WalletConnect adopts a "relay server + symmetric encryption" model: Users establish an encrypted session channel with the DApp by scanning the QR code generated by the DApp on their wallet. All communications are relayed through the relay server, but the data is encrypted by the symmetric key generated by both parties, with the private key always stored locally to avoid leakage risks. Chain agnostic and multi-chain support

As a "chain agnostic" protocol, WalletConnect is not tied to a specific blockchain and supports EVM chains (Ethereum, Polygon, etc.) and non-EVM chains (Solana, Cosmos, etc.). Users can connect to multiple chain wallets simultaneously, enabling one-click switching and cross-chain interaction, reducing operational complexity. $WCT #WalletConnect @WalletConnect
