Vaulta transactions require CPU (processing power) and sometimes NET (network bandwidth). An "Insufficient CPU" error indicates your account lacks these resources for your intended action.
How to fix”
1. Switch to your Vaulta account and tap “Rent CPU” in the function bar.
2. Open Unicove and connect your wallet.
3. In the CPU/NET fields, input desired amounts (e.g., 10 ms CPU, 200 kb NET). Click "Rent for 0.0XX A" (the fee) and confirm the transaction.
4. Once the rental transaction confirms, return to your Vaulta account homepage to perform your transfer.
Note: If you're planning on making several transfers or performing other actions like staking or unstaking, it's a good idea to rent a bit extra CPU and NET to avoid hitting this limit again too soon.
