Wallet Standard

A chain-agnostic TypeScript interface specification (maintained at github.com/wallet-standard/wallet-standard) that defines how browser-based wallets register themselves, expose supported features, and implement signing operations via a globally discoverable window object. On Solana, wallets implement the Solana-specific feature set (solana:signTransaction, solana:signMessage, etc.), allowing any compliant dApp using Wallet Adapter to enumerate and use installed wallets without hard-coded wallet detection logic.
