ioTube v6 Testnet Release

We have just launched ioTube v6 to testnet. With this release we now unify the liquidity of the stable coins from certain chains including support for cUSDT.

Visit if you would like to test this ioTube release. Connect your MetaMask or ioPay mobile wallet to ioTube v6 Testnet and use a token faucet to get test tokens in order to test this new release. We would love to hear any feedback you have on this release including what works, what doesn’t work, and what you would like to see next! Developers, feel free to build on top of our testnet release. We are looking forward to our Mainnet release which will be coming soon and will also include support for cUSDC and cBUSD tokens as well as the long list of tokens we supported in the v5 release.

Some instructions on how to use ioTube v6 are below:

Step 1: Connect your MetaMask or ioPay wallet.

Step 2: Select the token you would like to transfer.

Step 3: Enter the wallet address you would like to send tokens to OR simply hit “my wallet” in order to send tokens to the wallet you have connected.

Step 4: If you have no tokens to test with then look for a faucet. For example you can receive testnet IOTX at

Step 5: Enter token amount then hit deposit

Step 6: Confirm Transaction both on ioTube and your wallet.

Note: Using our crosschain token feature you can wrap or unwrap a token at a 1:1 ratio anytime.

Check out and let us know what you think!


Testnet Feedback

Hai, my name is Loki , firstly im so glad to be part of this community by joining your test activity ! and i have tested your website/apps using this address 0x2Db4625A9eCe077CB432D1A84b85b03c15721BE6 recently, cuz you ask us to give some feedback what works and what doesn’t, here are my thoughts :


  1. I can’t change network through your web (chain menu on top) , everytime I clicked on different network, it always says "wrong network bla bla bla chain id…), BUT when I change my network on my metamask MANUALLY, it works, I mean I can now use your web with the selected network.

  2. Your transaction history feature isn’t works at all ! I have done some crosschain token transfer but there is not any transaction history !


Hello my name is tribagus I have tried Testnet iotex v6 This is my address 0xfF3E1859D44897c90B19894BaEBDD2d1f1FabCa0
I’ve tried it and there are some problems

  1. Why every network change always Directly disconnected to wallet connection? I think it’s a bit too fast
  2. Too Fast Bug for switching between System functions Cross chain I always experience disconnection to the network.

+/positive the applications are all very simple and comfortable to use Not too heavy for the size of the website and very fast for transactions

Hello. My name is Randi. I have tried Testnet iotex v6 using my address :
I’ve tried it and there are some problems

There is an error "tokenContract.approve error The execution failed due to an exception." on second time I try the Crosschain Token swap.
I had made the cross chain and on the blockchain scan  it told success but the token is not transferred yet to Iotex from Kovan

The positive about the dapp is so simple and easy to use, fast in loading and has a good reliability.

when it comes to transaction problems from kovan to iotex testnet it’s easy, there are almost no problems on the usdt network, but why can’t it be from iotex to kovan?
for the others it’s normal there are no problems
