WalletConnect is a connectivity protocol and SDK ecosystem for linking wallets, applications, and blockchain networks. It helps apps request wallet connections, signatures, transactions, and sessions across web and mobile experiences.

Use it for:

• Letting users connect supported wallets to DApps.
• Maintaining wallet sessions across devices and interfaces.
• Supporting wallet verification and app metadata.
• Building wallet compatibility without custom integrations for every wallet.

Best fit: application and wallet teams that need broad, production-ready wallet connectivity across supported chains.
