Wallet v7.3.1 Released, Added New Watch-Only Mode

Overview

As a leading multi-chain wallet and Web3 gateway, this wallet platform is committed to providing a secure and user-friendly environment for accessing the decentralized world. The release of version 7.3.1 introduces a comprehensive suite of new features and upgrades designed to enhance user experience significantly. This update includes the integration of Starknet, a revolutionary watch-only wallet mode, and the reimplementation of NFT purchasing capabilities with any token.

The security infrastructure has been substantially upgraded to support hardware wallets, ensuring that users can manage their assets with maximum protection. Additionally, a strategic partnership with Certik provides an extra layer of security verification for user assets, demonstrating the platform's commitment to safeguarding digital holdings in the evolving Web3 landscape.

Four New Mainnets Added: Find Even Better Deals on Swap

To further extend the ecosystem of multi-chain interoperability, this update adds four significant mainnets: Starknet, Sui Devnet, Shardeum Liberty 2.X, and Conflux eSpace. The inclusion of Starknet marks a particularly important milestone, as it represents the fourth ZK (Zero-Knowledge) mainnet to be integrated into the multi-chain ecosystem. This addition demonstrates continued progress in contributing to Ethereum's Layer 2 scaling solutions, addressing the critical need for faster and more cost-effective transactions.

With these new chains, the platform now supports over 90 mainnets, encompassing six major ecosystems: EVM, Non-EVM, Cosmos, Move, and Bitcoin. This extensive coverage ensures that users can interact with virtually any blockchain network from a single interface. After updating to the latest version, users gain the ability to add and manage assets across all new mainnets, enabling seamless interaction with the expanding multi-chain ecosystem.

The Swap feature, which remains the platform's most essential functionality, has been enhanced alongside Ethereum V2 integration. This enhancement delivers a smoother transaction experience and more competitive pricing through an exclusive DEX aggregator. The aggregator technology scans multiple decentralized exchanges simultaneously to identify the best available rates, ensuring users receive optimal value for their trades.

Furthermore, the DApp browser now aggregates futures contract trading from a major exchange platform, eliminating the need for users to complete KYC procedures. This integration provides a more comprehensive on-chain futures trading experience with freely adjustable leverage multipliers, giving users greater flexibility in their trading strategies while maintaining the security and privacy advantages of decentralized platforms.

Added Watch-Only Wallet

This update introduces an innovative feature called "Watch-Only Wallet," which fundamentally changes how users can monitor blockchain addresses without compromising security. When importing a wallet, users now have the option to select "watch-only" mode and simply enter the corresponding wallet address, without any need to import sensitive private keys.

A Watch-Only wallet operates on a fundamentally different principle from regular wallets. It requires only a public address, allowing users to monitor the asset balance and transaction history of a specific address without having the ability to interact with or transfer the assets. In this mode, no private key is stored on the user's device, ensuring maximum security. Users can view asset balances and transaction records in real-time and receive push notifications when new transactions occur, but cannot execute any transfers from a Watch-Only wallet.

This new Watch-Only mode perfectly complements the multi-chain interoperability ecosystem, supporting the importation of addresses from over 90 mainnets. The versatility of this feature makes it valuable for various use cases in the cryptocurrency space.

There are two primary scenarios for utilizing Watch-Only wallets:

1. Cold Wallet Management: Users can monitor the status of their asset balances without importing private keys or mnemonic phrases online. This approach is ideal for cold wallet management, where the private keys remain completely offline and secure, while users can still track their holdings conveniently through the Watch-Only interface.

2. Smart Money Tracking: Users can monitor specific smart contracts or other addresses of interest. For example, many cryptocurrency enthusiasts track the public addresses of crypto whales and prominent Web3 key opinion leaders (KOLs) to gain valuable insights into market movements and investment strategies. Through Watch-Only mode, users can easily track and monitor the activities of these influential addresses 24/7, learning from their trading patterns and asset allocation decisions.

It is crucial to understand that users have no control over Watch-Only wallets. When transferring assets, users must carefully verify the target address and confirm private key ownership. Never mistakenly transfer assets to Watch-Only wallets that are outside your control, as you will be unable to retrieve those assets without the corresponding private key. This feature is designed solely for monitoring purposes and does not grant any transaction capabilities.

Revamped Functionality: Purchase NFT with Any Token

The NFT market functionality has been significantly enhanced with integration across multiple networks, including Optimism, enabling users to access essential functions such as display, transfer, transaction execution, and comprehensive data analytics. The platform reintroduces an innovative feature called "Purchase NFT with Any Token," which was originally launched at an early stage and has now been fully revamped for improved performance.

When trading NFTs on Ethereum or various Layer 2 public chains such as Polygon, Arbitrum, and Optimism, users often encounter a common challenge: insufficient ETH in their wallet to complete the transaction. The traditional approach requires exchanging ERC20 tokens for ETH to purchase an NFT, but this process presents difficulties in accurately calculating the total cost of the purchase plus gas fees. Users typically end up with small, unusable amounts of leftover ETH, which represents an inefficient use of capital.

To address this issue, the platform unifies token and NFT transactions, dramatically simplifying user operations and reducing overall transaction costs. By allowing users to pay for NFTs directly with any token they hold, the platform eliminates the need for intermediate conversion steps. This feature extends beyond Ethereum to the BNB Chain, where users can purchase NFTs with any BEP20 token, as well as all other public chains supported by the NFT marketplace.

The process is straightforward: After selecting the desired NFT in the marketplace, users can switch to their preferred payment token on the purchase page. The platform automatically handles the token conversion in the background, enabling seamless payment with any token held in the wallet. This innovation significantly improves the user experience and makes NFT trading more accessible to a broader audience.

Integrate Hardware Wallets Like Keystone

This version places significant emphasis on security enhancements, introducing comprehensive hardware wallet integration to provide users with enterprise-grade asset protection. The platform has integrated hardware wallets supporting multiple connection protocols, including QR code connections and Bluetooth, ensuring compatibility with various devices and user preferences.

The mobile version now supports mainstream hardware wallets such as Keystone, among others. This integration represents a major step forward in providing non-network solutions for managing wallet assets, achieving an optimal balance between security and convenience. Hardware wallets store private keys in a secure, offline environment, protecting them from potential online threats such as hacking attempts, phishing attacks, and malware.

By connecting a hardware wallet to the platform, users can approve transactions securely while keeping their private keys completely isolated from internet-connected devices. This approach significantly reduces the attack surface and provides peace of mind for users managing substantial cryptocurrency holdings.

In addition to hardware wallet integration, the platform has established a partnership with Certik for comprehensive security audits of related smart contracts, including the Swap functionality and NFT Market contracts. This collaboration follows a previous partnership with SlowMist, demonstrating the platform's commitment to maintaining the highest security standards through multiple independent audits.

The product line now encompasses web terminals, browser plug-in extensions, and mobile applications, each offering a consistent and secure user experience. Every version upgrade and experience optimization reflects the dedication of the development team, who actively listen to user feedback and continuously refine the product. Users are encouraged to provide feedback on any issues encountered or suggestions for improvement, as this input directly shapes the platform's evolution.

Important Upgrade Reminder

Before updating to version 7.3.1, users should take essential precautions to ensure the safety of their assets. Please back up all wallet data, store mnemonic phrases and private keys offline in a secure location, and download the product upgrade only through official channels. These steps are crucial for maintaining the security and accessibility of your digital assets throughout the update process.
