How WalletConnect Works

At its foundation, WalletConnect acts as a communication layer that enables wallet applications to interact with DApps without exposing sensitive information, such as private keys.

The protocol supports encrypted messaging through a session established by scanning a QR code or clicking a deep link. Once connected, users can approve or reject transactions directly from their wallets, which remain in their full control throughout the session.

WalletConnect supports multiple blockchain networks, including Ethereum, Solana, Cosmos, Polkadot, and Bitcoin.

WalletConnect is built on three key pieces:

Network: This is the system of nodes that pass messages between your wallet and the app you're using. These nodes are run by different groups to keep things decentralized.

SDKs: Developers use WalletConnect SDKs to add the connection feature to their wallets and DApps. The SDKs handle all the technical stuff behind the scenes.

Standards: WalletConnect uses standard rules for how messages are sent and received, which makes it easier for apps and wallets to work together smoothly.
