Exploring the Technical Principle Analysis of @WalletConnect 🤖🔥
#WalletConnect ($WCT ) serves as a cross-device wallet connection protocol designed to enable users to conveniently and securely operate cryptocurrency wallets across different terminals (such as mobile and desktop). A typical application scenario involves a mobile wallet application (Wallet App) connecting to a desktop decentralized application (DApp) through Wallet Connect to complete wallet operation authorization.
From a technical perspective, #WalletConnect essentially functions as a 'Remote Ethereum Wallet Provider', responsible for handling standard JSON-RPC requests and responses. When users initiate transaction signing or other wallet operation requests on the DApp side, these requests are relayed via the Relay Server provided by #WalletConnect . The Relay Server utilizes WebSocket for real-time bidirectional communication, securely forwarding requests to the user's wallet application. After the user confirms or rejects the operation on the wallet side, the result is also encrypted and returned to the DApp through the same channel.
The entire transmission process employs end-to-end encryption mechanisms to ensure that messages are not intercepted or tampered with during the relay process, safeguarding user asset security and privacy.
In June 2025, #WalletConnect officially upgraded from version 1 to version 2. The biggest technical breakthrough of this version lies in expanding support from only Ethereum Virtual Machine (EVM) compatible chains to multi-chain support, including non-EVM ecosystems such as Polkadot and Cosmos. The new protocol further abstracts the interface design, allowing developers to more flexibly integrate various public chain wallets, promoting interoperability in the cross-chain ecosystem.
