Why should dApps verify final ledger state?
A submitted response is not the same as final business confirmation.
WalletConnect and payload responses can include submission results, but payment-critical apps should still verify the final validated ledger transaction.
For payments, check the transaction hash, result code, delivered amount, destination, currency, issuer, and destination tag when relevant.
This protects dApps from network timing, partial-payment semantics, and redirect-only assumptions.
