NKN Mainnet Token Swap Opens

Since our NKN Mainnet launched on July 1st, 2019, we have continuously improved the security and scalability of our mainnet. In addition, we are building flagship products (e.g. nCDN) and innovative applications (e.g. D-Chat) on top of the NKN mainnet, which fully utilize NKN technology and token economy. Now it is time to start the NKN token swap between mainnet and ERC-20.

Today we have launched our official mainnet token swap web tool.

  • This is a two-way swap between mainnet and ERC-20.
  • This swap has nothing to do with NKN test tokens (tNKN) or NEP-5 tokens.
  • All exchanges are currently supporting ERC-20 NKN token for trading purpose. The schedule for exchange support of NKN mainnet token will be announced at a later stage.
  • This is the first test run of the swap tool, and is open now until September 30, 2019.

The official swap tool is located here:

Mined token is NEP? I want to make sure.

No, mined token has nothing to do with NEP(NEP-5)

I tried to swap, but it reminded erc20 that there was not enough tokens. I looked at it. There were not enough tokens on the exchange address.

It is working now.
