### **Troubleshooting: Deposit Failures (RPC / Network Issues)**

In some cases, users may experience failed deposits due to factors that are **outside of DeriW’s control**. These issues are mainly related to:

#### **1. Wallet RPC Connection**

Your wallet relies on its RPC endpoint to broadcast transactions. If the RPC is unstable, overloaded, or blocked by local network rules, deposits may fail to go through.

#### **2. User’s Local Network / VPN (“Proxy”)**

Some users access DeriW through a VPN or local proxy service.\
If the VPN is unstable or routing traffic incorrectly, it may prevent the transaction from being broadcast successfully.

Because both the **wallet RPC** and the **user’s VPN/proxy** are external to DeriW, we are unable to monitor or control these factors.

**Recommended Fix**

If you encounter a deposit failure:

1. **Try switching your VPN location or temporarily disabling it.**
2. **Change your wallet’s RPC endpoint** to a more stable one (most wallets allow you to select a different RPC).

In most cases, switching the network route or RPC resolves the issue immediately.
