A comprehensive set of four self-contained example applications demonstrating the Sphere Connect protocol for integrating dApps with the Sphere wallet. The examples cover a browser dApp (React/Vite), a Node.js CLI dApp over WebSocket, an autonomous bot that runs its own wallet (direct SDK, no Connect), and a backend-auth flow where a frontend brokers a wallet signature and a backend verifies it cryptographically to issue a JWT. The codebase is a multi-package monorepo, each package pinned to the same SDK version (0.14.2), with extensive test coverage, CI/CD, and detailed documentation. The overall architecture is clean and well-structured, exhibiting high engineering craftsmanship in areas like money-safety (duck-typed detection of possibly-committed sends), exact string-based unit conversion, and byte-exact challenge reconstruction for signature verification.
