Keyra - Multi-Chain Crypto Wallet App UI/UX (Expo)

Description:

Keyra is a modern multi-chain crypto wallet UI/UX designed with a focus on clarity, usability, and visual consistency. It provides a clean, intuitive interface for creating and managing wallets across multiple blockchain networks, ideal for projects that value simplicity and a polished user experience.

The app supports 9 blockchain networks, including Ethereum, BNB Chain, Polygon, Arbitrum, Base, Tron, and Solana, with a focus on secure wallet generation, seamless network switching, and clear asset visualization.

Tokens are loaded automatically via smart contracts, ensuring accurate portfolio data and a structured asset view without manual configuration.

Built with a UI/UX-first approach, Keyra delivers a simple, reliable, and everyday-ready wallet experience.

FAQ:

Q: Which networks does Keyra support?
A: Ethereum, Ethereum Sepolia, BSC, Polygon, Optimism, Arbitrum, Base, Tron, Solana.

Q: Can I create and recover wallets easily?
A: Yes, Keyra allows fast wallet creation and secure recovery with a 12-word mnemonic phrase. You can restore your wallet anytime on any device without losing access to your funds.

Q: Can I add custom tokens?
A: Absolutely, you can add any ERC-20/BEP-20 token by entering the token contract address. Keyra makes token management simple and fast.

Q: How do I switch between networks?
A: You can switch networks with a single tap within the wallet interface, allowing you to manage assets across Ethereum, BNB Chain, and Polygon seamlessly.

Q: Is my data secure?
A: Keyra is designed according to strict security standards. Private keys never leave the app and are never stored in the state manager. All sensitive data is securely handled, ensuring full protection of your assets. Redux Persist and encrypted local storage are used only for safe, non-sensitive state data.

Q: Was Keyra built with scalability in mind?
A: Yes, Keyra was developed with a modular and scalable architecture using NestJS for the backend and clean, well-structured React Native components for the frontend. This design allows easy expansion with new networks, tokens, or features in the future without compromising performance or security.

Q: Does Keyra include an admin panel?
A: No, Keyra is a decentralized application (dApp). It does not have an admin panel and does not allow anyone to view or access users’ private keys. All wallet operations and sensitive data remain fully under the user’s control, ensuring maximum security and decentralization.

Q: How can Keyra be monetized?
A: By default, Keyra does not include any built-in monetization. However, developers can optionally integrate monetization features such as premium services, in-app subscriptions, affiliate links with exchanges or DeFi platforms, or token-based incentives. These options are fully optional and do not compromise user security or control over private keys.

Q: How many tokens does Keyra support by default?
A: Keyra supports over 45 popular tokens across multiple networks out of the box. This list can be easily expanded, allowing you to add more tokens at any time.

Q: What happens if the app supports over 2000 tokens? Will it cause any problems or slow down the app?
A: No, the number of tokens does not affect usability or performance. Keyra is designed to manage only the tokens that the user actually interacts with. Tokens that the user does not use are not loaded or processed, ensuring the app remains fast and responsive even with thousands of tokens available.
