Important Notice: WanWallet Desktop & iWan-RPC Server Will Be Temporally Out of Service on February 25th Due To Multi-chain Bridge Mechanisms Going Live on Wanchain Mainnet

Dear Wanchain Community:

Wanchain blockchain will make a brand-new upgrade to its cross-chain mechanism on February 25. The specific time and precautions are as follows.

Schedule

• 0:00 UTC+0, February 25th, 2021–0:00 UTC+0, February 26, 2021: The cross-chain mechanism of Wanchain mainnet is upgraded to Universal Multi-chain Bridges with Shared Staking Assets (for short, Multi-chain Bridges). WanWallet Desktop, wanBridge Web and iWAN-PRC server will be out of service for approximately 24 hours. (Note: The upgrade completion time at 0:00 on February 26 is the estimated time. The actual completion time may be earlier or slightly delayed. Please pay attention to Wanchain official announcement at that time)
• 4:00 am UTC+0, March 1st, 2021: The fourth Storeman nodes selection begins
• 4:00 am UTC+0, March 9th, 2021: The new version of Storeman Group with the Multi-chain Bridges mechanism starts working

As A Storeman Node Operator, You Need To Know:

1. You must upgrade the Storeman Agent between 0:00 UTC+0, February 25th and 0:00 UTC+0, February 26.

Your Storeman Agent will be automatically upgraded if you previously chose to support the automatic upgrade of the agent when you set up your Storeman node.

Otherwise, you have to manually upgrade your Storeman Agent if you did not select the automatic update mode when you set up your Storeman node. For details, please check the Section 3.3 Start Storeman Agent of Storeman Setup Guide.

2. The staking assets will be shared once the Multi-chain Bridges go live.

The cross-chain mechanism will be upgraded to Universal Multi-chain Bridges with Shared Staking Assets which is proposed by the Wanchain team to provide a high level of security and scalability. By then, all the wanBridges are run by a shared Storeman group with a shared staking deposit pool.

As A General User, You Need To Know:

1. WanWallet Desktop and wanBridge Web will be out of service on the 25th

From 0:00 UTC+0, February 25th to 0:00 UTC+0, February 26, WanWallet Desktop and wanBridge Web will temporally stop all services, including but not limited to ordinary transaction, cross-chain transaction, staking & delegating, etc.

So, please plan your crypto assets in advance.

2. WanWallet Mobile, WanMask, WanSwap and WanLend Will Not Be Affected

For the cross-chain mechanism upgrade at this time, the wallets of WanWallet Mobile and WanMask, the DeFi dapps of WanSwap and WanLend will not be affected. Those products will still be in service on February 25.

3. wanBridges for BTC cross-chain service will be out of service from February 25th to March 8th; Bitcoin-Ethereum direct bridge will be live on mainnet on March 10th; WanSwap will provide 1:1 two-way swap for the new wanBTC and the old wanBTC

For the cross-chain mechanism upgrade at this time, there will be a new highlighted feature is that the Bitcoin-Ethereum direct bridge will go live on Wanchain mainnet. By then, the cross-chain quota for BTC will no longer be limited to 10 BTC which is the current quota of BTC cross-chain Bridge.

Affected by this, the BTC cross-chain service will be suspended from February 25th to March 8th. In other words, the BTC cross-chain function in WanWallet Desktop and wanBridge Web will be unavailable during the time.

After the Storeman Group with the Multi-chain Bridges mechanism enters to the working status on March 9th, the brand-new Bitcoin-Ethereum direct bridge will come out. At that time, you can directly transfer your BTC from Bitcoin network to Ethereum through WanWallet Desktop or wanBridge Web. Here is the article to explain the difference between Direct Bridge and Two-way Bridge.

For users who currently hold wanBTC, it is important to point out that you need to swap your original wanBTC tokens to new wanBTC tokens by 1:1 ratio through WanSwap after we deploy a new contract on March 9th. We will release the specific user guide before March 9th. Stay tuned.

4. BTC, ETH, EOS, ERC 20 tokens will be integrated to Multi-chain Bridges Mechanism, and the integration of XRP will be live in March.

You could use WanWallet Desktop or wanBridge Web to enjoy this Multi-chain mechanism and the Bitcoin-Ethereum direct bridge function.

If you have any questions, feel free to contact us or join Wanchain Telegram group. We will feedback your questions.

Thanks so much to you all for the long-term support for Wanchain!
