WalletConnect: The Invisible Infrastructure Connecting the Web3 World
In Web3, wallets are not just tools for storing assets, but gateways to user identity. WalletConnect, as an open-source connection protocol, is building a bridge between DApps and wallets. You may not have used its official website, but many DApps you are familiar with, such as Uniswap and OpenSea, are largely powered by it.
What is WalletConnect?
WalletConnect is a communication protocol for connecting DApps with mainstream wallets (like MetaMask, Trust Wallet, etc.). Users can securely interact with web-based DApps through mobile wallets simply by scanning a QR code or clicking a link, without the need to disclose private keys or install plugins.
It can be understood as the “Bluetooth protocol” of Web3—it doesn’t store assets but enables secure conversations between wallets and applications.
Core Advantages
✅ Cross-platform Interoperability: Seamless connection between computers and mobile devices, enhancing user experience
🔐 High Security: End-to-end encrypted communication, with signatures completed only in the local wallet
🔄 Multi-chain Support: The V2 version supports multi-chain sessions (such as Ethereum, Polygon, BNB, Arbitrum, etc.)
🧩 Extensive Ecosystem: Adopted by over 2000 DApps, it is the most mainstream connection protocol in Web3
WalletConnect V2: Moving Towards a Decentralized Session Layer
The V2 version brings multi-chain and multi-session support, a more unified URI standard, a more stable Relay network, and on-chain push notification functionality (integrating Push/Waku protocols). WalletConnect is transitioning from a “connection tool” to a “decentralized session layer.”
Ecosystem Development
WalletConnect has received multiple rounds of funding (from USV, Coinbase, 1kx, etc.) and is laying out new infrastructure such as WalletConnect Cloud, identity systems (DID), and on-chain notifications, becoming an indispensable connector in Web3.
Summary
WalletConnect does not issue tokens or create chains, but serves as the “water, electricity, and gas” driving the usability of Web3. It enables true interoperability between wallets and DApps, making the on-chain experience simpler and safer for ordinary users. @WalletConnect
