Troubleshooting

Not enough bandwidth:

# 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:

# Check transaction
python3 -c "
from tronpy import Tron
client = Tron()
tx = client.get_transaction('TX_HASH')
print(tx)"
