WalletConnect is not a standalone application but an open-source protocol that enables decentralized applications (dApps) to establish secure connections with cryptocurrency wallets. It creates an encrypted link between dApps, wallets, or devices, ensuring data privacy and security.
How to Use WalletConnect
Connecting a crypto wallet to a dApp is straightforward with WalletConnect. You can:
- Scan a QR Code: Use your mobile wallet to scan the dApp’s QR code.
- Deep Linking: Connect directly via a desktop wallet.
For example, you can link a WalletConnect-compatible wallet like MetaMask or Trust Wallet to Aave, a popular DeFi platform for lending and borrowing crypto.

Is WalletConnect Safe?
WalletConnect employs end-to-end encryption for all shared data between dApps and wallets:
- A unique symmetric key is exchanged only between the two parties.
- Data passes through a public bridge server, but the server cannot decrypt it.
- Developers can opt for private bridge servers for added security.
Key Safety Notes:
- WalletConnect never accesses your seed phrase.
- Connections require explicit wallet approval.
