Imagine you want to use a blockchain application (DApp) on your computer, but your crypto assets are stored in your mobile wallet. How can you securely allow them to 'talk' to each other? This is where WalletConnect comes into play.

2. What is WalletConnect

WalletConnect is an open-source protocol, acting as a secure communication bridge, allowing different blockchain wallets (especially mobile ones) to easily and securely connect to various decentralized applications (DApps), regardless of whether the DApp runs on a computer browser, mobile phone, or tablet.

3. Core principles: Secure QR code connection

1. Initiate connection: Select WalletConnect for login/operations on the DApp, which generates a QR code or connection link.

2. Scan to authorize: Open a trusted mobile wallet (such as MetaMask Mobile, Trust Wallet, etc.), scan the QR code or click the link.

3. Establish encrypted channel: After scanning, an end-to-end encrypted channel is established between the wallet and DApp, with the private key always remaining in the user's wallet; WalletConnect does not touch or store private keys and assets.

4. Operation confirmation: Operations that require wallet confirmation on the DApp (transactions, signatures, etc.) are sent to the mobile wallet through the encrypted channel, allowing for review and confirmation in the wallet, ensuring security and convenience.

4. Importance and problems it solves

- Compatibility: One protocol connects a multitude of supported wallets and DApps without the need for individual app adaptations.

- Security: End-to-end encryption ensures communication security, with the private key never leaving the user's hands, reducing the risk of leakage.

- User experience: Eliminate the hassle of copying and pasting addresses and repeatedly switching apps for authorization; just scan once, and subsequent operations can be completed in a familiar and secure wallet environment.

- Cross-platform: The phone acts as a keychain, easily unlocking Web3 applications on computers and tablets.

5. Common application scenarios

- Trade on DeFi/NFT platforms like Uniswap and OpenSea on the computer web version, confirming with the mobile wallet scan.

- Play blockchain games that require wallet interaction on the web.

- Participate in DAO governance voting.

- Log in to Web3 websites that support WalletConnect.

6. Summary

WalletConnect is a key infrastructure of the Web3 ecosystem that builds secure connections through QR code scanning, solving the interoperability challenges between wallets and DApps, allowing users to conveniently and securely manage their crypto assets and identities across different devices. Next time you see its option on a DApp, you might want to give it a try. #WalletConnect $WCT @WalletConnect
