PROVEN PROCESS
Our Delivery Methodology
We deliver production-ready EVM Mobile Controller SDKs through a structured, transparent workflow designed for speed, security, and seamless integration.
01
Discovery & Architecture
We start with a technical deep-dive to map your specific use case—be it DeFi, gaming, or enterprise—to the optimal EVM architecture. We define the SDK's scope, required wallet integrations (MetaMask, WalletConnect), and key performance indicators.

Frequently Asked Questions
Answers to common technical and commercial questions about our SDK for embedding secure, non-custodial wallets into mobile applications.
For a standard integration with a single EVM chain (e.g., Ethereum, Polygon, Arbitrum), you can expect a production-ready implementation in 2-3 weeks. This includes setup, core wallet features (send/receive, token swaps), and basic UI customization. Complex multi-chain deployments or advanced DeFi integrations may extend this to 4-6 weeks. We provide a detailed project plan during the initial technical scoping call.
