Common issues

​

Transactions fail

If transactions fail during testing or after launch, common causes include the following:

• Insufficient funds to cover gas or rent.
• Contract errors or RPC-related failures.

​

App doesn’t show in the Explore tab

If your app isn’t visible in the Explore tab, it’s usually because of the following reason:

• Cause: Your app profile changes are still under review.
• Solution: Wait for Phantom to approve the updates. Once approved, changes appear immediately.
