Instabridge does not have any fees, however, you will need some ETH in your wallet to cover the Ethereum gas fees to convert between eXRD and XRD. For more information on how to exchange eXRD for XRD through Instabridge, please read our guide.
Instabridge is an optional service which allows anyone to quickly convert back and forth between eXRD and XRD, moving value freely between Radix and Ethereum.
eXRD won’t go away after the launch of the XRD token on the Radix mainnet. Instead, eXRD will continue in parallel with XRD, so users are able to freely convert back and forth between the two at a ratio of 1:1. This means that eXRD will become simply a different form of XRD that lives on the Ethereum network, and can be used with Ethereum DeFi applications. When users prefer to have their XRD in native form on the Radix network, they can move them there to participate in Radix staking, pay network fees, and later (in the Babylon release of the Radix network) use them in Radix-based DeFi applications.
