How to use Radex? Step by step tutorial

If I try to sell STN by clicking Sell button on Buy Orders table, I see wrong labels as I think.

  • Amount (how STN I want to sell, not eth)
  • Total (how much ETH I will received, not STN)
  • Fee, also maybe in STN, because I sell STN.

Amount = 0.1 STN
Price 1 STN = 12 ETH
0.1*12 = 1.2 ETH
So, saller must received 1.2 eth
But it’s my tx. And I was receive only 0.097 eth (0.1 eth-fee, as I understand)


By this tx I was sell STN (or buy 0.1 eth) with price 0.08eth=1stn
So I sold 1.25 STN, not 0.1
And in Total line must be (Amount/Price) 0.1/0.08=1.25
But now there wrong formula (Amount*Price). This formula will be right if in Amount we will put STN. But now there ETH




New release has been deployed yesterday, thank you for your feedback @investblog


Thank you for fixing! After testing I say YES it’s all good now :blush:


Found a little buggy thingie.

Was trying out/getting to get acquainted with your trading platform. When I tried to trade with the ZRX/ETH pair, I found out one needs to pay a small fee, for the ERC20 to ERC223 conversion (no probs with that). But I found out, I was out of ETH on my MetaMask account, so I tried to close the trade, by clicking on the ‘X’ mark on top, Without success - no response.

Is that a bug or a feature? xD


It’s a feature, but we could have explained it better.

What happens when you click on upgrade is you call zrx.approve(zrx223.address, zrx.totalSupply()). This lets our ERC223 upgraded zrx manage your funds in the ERC20 ZRX token. As per usual, every ethereum transaction requires a small fee to be processed.

The X button closes this popup window (or a modal in bootstrap-speak) and will take you to the trading screen. But you won’t be able to trade without upgrading your ZRX, hence we don’t let you close it.

Currently Radex doesn’t have a read-only mode. You can only get through to the order book if you made sure to complete all the prerequisites for trading.

We have some plans to enable read-only view in the future. In the meantime I suppose we need to either hide the X button or make it more obvious that it’s disabled.


That’s the thing, the ‘X’ does not close the pop-up window. Or is it just me?

Edit: scratch that, misread it (the disabling part)

Edit#2: maybe call another popup upon the onClick on the ‘X’ button, that offers the user a redirection to the main menu of your exchange, and in it, an explanation why.


Max amount of token transfer is only 999.


Fixed & deployed today
