When initiating a transaction on the Tron cross-chain bridge, you need to encode the transaction details into the transaction memo. According to the latest TRX network protocol, each transaction requires energy and bandwidth as gas fees. Adding a memo consumes an additional 1 TRX. If you lack sufficient energy and bandwidth, here are actionable solutions:
Why Is My Bandwidth Always 0?
This indicates your account hasn't been activated. Transfer TRX into your account to activate it. Once activated, your account receives 600 B of free bandwidth every 24 hours.
To execute transfers, you’ll need bandwidth and energy resources. If your wallet lacks sufficient TRX to cover these, transfers may fail or prompt "insufficient bandwidth."
Pro Tip: Deposit 50–100 TRX into your wallet to activate the account and support future transactions.
Understanding Bandwidth and Energy
- Bandwidth: Represents the byte size of a transaction. For example, a 250-byte transfer consumes 250 bandwidth units.
- Energy: Measures the time consumed by smart contract execution (e.g., 100 μs = 100 energy units).
How to Acquire Bandwidth and Energy
Method 1: Burn TRX (Recommended)
Deposit 50–100 TRX into your wallet. Transactions will automatically burn a small amount of TRX to cover bandwidth/energy costs.

Method 2: Freeze TRX
- Go to Asset Overview → Resource Management.
- Select Bandwidth or Energy.
- Freeze 2000–3000 TRX (can be unfrozen after 3 days).
Key Notes:
- All transactions consume bandwidth.
- Energy is required for smart contract calls (e.g., TRC-20 transfers or DApp interactions).
- Activated accounts get 1500 free bandwidth daily for TRX/TRC-10 transfers.
- Frozen resources replenish over 24 hours after use.
FAQ
Q: Can I use imToken without TRX?
A: No. TRX is essential for gas fees. Deposit at least 50 TRX to start.
Q: How long does frozen TRX take to unfreeze?
A: 3 days. Plan ahead to avoid liquidity issues.
Q: Why choose burning over freezing?
A: Burning is instant; freezing suits long-term users needing recurring resources.
Q: Are bandwidth/energy costs fixed?
A: No. They vary by transaction complexity and network congestion.
