How to secure SDK that facilities payment from one bank to another bank

Hi there, I would like to check how to secure payment from one bank tenant to another bank tenant id with Visa as the facilitator.

Let's say if the bank issuer were to generate a public key and send it to the payment sdk.

The payment SDK generate a shared secret and send it to bank issuer.

Is there a risk such that the bank will actually spoof it.

The parameters required, the tenant details, the mobile number , the countrycode etc to generate a public key which can be understood by the SDK.
