How to swap your SPC tokens from QRC-20 to ERC-20
SpaceChain has adopted a dual token model – ERC-20 and QRC-20 — to expand our footprint and engage with additional communities of developers. The QRC-20 SPC token and ERC-20 SPC token will have a 1:1 swap exchange rate. The token supply that will be circulating will remain at 1,000,000,000 SPC. The QRC-20 SPC tokens and ERC-20 SPC tokens will remain interchangeable through authorized wallet services.
If you choose to swap your SPC tokens from QRC-20 to ERC-20, see below for details on when the swap will take place on QBao Wallet as well as these exchanges: CoinEgg, Coinnest and EXX.
| Participants: | Holders of QRC-20 SPC |
| Swap Exchange Rate: | QRC-20 SPC : ERC-20 SPC = 1:1 |
After the swap, CoinEgg, Coinnest and EXX will begin to trade ERC-20 SPC tokens while HitBTC and Exrates will continue trading QRC-20 SPC tokens.
You can swap your tokens through either of these methods:
METHOD 1: AUTOMATIC SWAP THROUGH EXCHANGES
| Token swap process start time/date: | September 14, 2018 (11:59 AM, UTC+8) |
| Token swap process end time/date: | September 17, 2018 (11:59 AM, UTC+8) |
| Supporting Exchanges: |
|
- Deposit your QRC-20 SPC to exchanges prior to 11:59 AM (UTC+8) on Sept 14 (Friday). The swap will take place automatically.
- All SPC deposits and withdrawals through exchanges will be suspended at 11:59 AM (UTC+8) on Sept 14 (Friday). Do not deposit any tokens at the original address after that time.
- SPC deposits and withdrawals will resume at 11:59 AM (UTC+8) on Sept 17 (Monday) after the main network has been switched over. Please check the individual exchanges for when they will resume trading after the token swap. Those announcements will be made on their official channels.
- Exchanges will only support deposits and withdrawals of ERC-20 SPC after the swap. Deposit and withdrawal at the old SPC address will not be available. For your asset security, please make sure that you are entering the Ethereum address when depositing or withdrawing.
METHOD 2: SWAP THROUGH WALLET
| Token swap process start time/date: | From September 14, 2018 (11:59 AM, UTC+8) |
| QBao Wallet | https://qbao.fund |
QBag, a centralized wallet on QBao Network, will be supporting the SPC swap from Sept 14, 2018. This swap channel is available in the long term and users can swap on QBag at any time. However, you will need to perform the swap yourself. Please stay tuned for announcements on SpaceChain and QBao’s official website.

The total sum of QRC-20 and ERC-20 tokens is 1 billion. I think the circulation should be controlled by the foundation. To show trust to investors, could you share the foundation’s wallet address so that the investors can see the current QRC-20 to ERC-20 ratios of the SPC token. In other words, we’d like to know the total SPC circulation and ratio of QRC and ERC at any given time
