Wallet Connect
An open-source protocol and SDK enabling seamless, secure wallet connections to 70K+ decentralized apps across blockchains.
Overview
WalletConnect is a widely adopted open-source protocol and software development kit (SDK) that enables secure and seamless connections between decentralized wallets and blockchain applications. It acts as a connectivity layer for the financial internet, facilitating billions of dollars in value transfer monthly. WalletConnect supports over 700 wallets and more than 70,000 decentralized apps, making it one of the most extensive ecosystems for wallet interoperability. The protocol is powered by a decentralized network of 20+ node operators, ensuring high availability and security.
The core WalletConnect SDK offers developers a streamlined integration to enable wallet connections with minimal technical overhead. It supports one-click authentication, secure transaction signing, phishing protection, and advanced on-chain features such as batch transactions and paymasters. WalletConnect is trusted by custodial, self-custody, mobile, and hardware wallets, providing a unified gateway to on-chain applications across multiple blockchains.
WalletConnect recently evolved into Reown, expanding its product suite with AppKit, a comprehensive SDK for building seamless on-chain user experiences including login, gas fee sponsorship, multi-chain support, swaps, and user insights. Developers can get started quickly using open-source SDKs, detailed documentation, and example implementations available on GitHub. WalletConnect’s ecosystem also includes WalletGuide, a directory and certification standard for high-quality on-chain wallets. With millions of users and a daily network volume exceeding $1.5 billion, WalletConnect remains a foundational infrastructure tool for Web3 developers and enterprises aiming to integrate wallet connectivity efficiently.
