React-Native EVM Wallet Build

Job ID: 39805359

Budget: $250 – $750 USD

I have all the screens designed and need a developer who can turn them into a fully-functional mobile EVM wallet, built with React Native (Expo). The goal is to release a first build in one week, so I’m looking for someone comfortable sprinting from day one.

Core scope
• Users must be able to send and receive ERC-20/721/1155 tokens, view a full transaction history, and switch between multiple on-chain accounts derived from the same seed phrase.
• Both manual token import and automatic detection should work seamlessly.
• A simple price chart for any selected token has to render inside the asset view (you can consume a public API of your choice; just keep calls lightweight).
• Dapp connectivity is handled through WalletConnect v2; once a session is approved, signing and transaction prompts need to follow the native MetaMask pattern.
• App security relies on a password at startup plus biometric unlock (Touch ID / Face ID on iOS, fingerprint on Android).

Technical notes
I’m already set up with Expo Go, so the project should run without ejecting. Please stick to TypeScript, ethers.js, expo-secure-store for key material, and the latest WalletConnect SDK. If you see a better library for a specific feature, flag it early.

We will guide the project on Metamask Wallet and it's features.

Deliverables
1. Git repo containing clean, documented code matching the designs.
2. Test build (Android & iOS) delivered via Expo.
3. One short Loom walkthrough so I can verify flows before we push to TestFlight / Play Console.

Acceptance criteria
• All listed features operate smoothly on both platforms.
• No private keys or seed phrases leave the device; encryption follows best practices.
• App boots in under two seconds on mid-range hardware.

I’ll be available every day for quick feedback. If you have recent wallet or DeFi work, send a link when you apply—otherwise a concise plan of attack is perfect.
