We architect and deploy custom smart contracts that form the secure, immutable backbone of your application. Our development process is built on audited security patterns and a deep understanding of gas optimization for cost-effective on-chain operations.
Mobile Institutional-Grade Custody Solutions
Smart Contract Development
Secure, production-ready smart contracts built by Web3 experts to power your protocol.
- Full-Stack Development: From
ERC-20tokens andERC-721NFTs to complex DeFi logic and DAO governance systems. - Security-First Approach: Code reviews, automated testing with
Hardhat/Foundry, and integration with top audit firms. - Production Focus: Contracts are built for mainnet deployment with upgradeability patterns, pausability, and comprehensive event logging.
We deliver battle-tested contracts that reduce your time-to-market by weeks and provide a foundation trusted by users and auditors.
Core Infrastructure Features
Our mobile-first custody platform is engineered with institutional-grade security and operational resilience, enabling you to manage digital assets with the same confidence as traditional finance.
Multi-Party Computation (MPC) Wallets
Eliminate single points of failure with our proprietary MPC architecture. Private keys are never stored in full, providing superior security to traditional seed phrases or HSMs while maintaining full self-custody.
Policy-Based Transaction Signing
Enforce granular, role-based governance with configurable approval workflows. Set multi-signature rules, transaction limits, and whitelists directly from the mobile interface for complete operational control.
Cross-Chain Asset Support
Securely custody and manage assets across 30+ leading blockchain networks including Ethereum, Solana, Polygon, and Bitcoin, all within a unified mobile interface. No fragmented wallets required.
Compliance & Audit Trail
Automated, immutable logging of all custody actions for internal audit and regulatory compliance. Generate detailed reports for transaction history, user activity, and policy changes on demand.
Hot-Warm-Cold Architecture
Dynamically allocate assets across security tiers based on liquidity needs. Maintain instant access to operational funds in hot wallets while securing the majority of assets in offline, air-gapped cold storage.
Business Outcomes for Your Mobile Product
Deploy a mobile custody solution that meets institutional standards for security and compliance while delivering a seamless user experience. Our architecture is built for scale and trust.
Regulatory Compliance & Audit Trail
Multi-jurisdictional compliance frameworks (FINRA, SEC, MiCA-ready) with immutable, real-time audit logs for all transactions and key management events.
Institutional-Grade Security
MPC-based key management with distributed signing ceremonies. Hardware Security Module (HSM) integration and biometric authentication ensure assets are protected at rest and in transit.
Sub-Second Transaction Finality
Optimized transaction batching and gas management for Ethereum, Polygon, and Solana, delivering fast, cost-effective settlements directly from mobile.
Scalable Multi-Chain Architecture
Native support for 15+ blockchains (EVM, Solana, Cosmos) with a unified API. Add new chain support in days, not months, without app updates.
White-Label Branding & SDK
Fully customizable UI/UX SDKs for iOS and Android. Maintain your brand identity while we handle the complex custody infrastructure.
Enterprise SLAs & 24/7 Monitoring
Guaranteed 99.95% uptime SLA with dedicated engineering support. Real-time threat detection and automated incident response protocols.

Our Development & Integration Process
A structured, security-first approach to deliver a production-ready custody solution that integrates seamlessly with your existing tech stack and compliance workflows.
Architecture & Security Design
We design a multi-layered security architecture using MPC/TSS technology, hardware security modules (HSMs), and a clear separation of duties. This ensures your private keys are never exposed, meeting institutional security requirements from day one.
Core Wallet & API Development
Our team builds the core custody engine with support for 50+ assets, multi-signature policies, and a comprehensive REST API. We deliver a white-labeled mobile SDK for iOS and Android, enabling seamless user onboarding and transaction signing.
Compliance & Audit Integration
We integrate mandatory compliance features, including transaction monitoring for AML/CFT, customizable allow/deny lists, and full audit trail generation. The system is designed to plug into your existing compliance tools and reporting frameworks.
Staging & Penetration Testing
Before launch, your solution undergoes rigorous testing in a production-like staging environment. We conduct internal audits and partner with leading firms like Halborn or CertiK for independent penetration testing and smart contract reviews.
Production Deployment & Handoff
We manage the deployment to your cloud infrastructure (AWS/GCP/Azure) with zero-downtime strategies. You receive full documentation, operational runbooks, and knowledge transfer sessions for your DevOps and security teams.
Ongoing Support & Monitoring
Post-launch, we provide 24/7 infrastructure monitoring, alerting, and dedicated technical support. Our team offers ongoing maintenance, security patch management, and feature updates based on protocol upgrades.
Mobile Institutional Custody: Key Questions
Technical and operational details for teams evaluating secure, mobile-first custody infrastructure.
Standard deployment takes 2-4 weeks from kickoff to production-ready. This includes MPC key infrastructure setup, mobile SDK integration, and security hardening. Complex multi-chain or custom policy requirements can extend this to 6-8 weeks. We provide a detailed project plan in the initial technical scoping session.
Smart Contract Development
Secure, production-ready smart contracts built for scale and compliance.
We architect and deploy custom smart contracts that power your token, DeFi, or NFT platform. Our development process ensures security-first design, gas optimization, and full audit readiness from day one.
- Token Systems:
