PROVEN FRAMEWORK
Our Development & Security Methodology
A structured, security-first approach that delivers production-ready mobile wallets in weeks, not months. We combine battle-tested engineering with rigorous security protocols to ensure your application is robust, scalable, and secure from day one.
01
Secure Architecture & Threat Modeling
We design wallet architectures using industry standards like BIP-32/39/44 for key derivation and implement secure enclave/keystore integration. Every project begins with a formal threat model to identify and mitigate risks before a single line of code is written.

02
Gas-Optimized Smart Contract Integration
Our engineers write and audit custom smart contract interactions (ERC-20, ERC-721, DeFi protocols) using Solidity 0.8+ and OpenZeppelin libraries. We focus on minimizing gas costs and ensuring fail-safe transaction handling for a seamless user experience.

Frequently Asked Questions
Get clear answers on timelines, costs, and technical specifics for your mobile wallet project.
For a standard white-label EVM wallet with core features (multi-chain support, token/NFT management, secure key storage, basic swaps), we deliver a production-ready MVP in 4-6 weeks. Complex customizations (advanced DeFi integrations, MPC key management, custom UI/UX) can extend this to 8-12 weeks. We provide a detailed sprint-by-sprint roadmap after the initial discovery phase.
