Trade on iSwap in 3 Steps:



1. Transaction Speed Calculation Method

Speed calculation = the time when the second chain transaction is completed — the time when the first chain initiates the transaction (it is allowed to increase the GAS fee to increase the speed)

Example: Swap HT to BNB, the transaction speed is from trade the HT on the HECO chain to the time of the user received the BNB on the BSC chain.

2. iSwap Handling Fee

iSwap only charges 0.2% cross-chain handling fee. During the Speed Challenge Campaign period, the cross-chain handling fee will be 0.004%. The rest of Gas fees and transaction fees are charged by the corresponding chains and Dex.

3. What is Relayer Gas Fee?

The transactions you initiate in the original chain are directly deducted from your account for the gas fee; while the transactions in the target chain need to be completed with the assistance of the relay account, and the gas fee is advanced by the relay account, so the target chain will charge the estimated gas fee equivalent USDT to purchase HT/BNB to replenish the relay account.

4. Where to find my assets after swap?

For now, all chains iSwap supported are ETH series chains, which means they share the same address. After swap, you can switch your wallet to the target chain to check your assets at the same address.

If you need to connect your wallet to the corresponding chain, please refer to:

How to connect metamask to HECO?

How to connect metamask to BSC?

5. Exceed Maximum Transaction Amount

In order to prevent excessive slippage from causing losses to users, the platform limits the upper limit of the amount of a single transaction. If you have a large exchange requirement, you can complete the trade in several transactions.
