Recently, many friends have asked how to operate after the FAB upgrade to the new version of pay.cool, why their assets on the exchange are not visible in pay.cool, and other related questions. Today, we will answer everyone through a Q&A format.

In fact, the V3 version of pay.cool has been officially launched for quite some time, and an announcement was made at that time.

  1. Can't find the old version software download and website?
    Currently, the old version (i.e., V2 version) software has been removed from the shelves, and the official website no longer provides downloads, with the aim of encouraging everyone to transition to pay.cool+ (i.e., V3 version) as soon as possible. At the same time, the V2 version has restricted users from transferring coins to the exchange.

However, many people's assets are still in V2, so the official team has kept V2 open and has not completely shut it down, providing a channel to transfer from the exchange to the wallet.

If you have not uninstalled the Yibi app, the old version of the Yibi app is still usable and supports transferring from the exchange to the wallet.

If you have already uninstalled the old version of the software, you can access the old version (V2 version) through the following URLs:

Old version V2 Yibi Decentralized Exchange: https://v2.dex.cool/
Old version V2 Biswap: https://v2.biswap.com
The URL for the new V3 version can be accessed by simply removing the "v2." from the front, just like before, unchanged. After entering, import the mnemonic phrase, and you can proceed with operations. You can refer to previous tutorials; the operation is very simple.

As long as you import the mnemonic phrase, the assets in the wallet are the same regardless of the version.

  1. How to transfer assets from the V2 exchange to the new V3 version?
    If your assets are in the old V2 version, you just need to transfer the assets from the exchange to the wallet in V2.

Then, simply import the same mnemonic phrase in the new version of pay.cool, and you will see your assets in the pay.cool wallet.

If you want to trade, just transfer the assets to the Kanban chain in pay.cool to trade and participate in various ecosystems within pay.cool.

  1. Where is the V3 version of the Yibi Decentralized Exchange, and how to trade?
    We have previously detailed how to trade in the Yibi exchange on pay.cool in our tutorials. You can click on the channel avatar to find it directly.

Additionally, you can click on the browser at the bottom of pay.cool and click on DEX.cool to enter the Yibi Decentralized Exchange for trading.

You can also click on Biswap or RIS to trade.

Again, we remind everyone that the mobile version only has this one V3 version of the software, and subsequent various ecosystems and applications will only be available in pay.cool.

We recommend that everyone transition to the V3 version as soon as possible; the old version will not be updated and will only retain basic operations, and the V2 old version can no longer transfer coins to the exchange, and it will gradually be phased out.

As the ecosystems on pay.cool continue to grow, trading will become more frequent, and future policies will only be implemented in the V3 version of pay.cool.

  1. How to remove previously added liquidity from staking in the old V2 version of Biswap? What about the rewards?
    If you have not uninstalled your old Biswap software, you can directly enter, find your liquidity, and after clicking in, the delete button in the upper right corner can directly revoke the liquidity.

You can also log into the above V2 version of the Biswap website, link your wallet, click on liquidity, find your liquidity, and you can directly revoke the liquidity.

You can click to redeem rewards on the rewards interface.

The revoked coins and reward coins can be directly transferred to the wallet, and then transferred to Kanban in pay.cool to participate in trading.

You can also click on Biswap in the pay.cool browser to stake again in the V3 version of Biswap.

  1. How to withdraw coins from the exchange to the wallet in the V3 version of pay.cool?
    The Kanban chain we have been talking about is actually the exchange mentioned earlier, which has been separated in the new version for easier viewing and for the development of the FAB public chain's subsequent ecosystems.

When you enter pay.cool and select the Kanban chain, you can see various assets. Click on a specific coin, and below it will be the option to transfer back to the wallet; click in to operate and transfer back to the wallet.

  1. Why can't I operate to transfer back to the wallet on the Kanban chain?
    Transferring back to the wallet in the new V3 version requires the corresponding main chain coin on the Kanban chain as a fee. There will be a prompt when transferring back to the wallet.

Because the old V2 version often encountered issues with insufficient fees when withdrawing coins from the exchange, the V3 new version requires direct payment of the corresponding main chain coin as a fee when transferring back to the exchange, solving the blockage issue.

For example, if you want to transfer USDT on the BNB chain back to the wallet, remember to have BNB on the Kanban chain as well; about 0.01 BNB can be used many times.

As you know, trading, transferring, and participating in ecosystems on the Kanban chain will only consume a small amount of FAB as fuel and will not consume others, so as long as you are not transferring back to the wallet dozens or hundreds of times daily, basically 0.01 BNB can last a long time.

Transferring USDT on the Tron chain requires TRX, and Ethereum chain requires ETH, etc.

  1. Where can I download the new version of pay.cool?
    You can go to the pay.cool official website, scroll down to find the QR codes for the Apple Store or Google Store, and install directly.

You can also search for pay.cool in the Apple Store or Google Store for installation.

Alternatively, you can enter the URL in your browser to download:

Watching the tutorials a few more times will help, as they are relatively simple.
