provide a detailed sprint-by-sprint timeline after the initial architecture review.
