Check a sent transfer and the Smart Vault balance before trying another one.
Do not send it again yet. Check the same transfer in your sending wallet and compare its recipient, network, asset, and amount with the current Smart Vault receive details. Use Check add-funds status if Chain shows a pending direct-deposit attempt. For a bridge, check the route and destination status too.
After a confirmed result, refresh the vault balance. An empty activity view does not prove no transfer occurred. If the details match but the balance still looks wrong, follow funding troubleshooting and keep the transaction hash for support.
