Non-Custodial & MPC Key Architecture
Distributed key sharding (TSS) eliminating seed phrase friction while preserving full self-custody.
Threshold Signatures (MPC/TSS)
Private keys are never assembled in full; shards are distributed across user device, cloud, and backup.
Hardware Enclave Integration
Apple Secure Enclave and Android TEE storing cryptographic seeds with biometric auth.
ERC-4337 Smart Accounts
Native account abstraction enabling social login, automated subscription payments, and sponsored gas.
Decentralized DEX Aggregator
In-wallet token swaps routed through 1inch and Jupiter for optimal pricing and minimal slippage.
What We Deliver
Clear architectural boundaries, automated test suites, and 100% intellectual property transfer on day one.

Frequently Asked Technical Questions
Common architectural, governance, and codebase ownership inquiries.
In an MPC wallet, the private key never exists in a single location. Instead, cryptographic key shares are distributed across your device and secure servers, enabling seamless recovery without requiring users to write down a 12-word seed phrase.
