Imagine that you want to trade tokens on Uniswap or buy an NFT on OpenSea, but your crypto wallet and these DApps are like "friends" living on different planets, unable to communicate directly due to language barriers. @undefined $WCT #WalletConnect Just like a talented "translator," by scanning a QR code or clicking a link, your wallet and DApp can connect seamlessly, establishing a secure connection in an instant. @undefined Founded in 2018, created by founder Pedro Gomes. This open-source protocol has evolved from being "unknown" to connecting over 700 wallets (such as MetaMask, Trust Wallet) and 67,000 DApps (such as PancakeSwap, Aave), making it a "super hub" in the Web3 world. As of 2025, it has facilitated 337 million connections, serving 50 million independent active wallets, covering numerous blockchains such as Ethereum, Solana, and Polkadot. This record is truly impressive! Its working principle is simple yet efficient: users open the DApp, choose the WalletConnect connection method, scan the QR code or click the link, and the wallet and DApp "hold hands" through an encrypted channel, allowing users to authorize transactions, sign or view data, all in a seamless and secure manner. Even more impressive is that @WalletConnect connections are end-to-end encrypted, and the "messenger" (relay server) in between can only pass the package, unable to peek at the contents, achieving true security without any leaks.
