Wallet Adapter

A TypeScript/JavaScript library maintained by Solana Labs (now under the Anza umbrella) that provides a unified interface and React context for connecting to and interacting with browser extension wallets (Phantom, Backpack, Solflare, etc.) using the Wallet Standard. It abstracts wallet-specific APIs behind a common connect/disconnect/signTransaction/sendTransaction interface, allowing dApps to support all compliant wallets without custom per-wallet integration code.
