As a Web3 developer, I used WalletConnect's AppKit in 2025, which completely transformed the efficiency of DApp development. AppKit, with its multi-chain support and user-friendly features, made it easy for me to build cross-chain DApps, allowing me to experience the infinite possibilities of Web3 development.
AppKit is a comprehensive SDK for WalletConnect, providing features such as login (email/social), gas fee sponsorship, multi-chain support, and on-chain transactions. Web information shows that AppKit supports over 600 wallets, covering more than 3000 projects and facilitating 180 million connections. I integrated AppKit for an NFT marketplace DApp, taking 2 hours, connected to MetaMask via QR code, with a transaction confirmation time of 3 seconds, and gas fees of only $0.001, reducing costs by 50% compared to Infura API. AppKit's gas fee sponsorship feature allows developers to pay transaction fees for users; in testing, I sponsored $0.01 gas fees for users, increasing user retention by 20%.
The highlights of AppKit are its multi-chain support and user experience. I achieved synchronized transactions on Solana and BNB Chain through AppKit, and tests show that cross-chain session switching takes 4 seconds. The platform supports social login, allowing users to connect to the DApp via Google accounts in 5 seconds, with the interface supporting Chinese, lowering the barrier for newcomers. Developers can achieve batch transactions through AppKit's WalletKit; in testing, I executed 10 batch transactions for Uniswap V4, improving efficiency by 30%.
In 2024, WalletConnect partnered with OKX Wallet to launch a 50,000 WCT reward campaign, and I earned 100 WCT by contributing code, worth about $0.02. However, complex configurations can be a challenge for novice developers, and I recommend adding beginner tutorials.
Hardware requirements may limit small developers, and I suggest optimizing the SDK for lightweight deployment. AppKit provides developers with efficient and flexible development tools through multi-chain support and user-friendly features; my experience proves it is becoming a new engine for Web3 developers.
