Are there any fees involved?
For cross-chain transfers, you need to pay two fees:
Gas Fee: Paid by your wallet connected to the From chain for the transfer.
Transaction Fee: Collected by ETransfer in cross-chain tokens to cover the gas fee on the target chain. This fee may vary depending on the network and the level of congestion on that network.
What is the difference between the Transfer and Deposit features?
The specific confirmation time depends on the third-party network. Confirmation on the aelf network is faster. Confirmation usually takes about 4 minutes. You can check the estimated completion time of your transaction on the history page.
ETransfer currently supports two main cross-chain functions: Transfer and Deposit.
Transfer: Supports cross-chain transfers of a single token between any two chains.
Deposit: Allows users to transfer assets from any chain to the aelf MainChain or aelf dAppChain. It also supports swapping during the cross-chain process.
What is the 24-Hour Limit shown on the transfer page?
The 24-hour limit indicates the maximum amount you can transfer within 24 hours, both individually and in total. This helps manage daily transfer limits for security.
