Possibly, although I wouldn’t recommend it.
Not only are you introducing a single point of failure for two sites, but also it will be harder for you to tell if your reserves are sufficient to back the user balances. Normally you can tell what percentage of the total of the user balances is online, by visiting the adapters page or the cold wallet storage. If you link two sites to one wallet account then it will be harder for you to tell.
In the future please note that this forum is for the main plugin. The support forum for the CoinPayments adapter extension is at https://www.dashed-slug.net/forums/forum/coinpayments-net-coin-adapter-extension-support/
Thanks, I’ll remember for any future inquiry.
