When withdrawing XDC (XinFin Network) from an exchange to OneKey, you may encounter a prompt:
"Invalid address format"
This is because:
OneKey displays XDC addresses starting with 0x (EVM standard format)
Some exchanges require addresses starting with xdc (XDC official format)
The addresses in both formats are essentially the same, only the prefix is different. Simply change the prefix of the OneKey address from 0x to xdc:
Example
OneKey displays:
0x74b543A6BB671b47ecAc30dbCd78B82394352786
When withdrawing from an exchange, change it to:
xdc74b543A6BB671b47ecAc30dbCd78B82394352786
👉 Only replace the prefix, do not modify any subsequent characters, otherwise your assets will not arrive.
The address prefix difference comes from an official XDC upgrade announcement: https://medium.com/xdcnetwork/xinfin-releases-new-address-prefix-starting-with-xdc-75750a444f77
