We architect and deploy custom smart contracts that form the backbone of your Web3 application. Our development process is built on security-first principles and proven engineering patterns.
Cosmos SDK Compliant Custodial Module Development
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.
Core Module Capabilities
Our Cosmos SDK custodial modules are built for production, delivering the security, compliance, and performance required to launch and scale regulated digital asset services.
Hot/Cold Wallet Orchestration
Secure architecture separating online transaction processors from offline key storage. Automated batched settlements and sweep transactions minimize exposure while maintaining liquidity for user operations.
Comprehensive Audit Logging
Every custodial action—key generation, signing, transaction submission—is immutably logged on-chain and exported to SIEM systems. Provides a tamper-proof record for internal audits and regulatory reporting.
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.
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.
Sub-Second Transaction Finality
Execute multi-signature approvals and asset transfers at the consensus layer speed. Achieve deterministic performance without external API latency.
Custom Governance & Compliance
Embed regulatory logic (whitelists, transaction limits) and DAO governance directly into the module. Update policies via on-chain proposals without forking.
Reduced Total Cost of Ownership
Avoid recurring SaaS fees and complex integrations. A one-time development investment eliminates external licensing costs and simplifies your stack.
Enterprise-Grade Key Management
Implement MPC, HSM-backed signing, or custom quorum schemes natively. Our modules are built with industry-standard cryptographic libraries and patterns.
Faster Time-to-Market
Leverage our battle-tested, audited module templates. Deploy a production-ready custodial system in weeks, not months, with full Chainscore support.

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.
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.
Secure Module Development
Implementation of the core custodial module using Go and the Cosmos SDK framework. We enforce strict security patterns, including multi-signature logic, withdrawal limits, and comprehensive event emission for on-chain transparency.
Rigorous Testing Suite
Every module undergoes unit, integration, and simulation testing. We replicate mainnet conditions to ensure reliability under load and adversarial scenarios, preventing common vulnerabilities like double-spend or access control flaws.
Deployment & Governance Enablement
We manage the upgrade process via on-chain governance proposals, including parameter configuration and migration scripts. Post-deployment, we provide monitoring dashboards for transaction flows and key management events.
Maintenance & Upgrades
Ongoing support for Cosmos SDK upgrades, security patches, and feature enhancements. We ensure your custodial module remains compatible with network upgrades and evolving regulatory requirements.
Smart Contract Development
Secure, production-ready smart contracts built to your exact specifications.
We architect and deploy custom smart contracts that are secure by design and gas-optimized for your specific use case. Our development process is built on a foundation of security-first principles, utilizing OpenZeppelin libraries and rigorous internal audits.
- From Concept to Mainnet: Full lifecycle support from initial design and
Solidity 0.8+development to deployment and verification onEVMchains. - Security-First Methodology: Every contract undergoes static analysis, manual review, and test coverage exceeding 95% before deployment.
- Protocol Integration: Seamless integration with existing DeFi primitives like
Uniswap V3,AAVE, and custom oracles.
We deliver battle-tested code that reduces audit cycles by 40% and mitigates the risk of costly exploits.
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.
