How to use the Bridge
Step-by-step guide on how to use Impel's R3 Corda | XDC Network Bridge
General concept
Impel's bridge allows digital assets "cryptocurrency" such as XDC, the native coin on the XDC Network, or XRC-20 tokens, which are Layer 2 projects built upon the XDC Networks blockchain, and Fathom FXD stablecoin to be moved from the public XDC Network's blockchain to R3 Corda's private DLT platform, specifically to any CorDapps on the Corda Network.
Digital assets moving from the XDC Network need to be located in a digital asset wallet, such as the XDCPay wallet, which is a browser extension plugin.
Prerequisites
First, confirm that the XDCPay wallet has been installed on the device you want to use to process the transactions.
Download the XDCPay wallet here.

Step-by-step guide on how to use Impel's R3 Corda | XDC Network Bridge
(Step #1) Access the R3 Corda | XDC Network Bridge by submitting your request here.
(Step #2) Be sure that XDCPay wallet has been installed and logged into an XDCPay account (Image 1).
(Step #3) Ensure that the XDCPay wallet is connected to "XDC Mainnet" (Image 2).
(Step #4) Select which XDCPay wallet account to send/receive digital assets from. Note: Example in Image 2 shows "Account 3" as the selected "active" account that is associated to the proper XDC Network wallet address (i.e. xdc53e3...cb3e shown below in Image 2).
Note: Currently only authorized "whitelisted" wallet address are eligible to connect to Impel's R3 Corda bridge. For access, contact Impel's team to request access here.
Once your address has been whitelisted please follow the steps below.
After you choose the settings for XDCPay, click the CONNECT WALLET button (Image 1).
(Step #5) Access the Send tab by clicking on "Send", allowing for digital assets to be sent to a CorDapp. (Image 3)
Enter the required information into the following text fields:
Digital Asset - Select the desired asset (currently, supports XDC)
Amount of Digital Asset - Amount of digital asset to be sent to a CorDapp
Destination CorDapp - Destination to where the digital asset is going to on the Corda platform
Destination Address - The specific CorDapp's account address. Example: CordApp account address (e.q account-1@OU=xinfin, O=xinfin, L=London, C=GB)

(Step #6) Once all data has been entered correctly, the Send button is activated. Once clicked, a successful transaction confirmation message will appear, else a notification of failure will be displayed.
