Core Privacy & Security Features
We build mobile wallets with security-first architecture, ensuring user assets and data are protected by design. Our development process integrates battle-tested cryptographic libraries and rigorous audit practices.
04
Real-Time Threat Detection
Embedded behavioral analytics and signature scanning to detect phishing attempts, malicious DApps, and anomalous transaction patterns. We integrate threat feeds to block interactions with known malicious contracts in real-time.
06
Compliance-Ready Privacy
Build with privacy-preserving compliance tools like zero-knowledge KYC (e.g., zkKYC) and audit trails for regulated entities. Our architecture supports selective disclosure to verifiers without exposing underlying user data.

PROVEN METHODOLOGY
Our Development & Delivery Process
We deliver production-ready mobile privacy wallets in 8-12 weeks using our battle-tested, security-first development lifecycle designed for FinTech compliance and user adoption.
01
Discovery & Architecture
We conduct a 2-week technical deep-dive to define wallet architecture, select optimal privacy protocols (e.g., ZK-SNARKs, stealth addresses), and create a detailed spec for MPC key management and on-chain interactions.

Architecture Questions
02
Secure Core Development
Our engineers build the wallet core using React Native/Flutter with native modules for secure enclave operations. We implement MPC/TSS for key generation, integrate privacy layers like Tornado Cash Nova, and develop custom RPC nodes for data shielding.

Security Model
03
Security Audits & Pen Testing
Every component undergoes rigorous internal review followed by third-party audits. We test for front-running vulnerabilities, side-channel attacks on key storage, and simulate real-world threat scenarios before launch.

04
Staging & User Testing
We deploy to a private TestFlight/Play Console for controlled beta testing. We gather UX feedback on transaction flows, simulate high-gas scenarios, and validate backup/recovery processes under real network conditions.

Technical & Commercial Questions
Mobile Privacy Wallet Development FAQs
Answers to the most common questions from CTOs and product leads evaluating a custom privacy wallet build. Based on our experience delivering 30+ secure wallet applications.
A production-ready MVP with core privacy features (e.g., stealth addresses, private transactions) typically deploys in 6-10 weeks. This includes architecture, development, internal security review, and integration with your backend. Complex multi-chain deployments or advanced ZK-proof integrations can extend to 12-16 weeks. We provide a detailed sprint-by-sprint roadmap after the initial discovery phase.
