K STADIUM Use Bridge

Opening a new way between cryptocurrencies.

K STADIUM Bridge is a service that supports token exchange between different networks. Currently KOK is on the ERC-20 network and is an Ethereum based Mainnet token. In order to use Ethereum mainnet tokens in the K STADIUM app, a conversion process is required. With the K STADIUM bridge, Ethereum KOK can be moved to the K STADIUM mainnet. Depending on the network environment, it takes about 5 minutes and a small fee will be incurred by the Ethereum network itself.

The K STADIUM-specific Bridge provides a safer and faster way to transfer assets between two chains. For reliable conversion, K STADIUM Bridge uses the HashedTimeLock feature. Both the From network and To network require respective authorization processes. As the process may take a long time, please continue to monitor the transfer of assets through the Bridge screen or Explorer. The asset can be moved from the desktop web by connecting the wallet in the form of a browser plug-in, and please refer to the guide below at K STADIUM Bridge.

KSTADIUM app supports only wallet-to-wallet transfers between users, and in this case, a small amount of Tx fee varies depending on the network situation. Please be aware that Ground Chain-based KOK cannot be sent to an exchange or Ethereum-based wallet address.

Currently, Bridge Service also supports only one-way support with Form:Etherium-To:Groundchain, but we will soon release it in two-way so that Groundchain’s KOK can be transmitted back to Ethereum-based KOK. Please refer to it when you use it.

If you want to convert more than 20,000 KOK,please contact us through the K STADIUM Help Center before proceeding with the conversion.
