Guide: tNKN swap to ERC-20
Read me first
Ratio of swapping tNKN in testnet to ERC-20 NKN is 5 : 1。Please do a test swap with a small amount of NKN tokens before you swap a very large amount of tokens.If you have question, please contact our customer support swap@nkn.org directly.Fill in the details
There are three inputs you need to enter:
1. Testnet wallet address FROM where you will send your tNKN token. We show here screenshot from testnet wallet, where to find this address.
2. Amount of tNKN you want to swap: e.g. 1,000.
3. ETH wallet address TO where you will receive your ERC-20 NKN token. We show here screenshot from Metamask wallet as Chrome browser plug-in.
In the following example, you can find out your tNKN address from NKN testnet wallet. This address should start with letter “N”.
In the following example, you can find your Ethereum address from Metamask wallet. The address should start with “0x”.
Once you collect all the information, you can enter into the web tool as below. Then press “Next Step”.
Although the email address is optional, we still recommend that you provide an email address that will normally contact you.
Transfer tNKN tokens
One you press “Next Step” from Step 2, you will find a similar screenshot on your https://swap.nkn.org website. This is a summary of your swap order, with all the information you previously entered, as well as an Order ID, and swap status.
Please record your Order ID now, for future reference in case of issues.
This screen also shows you a very important address: “tNKN payment address”. You will need to transfer your tNKN tokens from your wallet to this “tNKN payment address”.
Important note: you have to transfer the EXACT same amount of NKN token as specified in the swap order. Otherwise the order will be rejected.
We show an example of such transfer from tNKN wallet. Your wallet may have a different user interface and procedure but the concept should be the same.
Click "Transfer"
A Transfer Dialog pop up, paste TNKN payment address to "Transfer to address"，enter amount of tNKN token and wallet password，click "TRANSFER"，your tNKN will be sended to tNKN payment address

Using the token swap web tool https://swap.nkn.org, when you press “Next Step” within the dialog from Step 3, or if you click on the top right corner “History” menu, you can see the progress of your token swap order
There are small confirmation time on both the NKN testnet and Ethereum blockchain, but this swap should not take more than a few minutes. Please record your Order ID, in case you cannot get token swap completed successfully within a reasonable amount of time (for example, 4 hours or more).
