CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built for scale and compliance.
Deliver a battle-tested, gas-optimized contract suite in 2-4 weeks, not months.
Our full-service development includes:
- Token Systems: Custom
ERC-20,ERC-721, andERC-1155implementations with minting, vesting, and governance modules. - DeFi Protocols: Automated Market Makers (AMMs), staking pools, yield aggregators, and lending/borrowing logic.
- Enterprise Logic: Multi-signature wallets, access control systems, and compliant asset tokenization frameworks.
- Full Audit Support: Code is structured and documented for seamless third-party security audits.
We don't just write code; we ensure it performs. Every contract is optimized for gas efficiency and designed for future upgrades, protecting your long-term operational costs and product roadmap.

TANGIBLE ROI
Business Outcomes for Archival Institutions
Our Cosmos SDK AppChain delivers measurable results for archives, libraries, and cultural heritage organizations. Move beyond proof-of-concept to a production-ready, cost-effective decentralized archive.
01
Immutable, Tamper-Proof Record
We implement a sovereign blockchain where each data hash is permanently anchored to the Cosmos Hub, creating an immutable, court-admissible chain of custody for digital artifacts. Eliminate disputes over provenance and authenticity.
100%
Provenance Integrity
IBC-Enabled
Cross-Chain Verification
02
Radical Cost Reduction
Replace expensive centralized storage and manual verification with a decentralized network. Our AppChain architecture slashes long-term archival costs by distributing storage and validation across participating institutions.

Compliance Audits
03
Global Collaborative Curation
Enable multi-institutional governance for shared collections. Our custom modules allow partner archives to propose, vote on, and verify additions to the chain, fostering unprecedented collaboration without a central authority.

Our Development & Deployment Process
A structured, four-phase framework designed to deliver a production-ready, secure, and scalable Cosmos SDK AppChain for decentralized archiving. We focus on rapid iteration, transparent communication, and guaranteed outcomes.
01
Architecture & Design Sprint
We conduct a 2-week intensive sprint to define your chain's consensus model, tokenomics, and archival data structure. This phase establishes the technical blueprint and security architecture, ensuring your AppChain meets specific archival requirements for data integrity and retrieval.

Core Chain Development
Our team builds your custom Cosmos SDK module for data anchoring, implements Inter-Blockchain Communication (IBC) for cross-chain proofs, and develops the archival node software. All code follows Cosmos best practices and includes comprehensive unit and integration testing.

Security Audit & Testnet Deployment
Your AppChain undergoes a rigorous security audit by a third-party firm. We then deploy to a public testnet, conducting load testing for high-throughput data ingestion and coordinating a bug bounty program to identify vulnerabilities before mainnet launch.

Frequently Asked Questions
Get clear answers on timelines, costs, and technical details for building a decentralized archiving solution.
A production-ready, minimum viable AppChain with core archiving modules (data anchoring, storage proofs, governance) typically deploys in 6-8 weeks. Complex features like custom IBC channels or advanced tokenomics can extend this to 10-12 weeks. We follow a phased delivery model with weekly sprints and milestone reviews.
