<p>The sudden appearance of an "invalid JSON-RPC" error is usually a node glitch. The useDApp contracts might be "paused" during critical maintenance. The official project documentation is the best place to find advanced troubleshooting guides.</p>

<p>Sometimes a simple delay in block finality can make a successful tx appear as if it failed. Reviewing the contract's read-only functions can help you verify your balance and permissions. Layer 2 network delays can sometimes lead to "ghost" transactions that appear much later.</p>
