CrossX Wallet Extension - Technical Documentation
1. Project Overview
CrossX is a browser-based wallet extension designed to facilitate native coin transactions across CrossFi and EVM-compatible blockchains. It supports essential wallet functionalities such as sending and receiving native coins, managing ERC-20 tokens and NFTs, and secure private key management through a 12-word seed phrase. CrossX aims to create an interoperable, secure, and user-friendly wallet that bridges the gap between various decentralized ecosystems, providing users with full control over their digital assets.
2. Key Features
2.1. 12-Word Seed Phrase Security
CrossX uses a 12-word seed phrase to generate private keys, ensuring user account security. The wallet securely stores and encrypts these seed phrases, allowing users to recover their wallets if necessary.
2.2. CrossFi and EVM-Compatible Support
CrossX provides built-in support for native coin transactions on the CrossFi blockchain, as well as EVM-compatible chains like Ethereum. It enables seamless token transfers between different blockchains without requiring users to switch between multiple wallets.
2.3. ERC-20 and NFT Management
The wallet can fetch balances for ERC-20 tokens and manage NFTs where applicable, giving users a complete view of their on-chain assets.
2.4. Transaction Handling
CrossX supports sending coins to any EVM-compatible address and provides clear visibility into transaction fees and details before submission. The wallet’s intuitive interface ensures users can execute transfers with minimal friction.
2.5. Encryption and Private Key Management
Private keys and sensitive data, such as the seed phrase, are encrypted using industry-standard algorithms. This ensures that sensitive information is stored securely and prevents unauthorized access.
