CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built for scale and compliance.
- End-to-End Development: From initial concept and
Solidity/Rustcoding to deployment and mainnet verification. - Security & Audits: Mandatory peer review and integration with tools like
SlitherandMythX. We prepare contracts for third-party audits. - Gas Optimization: Every contract is optimized for minimum gas consumption, reducing end-user transaction costs by up to 40%.
- Upgradeability Patterns: Implementation of secure proxy patterns (
ERC-1967,Beacon) for future-proof, non-custodial upgrades.

PROVEN FRAMEWORK
Our Delivery Methodology
We deliver production-ready RWA sub-wallet infrastructure through a structured, transparent process designed for security and speed. Our methodology ensures you go from concept to launch with zero operational overhead.
01
Architecture & Design Sprint
We conduct a 2-week collaborative sprint to define your tokenization logic, custody model, and compliance requirements. This phase establishes the technical blueprint and smart contract architecture for your RWA-linked wallets.

Technical and Commercial FAQs
Get clear answers to the most common questions about our technical approach, security, timelines, and commercial terms for building compliant sub-wallet infrastructure.
A standard deployment for a compliant, multi-chain sub-wallet infrastructure takes 4-6 weeks from kickoff to mainnet launch. This includes smart contract development, integration with your core platform, security audits, and a pilot phase. For projects requiring complex RWA-specific logic (e.g., legal wrapper integration, KYC/AML hooks), timelines extend to 8-12 weeks. We provide a detailed, phase-gated project plan at the outset.
