K STADIUM Bridge is a service that supports token exchange between different networks. Currently, K STADIUM’s tokens are on the GroundChain network, in order to use Ethereum Mainnet tokens in the K STADIUM app, a conversion process is required. With the K STADIUM Bridge, Ethereum-based tokens can be moved to the K STADIUM Mainnet. Depending on the network environment, it takes about 5 minutes, and a tax with 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.
