## Transaction Fees

| Operation | Cost |
|-----------|------|
| TRX transfer | ~1 Bandwidth |
| TRC-20 transfer | ~15,000 Energy |
| Contract call | Varies |

## Troubleshooting

**Not enough bandwidth:**
```bash
# Check bandwidth
curl -s "https://api.trongrid.io/v1/accounts/YOUR_ADDRESS/resources" | \
python3 -c "import sys,json; d=json.load(sys.stdin); print(f\"Bandwidth: {d.get('freeNetLimit',0) - d.get('freeNetUsed',0)}\")"
```
Solution: Wait (regenerates) or freeze TRX

**Not enough energy:**
Solution: Freeze TRX for Energy or pay TRX for transaction

**Token not showing:**
Assets → Add Token → Paste contract address

**Transaction pending:**
```bash
# Check transaction
python3 -c "
from tronpy import Tron
client = Tron()
tx = client.get_transaction('TX_HASH')
print(tx)"
```
