The Mission
“To build a best-in-class, multi-chain crypto wallet as a Chrome browser extension — giving users a secure, feature-rich gateway to DeFi that simplifies portfolio management, token swaps, and dApp connectivity.”
Core Objectives
- Multi-chain account management from a single master seed phrase
- In-browser token swaps and cross-chain swap capabilities
- Hardware wallet support for power users (Ledger, Trezor)
- Social and NFT features for a next-generation wallet experience
The Challenge
At the time of development, dominant browser wallets offered bare-bones UX — no built-in swaps, no NFT browsing, no social layer. Aurox needed to serve both crypto-native power users and newcomers from within the strict constraints of a Chrome extension popup, where every interaction had to be fully functional in a small, fixed viewport.
The product roadmap was aggressive: alpha by end of July 2022, full MVP (chains, NFTs, swaps, transaction history) by mid-August. A separate contractor team was building the native mobile wallet simultaneously, requiring feature parity alignment. Hardware wallet integration (Ledger and Trezor) added protocol-level complexity within the extension environment.
What We Built
Multi-Chain Wallet Core
BIP44 master seed phrase derivation across all supported blockchain types, with full account management, transaction history, and send/receive flows in a compact Chrome extension popup.
Token Swaps & Cross-Chain
In-app token swap functionality with THORChain integration explored for cross-chain swaps — bringing exchange-level capabilities directly into the browser wallet.
Hardware Wallet & ENS Support
Ledger and Trezor integration with varied derivation path handling, plus ENS-based address management (username.aurox.eth) for simplified identity across chains.
NFT Portfolio & Social Features
NFT portfolio viewing with marketplace interactions, Lens Protocol profile detection, followed-address transaction feeds, and fiat on-ramp integrations (Wyre, Circle) for direct fiat-to-DeFi flows.
Technical Architecture
Chrome browser extension built on React with BIP44 multi-chain key derivation, wallet connection protocols for Ledger and Trezor, and Web3 provider injection for dApp compatibility. UI constrained to a popup format — every feature had to function within fixed dimensions. Coordinated via shared Figma boards and Notion with Aurox's internal product and research team.
Real Impact.
Aurox Wallet delivered a comprehensive multi-chain Chrome extension wallet with BIP44 key derivation, hardware wallet support, token swaps, NFT browsing, and social features — all within the constraints of a browser popup.
