The 2 options are a Metamask wallet and the Republic wallet.
While a Metamask wallet can be linked from a number of places on the INX.One platform, the Republic wallet can only be linked through the Note trading page.
Only one wallet can be linked to INX ONE at any given time, however either wallet can be used to trade all available securities on the platform, including the Note. If you already have a Metamask wallet linked then you can continue using that wallet for trading the Note as well.
Users that already have a Metamask wallet linked and want to link a Republic wallet instead will have to contact inx-support@republic.com and request a wallet change.
