1. Is it necessary to swap tokens?

Answer: Yes. If you have ERC-20 tokens, it is necessary to swap into Mainnet NAS coins. ERC-20 NAS token were released before the Nebulas mainnet launch (March 30, 2018) and represents your ownership of Mainnet NAS coin. After the token swap, ERC-20 tokens will no longer be supported by the Nebulas team. Additionally, exchanges will stop accepting ERC-20 NAS tokens.

2. What about gas fee?

Answer: The gas fee will be used as payment to the miners/transaction fees as well as any additional expenses on the Ethereum network. The transaction fee is required to assure the transaction will be completed successfully. The specific required gas fee will be automatically adjusted based on the current network load/status of the Ethereum blockchain.

3. What if the gas fee transferred too much?

Answer: If the transferred gas fee exceeds the required amount when the swap takes place, you will be able to import your Ethereum address into another wallet via your mnemonic phrase and withdraw/transfer any remaining ETH. In addition, to successfully complete the token swap, you will be required to backup your mnemonic phrase. Please be sure not to remove any ETH gas or NAS tokens until the token swap is complete.

4. What if I failed to transfer tokens into NAS nano from another wallet?

Answer: NAS tokens can be transferred from Ethereum wallets that support token transfers(such as MyEtherWallet). If you do need assistance, make sure to clarify what type of wallet you are using for transferring tokens to NAS nano. During token swap, you can only transfer ERC-20 NAS and GAS ( ETH ) to the specified ERC-20 wallet used for token swap. If the token swap fails, you can: 1 ) verify your network; 2 ) Check whether the transaction has been recorded and is successful in the Ethereum blockchain; 3 ) verify that the gas ( ETH ) in your wallet is sufficient as per the recommendation in NAS nano.

5. Are there any other wallets that support the token swap?

Answer: No. NAS nano v2.2.0 is the only wallet that supports the self-service token swap and the only official token swap channel. Please pay attention when downloading NAS nano and be sure to download from the official channel.

6. Will the token swap period be extended?

Answer: Currently, the token swap is progressing smoothly. If most of the ERC-20 NAS tokens have been successfully swapped into Mainnet NAS coins by the end of the token swap period, we will not extend the swap time. It is imperative that all ERC-20 NAS holders swap their tokens within the time allotted.

7. Besides swapping tokens via NAS nano, are there any other methods to complete the token swap?

Answer: Yes. You can complete the token swap through exchanges. Currently, huobi.pro and Gate.io fully support the NAS token swap. For more information, please refer to official notices from the exchanges.

8. Will Nebulas complete a second token swap via NAS nano wallet after October 30?

Answer: The NAS token swap will cease on October 30(16:00, UTC+8). After the deadline of the token swap, ERC-20 NAS holders will no longer be able to apply for the NAS token swap via official Nebulas channels. The Nebulas team will not re-open the token swap via NAS nano wallet.

9. If I send ERC-20 NAS to huobi, will it be directly swapped to mainnet NAS coin when I withdraw from huobi?

Answer: Yes. Exchanges huobi and gate.io will automatically swap the ERC-20 token to mainnet NAS coins.
