0xBeginning.Format required by some exchanges (XDC official standard): Some exchanges have adopted the address display specification officially recommended by XDC, and it is mandatory that the receiving address must be
xdcBeginning.
These two formats point to the blockchain same physical address, they are essentially the same, only the "prefix" at the beginning is displayed differently.
