When you ask "what is the HEI fee", if you mean the digital currency Heima (its token is HEI), then the fee depends on the type of transaction and the platform you are using:
---
💱 1. Trading commissions on platforms.
- LBank platform:
Trading fees (Maker or Taker) for the HEI/USDT pair are 0.2% for each party in the transaction.
- BingX platform:
Licensing and instant trading fees are low, reaching 0.1% for both Maker and Taker.
---
🌉 2. Network bridge fees (Bridge Fees)
When transferring HEI between the Heima network and the BNB Chain:
From Heima to BSC, a fixed fee of 1 HEI is deducted.
From BSC to Heima, only the gas fee is deducted, without additional HEI deduction.
---
🛠 3. Network fees and interactions within the system.
Transaction execution fees and interactions on the Heima Layer‑1 network are done using HEI itself as Gas, such as sending HEI tokens, voting, or interacting with smart contracts. They vary according to network load and transaction size.
HEI can be used as an official token to pay Gas fees across multiple networks, thanks to the "Gas Abstraction" technology that makes HEI the effective intermediary without the need to hold different network tokens.

🧭 Why are these fees important?
Trading fees depend on each platform (Spot or Futures).
Bridge fees are fixed on one side only, while the other side only bears the gas costs.
Gas fees within Heima are deducted by HEI, so you must have HEI balance in your wallet to use the network.

✅ Important tips
1. Check the fees on the platform you are using to buy or withdraw HEI.
2. Keep some HEI in your wallet to cover bridge and transaction fees.
3. Before executing any bridge or withdrawal, ensure the network type (ERC‑20, BSC, etc.) and the current Gas cost.
