Smart wallet auth

Description and Related Issue(s)

Resolves #3159

This PR implements smart wallet authentication using Dynamic (WaaS - Wallet as a Service) as an alternative to the existing Auth0-based authentication. The implementation allows users to authenticate using their connected wallet through Dynamic's smart wallet infrastructure, providing a seamless Web3 authentication experience.

The changes include integration of Dynamic SDK, refactoring of user profile components to support multiple auth providers, dynamic imports for web3 wallet packages to optimize bundle size, and updates to the wallet connection flow to work with smart wallets. The implementation maintains backward compatibility with the existing Auth0 authentication while adding the new Dynamic provider as an option.

Proposed Changes

• Smart wallet authentication integration: Added Dynamic (WaaS) provider support for user authentication using connected wallets
• Auth provider abstraction: Refactored user profile components to support multiple authentication providers (Auth0 and Dynamic)
• Dynamic imports: Implemented code splitting for web3 wallet packages to reduce initial bundle size
• Wallet connection improvements: Enhanced wallet connection flow to support smart wallets and improved reconnection handling
• User profile refactoring: Reorganized user profile components into separate directories for auth0 and dynamic providers, with shared common utilities

Environment Variables

• NEXT_PUBLIC_ACCOUNT_AUTH_PROVIDER: Selects the authentication provider (auth0 or dynamic) for basic user authentication. Defaults to auth0 for backward compatibility
• NEXT_PUBLIC_ACCOUNT_DYNAMIC_ENVIRONMENT_ID: Environment ID of the Dynamic project, required when using dynamic as the auth provider
• NEXT_PUBLIC_RE_CAPTCHA_APP_SITE_KEY: Updated to be required only when using auth0 as the provider (previously always required)

Breaking or Incompatible Changes

No breaking changes. The implementation maintains full backward compatibility with existing Auth0 authentication. The new Dynamic provider is opt-in via environment variable configuration.

Additional Information

This implementation is part of the WaaS pilot program. More details can be found in the related Notion document referenced in issue #3159.

Note

High Risk
Touches core authentication and wallet-connection flows and introduces a new third-party provider path (Dynamic) plus top-level-await-based code splitting, which could impact login/connectivity and runtime bundling if misconfigured.

Overview
Adds an opt-in Dynamic (WaaS) authentication + wallet connector path alongside the existing Auth0/Reown setup, controlled by new envs (NEXT_PUBLIC_ACCOUNT_AUTH_PROVIDER, NEXT_PUBLIC_ACCOUNT_DYNAMIC_ENVIRONMENT_ID) and a new account.authProvider/blockchainInteraction.connectorType feature payload.

Refactors web3/auth plumbing to switch providers via top-level await import(...) code-splitting: introduces Web3Provider that selects ReownProvider vs DynamicProvider, adds Dynamic-specific useWallet/useAccount hooks, updates CSP to be connector-aware, and adjusts UI entry points (profile button, auth guards, email-linking, address verification) to route through Auth0 vs Dynamic. Also adds a general:auth_dynamic API resource, manual gas estimation for Dynamic contract writes, disables rewards when using Dynamic, and updates build/test configs (higher Node memory, enable top-level await, TS target ES2017, browser sourcemaps off, Playwright CT env bootstrap).
