Mobile Wallet with Built-In Proof Generation
We engineer mobile wallets that generate Zero-Knowledge proofs locally on the user's device. This architecture reduces external dependencies, accelerates transaction finality, and places data sovereignty directly in the user's hands.

Architectural Comparison
On-Device Proof Generation vs. Traditional Architecture
A technical breakdown comparing the security, performance, and user experience of our mobile-native proof generation against conventional server-based wallet architectures.
| Architecture Factor | Traditional Server-Based Wallets | Chainscore Mobile Wallet (On-Device Proofs) |
|---|---|---|
Proof Generation Location | Centralized Server | User's Mobile Device |
Private Key Exposure | High (transmitted to server) | Zero (never leaves device) |
User Onboarding Friction | High (KYC, deposits) | Low (non-custodial, instant) |
Transaction Latency | 500ms - 2s (network hops) | < 100ms (local computation) |
Offline Capability | None (requires server) | Partial (proof generation) |
Server Infrastructure Cost | $10K - $50K/month | < $1K/month (orchestration only) |
Regulatory Attack Surface | Large (custodial entity) | Minimal (non-custodial) |
Time to Implement | 3-6 months (full stack) | 4-8 weeks (SDK integration) |
Proof Verification Cost | High (on-chain) | Negligible (off-chain, ZK-verified) |
Recommended For | Custodial exchanges, simple apps | FinTechs, DeFi, Gaming, Privacy-first apps |
