CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built to your exact specifications.
- Full Lifecycle Development: From initial design and
Solidity/Rustcoding to deployment and on-chain verification. - Security Audits: Every contract undergoes rigorous internal review and is prepared for third-party audits using OpenZeppelin standards.
- Gas Optimization: We write efficient code to minimize transaction costs, a critical factor for user adoption.
- Integration Ready: Contracts are built to seamlessly connect with your front-end and backend systems.
We deliver battle-tested contracts for tokens (
ERC-20,ERC-721), DeFi protocols, DAOs, and more, ensuring your project launches on a foundation of reliability and trust.

ARCHITECTURAL ADVANTAGES
Why Build a Native Custodial Module
Integrating a native module directly into your Cosmos SDK blockchain provides foundational security, performance, and control that external solutions cannot match.
01
Sovereign Security Model
Maintain full control over your custody logic and private keys. Eliminate reliance on third-party black boxes and their associated attack surfaces.

PROVEN METHODOLOGY
Our Development & Integration Process
A structured, security-first approach to delivering production-ready, compliant custodial modules that integrate seamlessly with your existing Cosmos SDK chain.
01
Architecture & Specification
We begin with a deep technical assessment of your chain's consensus, governance, and tokenomics to design a modular custody solution. Deliverables include a detailed technical specification, threat model, and integration roadmap.
2-3 Days
Initial Design Sprint

Frequently Asked Questions
Get clear answers on our development process, timelines, security, and support for your custom custodial solution.
A standard, production-ready custodial module deployment typically takes 4-6 weeks from kickoff to mainnet launch. This includes 1 week for design & specification, 2-3 weeks for core development and unit testing, and 1-2 weeks for security audit integration and final deployment. Complex features like multi-sig governance or cross-chain asset support can extend the timeline, which we scope and agree upon upfront.
