CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3 specialists.
Deliver a battle-tested, auditable codebase in weeks, not months.
Our expert team handles the full lifecycle:
- Architecture & Design: Logic specification and gas optimization planning.
- Development: Implementation in
Solidity/RustusingOpenZeppelinlibraries. - Security: Rigorous internal review and integration with leading audit firms.
- Deployment & Verification: Mainnet launch with full transparency on
Etherscan.
We mitigate critical risks:
- Reentrancy & overflow vulnerabilities eliminated through proven patterns.
- Upgradeability via transparent proxy patterns (
UUPS/Beacon). - Gas cost reduction of 15-40% through optimized logic and storage.

PROVEN METHODOLOGY
Our Development Process
We deliver secure, production-ready encrypted file sharing protocols through a structured, transparent process designed for technical founders and CTOs. From initial architecture to final audit, our focus is on security, scalability, and your time-to-market.
01
Architecture & Protocol Design
We design the core cryptographic protocol and system architecture, selecting optimal primitives (e.g., AES-256-GCM, ECIES) and blockchain frameworks (IPFS, Arweave, Filecoin) for your specific threat model and performance requirements.

02
Smart Contract & Core Logic
Development of immutable access control, key management, and payment logic using Solidity 0.8+ or Rust. We implement gas-optimized patterns and OpenZeppelin libraries to ensure security from the ground up.

SECURE BY DESIGN
Technology & Protocol Foundation
Our encrypted file sharing protocols are built on a bedrock of proven, audited technology. We deliver production-ready foundations that prioritize security, scalability, and developer experience from day one.
04
Access Control Smart Contracts
Custom ERC-721/1155 or ERC-5564-based contracts that manage granular permissions, subscriptions, and token-gated access. Enforce business logic for sharing, revocation, and audit trails.
05
End-to-End Encryption (E2EE) Protocols
Implement industry-standard encryption (AES-256-GCM, XChaCha20-Poly1305) with secure key derivation. Client-side encryption ensures data is never exposed to servers in plaintext.
