Cross-Net
A Multi‑Chain Wallet for Seamless dApp Connectivity
The problem Cross-Net solves
Cross‑Net addresses the fragmentation in the blockchain wallet ecosystem. Today, users struggle with having separate wallet apps and inconsistent connection flows across dApps. With Cross‑Net, users can:
Connect and disconnect their wallet easily,
Select networks (supporting both mainnet and testnet environments) with a simple UI,
Import tokens manually, and
View portfolio balances at a glance from a unified dashboard.
In addition, Cross‑Net lets users switch wallets on the fly, ensuring that whether you’re on Ethereum, Tron, Solana, or any other supported network, your wallet experience remains seamless. On mobile, our solution goes further by acting as an integrated web3 browser—meaning users can connect to dApps directly through the extension without opening a separate wallet app (similar to Trust Wallet). This unified approach enhances security, usability, and interoperability across different blockchain ecosystems.
Challenges we ran into
EIP‑1193 Integration: Implementing a compliant provider that dApps can interact with was non‑trivial. We had to build a robust messaging system between the background service worker and content scripts to securely relay requests.
Multi‑Chain Support: Supporting non‑EVM chains (like Tron and Solana) meant integrating different SDKs (tronWeb and solana/web3.js) and normalizing their APIs to work with our core logic.
Asynchronous Event Handling: Ensuring that wallet connection, network switching, and account changes emit the correct events to dApps required careful orchestration and thorough testing across various browsers.
Mobile Browser Integration: Building a built‑in web3 browser (so users don’t need a separate wallet app) was challenging due to differences in mobile CSP and browser extension capabilities. We overcame these hurdles by modularizing our code and leveraging manifest V3 features.
