ARCHITECTED FOR INSTITUTIONS
Core Technical Capabilities
Our modular Account Abstraction stack is built to meet the stringent security, compliance, and performance demands of institutional capital. We deliver production-ready infrastructure, not just concepts.
01
Multi-Party Computation (MPC) Wallets
Deploy institutional-grade smart contract wallets with configurable multi-signature policies, transaction batching, and social recovery. Eliminate single points of failure for seed phrases and private keys.

Architectural Comparison
Traditional Custody vs. Programmable Smart Accounts
A technical breakdown of legacy custody models versus modern, programmable smart account solutions for institutional digital asset management.
| Feature / Metric | Traditional Custody | Programmable Smart Accounts (ERC-4337) |
|---|---|---|
Asset Control Model | Custodian-held private keys | User-owned smart contract logic |
Transaction Authorization | Manual, multi-sig approvals | Programmable rules & multi-factor auth |
Automation Capability | Limited, API-dependent | Native (scheduled payments, auto-compounding) |
Gas Fee Management | Manual, user-paid | Sponsored or paid in any ERC-20 token |
Recovery Mechanisms | Lengthy legal/KYC process | Social recovery via guardians |
Integration Complexity | High (custom APIs, whitelists) | Low (standard EIP, wallet-as-a-service) |
Time to New Feature | Months (vendor roadmap) | Weeks (deploy new contract module) |
Typical Setup Time | 4-8 weeks | 2-4 weeks |
Annual Operational Cost | $50K - $200K+ | $15K - $75K (infra + maintenance) |

Account Abstraction for Institutions
Frequently Asked Questions
Get clear answers on how we deliver secure, scalable account abstraction infrastructure for institutional portfolios.
Security is our primary design constraint. We implement a multi-layered approach: smart contracts are built with Solidity 0.8+ and OpenZeppelin libraries, undergo formal verification and audits by firms like Spearbit, and integrate with institutional custody solutions (Fireblocks, Copper). We enforce role-based multi-signature policies, session key management with strict limits, and real-time threat monitoring. All deployments include a comprehensive security review and a 90-day post-launch bug bounty period.
