Why Choose
Why Choose Junkies Coder for Wallet Development
WHY CHOOSE
As a dedicated Cryptocurrency Wallet Development company, we offer several key advantages:
Security-First, Non-Custodial Architecture
Wallet security is non-negotiable. We build solutions based on the non-custodial principle, ensuring private keys are generated, encrypted, and stored client-side only (on the user's device). Our core focus is on implementing advanced security features like Multi-Signature (Multi-Sig) controls, secure key vault integrations (like Android Keystore/iOS Secure Enclave), and rigorous cryptographic best practices to protect assets from theft and fraud.
Mobile-Native Expertise (iOS & Android)
As a proven mobile app development company, Junkies Coder excels at creating high-performance, native mobile wallets. We leverage deep expertise in Kotlin/Java for Android and Swift/Objective-C for iOS, ensuring your app feels seamless and utilizes built-in hardware security features like Biometric Authentication (Face ID/Touch ID) for an optimal user experience.
Future-Proof Multi-Chain & Web3 Integration
The decentralized landscape is multi-chain. We don't limit you to one network. We develop true multi-chain wallets that seamlessly support Bitcoin, Ethereum, Solana, and custom tokens (ERC-20, etc.). Furthermore, we integrate essential Web3 protocols like WalletConnect and built-in dApp browsers, positioning your wallet as a powerful, versatile portal to the entire DeFi and NFT ecosystem.
Cost-Optimized Development from India
Hiring specialized in-house crypto developers is costly and time-consuming. By outsourcing to Junkies Coder in India, you gain access to a dedicated team of certified blockchain and mobile experts instantly. This strategic cost-efficiency ensures you receive world-class quality, rapid development speed, and dedicated technical support at a fraction of the cost of typical Western agencies.

How We Develop
Our 6-Step Cryptocurrency Wallet Development Process
OUR PROCESS
We guide your project through a transparent, security-audited process to ensure the final wallet is robust, user-friendly, and compliant.
#1 Strategy, Scope & Architecture
We define the project's purpose: Will it be a mobile-first DeFi wallet, an enterprise Multi-Sig solution, or a Web3 browser extension? This phase locks down the target audience, the necessary core features (send/receive/swap), the specific blockchain networks to support (multi-chain selection), and the crucial choice between custodial, non-custodial, or MPC architecture.
#2 UI/UX Design & Prototyping
A complex crypto wallet must feel simple. Our designers focus on creating an intuitive, secure user flow. We map out every interaction—from generating the Seed Phrase to signing a transaction—to minimize user error and maximize trust. We deliver detailed wireframes and high-fidelity prototypes for your approval before any code is written.
#3 Security & Key Management Implementation
Security is implemented before functionality. This critical step involves coding the secure non-custodial key generation (BIP-39), ensuring keys are encrypted and stored locally (e.g., using the device's secure enclave), and integrating primary security layers like Multi-Factor Authentication (MFA) and Biometrics (Face ID/Touch ID).
#4 Core Development & Blockchain Integration
Our developers build the application using the chosen tech stack (e.g., Swift/Kotlin for Native, React Native/Flutter for cross-platform). We integrate Web3 libraries (like Ethers.js) and connect the wallet's backend to the various blockchain nodes via reliable RPC providers, enabling real-time balance checks and secure transaction broadcasting.
#5 Rigorous Testing & Security Audits
Testing a wallet is paramount due to the immutability of funds. We conduct comprehensive testing: Functional Testing: Verifying transactions, swaps, and dApp connections work flawlessly. Performance Testing: Checking speed and stability under network load. Security Testing: Performing penetration testing and vulnerability scans to find and patch any potential weak points before launch.
#4 Deployment, Compliance & Ongoing Support
We manage the final deployment to app stores (Apple App Store / Google Play Store) and the mainnet, ensuring compliance with all platform guidelines. Post-launch, Junkies Coder provides continuous monitoring, maintenance, and mandatory security patches to ensure your wallet remains functional, safe, and up-to-date with evolving blockchain standards.

FAQ's
Find clarity on everything you need to know.
How do you guarantee the security and non-custodial nature of the wallet?
We ensure true security by strictly adhering to the non-custodial principle. This means Junkies Coder never has access to the user’s private keys; they are generated, encrypted, and stored locally on the user’s device (e.g., in a secure enclave). Our process involves mandatory Multi-Factor Authentication (MFA), Biometric Security (Face/Touch ID), and rigorous security audits before final deployment to prevent unauthorized access and theft.
What is a Multi-Signature (Multi-Sig) wallet, and do I need one?
A Multi-Signature wallet is an advanced security feature that requires approval from a predefined number of private keys (e.g., 2 out of 3 keys) to authorize any transaction. You typically need one if you are a business, DAO, or institution managing significant treasury funds, as it eliminates any single point of failure (e.g., one lost or compromised key) and enforces internal governance. We specialize in custom Multi-Sig setups.
What is the estimated cost and time to build a custom crypto wallet?
The cost and timeline depend on complexity (single vs. multi-chain, basic features vs. DeFi integration). A basic wallet might start at $30,000 and take 3-6 months. However, by choosing Junkies Coder in India, you benefit from a significantly lower development hourly rate ($30-$70/hr) compared to Western firms ($100-$200/hr), allowing you to build a feature-rich, high-quality product at a more strategic and competitive price point.
Which blockchains can you integrate into the wallet?
We offer platform-agnostic development. We can integrate any major public blockchain, including Ethereum (EVM-compatible chains), Solana, Bitcoin, Polygon, and Avalanche, ensuring your wallet is a versatile tool for managing all popular cryptocurrencies and tokens (ERC-20, NFTs, etc.). We focus on building seamless multi-chain capabilities from a single, unified user interface.
