Transaction UX and Application State

Construct and submit a program transaction based on user input from the UI.

Provide UI feedback for transaction submission, confirmation, and error states.

Integrate a client-side caching library (e.g., SWR or React Query) to manage fetching and caching of on-chain data.

Implement a global state management solution (e.g., Zustand or React Context) for wallet and user data.

Design and implement a state machine to model the lifecycle of a transaction (e.g., composing, signing, sending, confirmed).

Handle transaction submission errors from the wallet or RPC and display user-friendly feedback.

Implement optimistic UI updates for a smoother user experience while waiting for transaction finalization.
