CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3 experts for your protocol or application.
- Protocol Development: Launch your own
ERC-20,ERC-721, or custom token standard with tailored economics. - DeFi & DEX: Build automated market makers (AMMs), liquidity pools, staking, and yield-farming contracts.
- NFT Ecosystems: Create dynamic collections with advanced minting, royalties, and utility layers.
- Enterprise Logic: Implement complex multi-signature wallets, governance (
ERC-20/ERC-721), and access control systems.
We deliver audit-ready code from day one, using
Solidity 0.8+,Hardhat/Foundry, andOpenZeppelinlibraries to ensure security and reduce time-to-audit.
Our end-to-end service includes comprehensive testing, deployment scripting, and mainnet launch support. We focus on delivering gas-efficient, secure contracts that scale, so you can launch with confidence.

PROVEN PROCESS
Our Development & Audit Methodology
A rigorous, multi-stage approach designed to deliver secure, production-ready encrypted data stream contracts with predictable timelines and guaranteed outcomes.
01
Architecture & Specification
We begin with a collaborative design session to define your data flow, encryption schema (e.g., ECIES, AES-GCM), and on-chain/off-chain boundaries. This phase establishes clear requirements and a technical blueprint, preventing costly revisions later.
1-2 days
Workshop
Zero revisions

Secure Implementation
Development in Solidity 0.8+ using OpenZeppelin libraries and custom encryption logic. We implement gas-optimized patterns for data batching and event emission, ensuring your streams are cost-effective at scale.

Comprehensive Auditing
Every contract undergoes a multi-layered security review: automated analysis with Slither, manual line-by-line review by our senior auditors, and scenario testing for edge cases in data encryption and access control.

Frequently Asked Questions
Get clear answers on our process, security, and delivery for encrypted data stream smart contracts.
A standard encrypted data stream contract with core features (on-chain verification, key management, event emission) takes 2-3 weeks from spec to mainnet deployment. Complex integrations (multi-chain, custom oracles, advanced access control) extend this to 4-6 weeks. We provide a detailed sprint plan within the first week of engagement.
